Description
Technical field
The present invention relates to a kind of partition board of building decoration, particularly a kind of light cellular partition board production and processing method of processing with rice wheat straw.
Background technology
Since China's reform and opening-up, national economy is increased fast, becomes the main flow of China's industrial development with " scientific and technical innovation, autonomous innovation ".China's industry just progressively develops to the direction of economy type, energy-saving and emission-reduction, low-carbon (LC).Because the fast development of economic construction; China was increasing for the demand of timber in recent years; Annual coyoting denudation has caused the forest reserves in short supply, and the wasting of resources causes a large amount of soil erosions, desertification; The environment and the ecological homeostasis are destroyed, and China is being faced with the problem of forest reserves relative deficiency.China is a large agricultural country, and annual all kinds of agricultural crop straws have about more than one hundred million ton, a large amount of on-site incinerations of rice wheat straw, not only serious waste Limited resources, caused environment pollution again.The processing of agricultural crop straw is the major issue that we must solve, and causes that party and governments at all levels pay attention to.This shows that agricultural straw resource is abundant, utilizing agricultural crop straw to substitute timber is an effective way.Along with the development that urban modernization is built, multilayer, high-rise frame structure building are more and more, and to build a wall with hollow brick be to cut off and the partition of these frame structure building bodies of wall generally adopts; Need plaster, construction duration is long, has also strengthened built-loading; Like construction wrong, body of wall also is prone to the crack, during finishing in body of wall the assembly wire casing; Be not easy to constructor's construction, workload is big, and hollow brick is processed by clay simultaneously; Make a large amount of clays be used, be difficult to second ploughing, become the problem that always perplexs people's research.For addressing this problem, R&D institution and enterprise technology personnel utilize modern science and technology in constantly research, exploration, though obtained some progress technically, in practice, still exist the technical barrier that does not overcome as yet.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of light cellular partition board production and processing method of processing with rice wheat straw is provided, utilize rice wheat straw to be main filler, is material modified with several kinds of industrial chemicals, adopts modern science and technology; The multi-functional wallboard production line of developmental research, through machine extrusion process disposal molding, this light cellular partition board has in light weight, and sound-insulating and heat-insulating and waterproof and dampproof property performance are good; Fire line is strong, and intensity is high, and good toughness is saved operation; Reduction of erection time, reduce the building deadweight on the one hand, the structure floor space is little, increases building area; Simultaneously reduce construction costs yet, can saw during finishing and can dig, brill punches, and crackle is not indeformable, can spray, is coated with, coats with lacquer; Improve efficiency of construction, can not produce formaldehyde and radioactive pollution, both be applicable to interior decoration, be applicable to the partition wall of outer body of wall building again.
The technical solution adopted for the present invention to solve the technical problems is: by top plate and bottom plate, form with a central core; Fill one deck plastic foamboard in the middle of the central core, one deck bonding material layer is filled at around the plastic foamboard and place, slit, and compound one deck has glass layer on top plate and bottom plate, becomes a kind of light cellular partition board of processing with rice wheat straw; Batching has magnesium chloride, water, magnesia, flyash, selected rice wheat straw, basalt fibre, shell fiber, modifier;
The technological process of production: mould → release agent → wallboard machine → batching → shop layer of glass cloth → material loading is made bottom plate → be coated with one deck bonding slurry material → addings one deck plastic foamboard → be coated with one deck bonding slurry material cementation of fissures → shop layer of glass cloth → material loading making top plate → carry off → solidify → demoulding → cutting edge;
Processing method is: select Die and mould plate earlier, select the smooth no pit of surfacing, the consistency of thickness flexible has the indeformable sheet material of water resistance as Die and mould plate; The template after the demoulding is removed clean, thin up saponified oil obliterating release agent again, 1: 5 in proportion～8 dilute, the adjustment wallboard machine; Prepare burden, blending process is divided into processing rice wheat straw, preparation bittern and three operations of preparing modified agent, various raw material stirring is evenly got final product with mixer according to the requirement of filling a prescription; Usually add rice wheat straw, basalt fibre, shell fiber, magnesia, flyash inserts earlier, add bittern after stirring again, stir and to use; The batching of making sheet completes, and makes bonding again with material, is prepared in proportion by magnesia, bittern, flyash; Evenly stir and get final product shop layer of glass cloth, material loading making backplane level in the pasty state; On the bottom plate, be coated with one deck bonding slurry material, add one deck plastic foamboard, on plastic foamboard, be coated with one deck bonding slurry material cementation of fissures; Repave layer of glass cloth, material loading is made top plate, from make wallboard machine, carries off; Carry out the solidification process of light cellular partition board, the demoulding from template is by the specification requirement cutting edge.
The know-why that the present invention adopts: the rice wheat straw mix has magnesium chloride, water, magnesia, flyash, selected rice wheat straw, basalt fibre, shell fiber, modifier; Adopt artificial selected rice wheat straw as main filler; With several kinds of industrial chemicals is material modified, processes through machining.Utilize and contain a large amount of celluloses in the rice wheat straw, and cellulose has thermal insulation, the outstanding performance of sound insulation and noise reduction; Basalt fibre has acid and alkali-resistance, resistance to elevated temperatures, has good intensity, and acid, alkaline matter are had high-strength corrosion resistance; It is grease proofing that the shell fiber has the water of refusing, and airing function is good; In technology, add magnesium chloride and magnesia, utilize magnesium chloride and magnesian chemical physical property, magnesium chloride is soluble in water; And magnesia is water insoluble; Fire-resistant and insulating properties are highly arranged, make the light cellular partition board of production, have stronger fire resistance and water resistance; In technology, add glass fabric, make the light cellular partition board of production, have advantages such as quality is good, intensity is high, anti-pulling force is strong; In technology, add plastic foamboard, make the light cellular partition board of production, have the heat insulation function of heat preservation and soundproof; Rice wheat straw adds and produces in the light cellular partition board as a kind of novel inserts, has not only reduced the cost that sheet material is made, and reaches the effect of environmental protection simultaneously.
The invention has the beneficial effects as follows: this light cellular partition board has in light weight, and sound-insulating and heat-insulating and waterproof and dampproof property performance are good, and fire line is strong, and intensity is high, and good toughness is saved operation, the reduction of erection time.Adopt rice wheat straw as making this light cellular partition board material main filler, reduced the burning straw pollution on the environment, turn waste into wealth; Added value is high; With low cost, reduced the cost that this light cellular partition board is made, preserve the ecological environment; Benefit the nation and the people, for economy type is created by China, low-carbon (LC) society contributes.
