Description
Technical field
The present invention relates to material of construction material technical field, plant fiber-cement composite strip plate being specifically related to a kind of resistance to chemical attack and preparation method thereof.
Background technology
Since entering the nineties, in the selection of living environment, people have been not content with general has it to occupy, but is pursuing material of construction and the new building materials of environmental harmony type with natural characteristic.Environmental harmony type building materials must meet heat preservation energy-saving, sound absorption sound insulation, water-proof fire-retardant, nonpoisonous and tasteless, lightweight, the characteristic such as high-strength, safe, plant fiber-cement composite strip plate is exactly a kind of novel environmental harmony type material of construction, selected vegetable fibre refers to annual fiber, mainly refers to that agricultural crop straw is as corn stalk, straw, cotton stem, waste of flax etc.
At China's yearly plant abundance, be inexhaustible, nexhaustible raw material, their lifetime is shorter, does not have too large purposes after withered.These agricultural crop straws through cut off hammer broken after obtained vegetable fibre feature be that length-to-diameter ratio is large, specific tenacity is high, specific surface area is large, density is low and biodegradable, have that cost is low, tensile strength advantages of higher in addition, replace timber to make cementitious composite batten strongthener, in use unharmful substance and obnoxious flavour generate.
But the alkaline attack effect of vegetable fibre extract to the anticoagulation of cement and cement-hydrate all limits the application of plant fiber-cement composite strip plate, show: the high alkalinity liquid phase in cement matrix hole has erosion action to vegetable fibre, thus affects the weather resistance of composite strip plate; Vegetable fibre has very high water-intake rate, the declining to a great extent of flexural tensile strength and Young's modulus after volume change can be caused to cause plant fiber-cement composite strip plate to make moist, and composite strip plate is distorted distortion, even ftractures; Vegetable fibre because there is depolymerization, making its polymerization degree decline and causing the corresponding reduction of its tensile strength under microbial process.For solving the problems of the prior art, need to carry out modification to existing plant fibre surface and reduce the alkalescence of gelling material.
Summary of the invention
Object of the present invention plant fiber-cement composite strip plate being just to provide a kind of resistance to chemical attack and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of plant fiber-cement composite strip plate of resistance to chemical attack, it is characterized in that, be made up of the raw material of following weight part: vegetable fibre 23-33, xylon 13-16, silicate cement 33-38, silica flour 10-14, flyash 40-45, zinc oxide 0.4-0.8, calcium chloride 0.2-0.5, barium mahogany sulfonate 0.1-0.3, elastomeric propylene yogurt liquid 14-18, polychloroprene latex 8-12, tung oil 3-5, water are appropriate.
The preparation method of the plant fiber-cement composite strip plate of described a kind of resistance to chemical attack, is characterized in that comprising the following steps:
(1) vegetable fibre, xylon are put into 105 DEG C drying for baking oven about 3-4 hour, room temperature is dried, rap that to remove to pectin and be crushed to diameter be 3-6mm again with skin hammer, being placed on mass concentration is soak 24 hours in the elastomeric propylene yogurt liquid of 10%, press dry post-drying, air blast to the state of seething sprays into vaporific tung oil, dries;
(2) silica flour is calcined 1-2 hour at 580-690 DEG C, cooling adds flyash agitation grinding 30-40 minute, adds zinc oxide and is warming up to 180-270 DEG C of stirring 5-10 minute, be cooled to 50-80 DEG C, add polychloroprene latex to continue to stir 3-5 minute, be cooled to room temperature, dry porphyrize;
(3) calcium chloride be dissolved in water and stir 10-15 minute, add step (1), (2) reaction mass stirring and evenly mixing, add silicate cement and other remaining components again and stir 20-30 minute, it is shaping to add forming machine, obtains finished product successively after 20-30h through cutting, the demoulding, natural curing.
The present invention has following beneficial effect: it is easy that the present invention prepares simple operations, first elastomeric propylene yogurt immersion stain treatment process is taked to make the surfaces externally and internally of vegetable fibre be enclosed with one layer of polymeric film to plant fibre surface pre-treatment, spray vaporific tung oil again, make whole fibre dense and obtain certain rigidity, and water tolerance improves; Secondly flyash is added and in addition modification replaces part of cement, the growing amount of calcium hydroxide after minimizing aquation, improve the corrosion resistance of vegetable fibre, choose the water cement ratio of 0.42 simultaneously, obtained plant fiber-cement composite strip plate moderate strength, has resistance to chemical attack, insulation, sound insulation, can carry out following closely, saws, twists the mechanical workouts such as wood screw.
