(54) ПРЕСС-МАССА ДЛЯ ИЗГОТОВЛЕНИЯ ДРЕВЕСНОСТРУЖЕЧНЫХ ПЛИТ(54) PRESS MASS FOR THE MANUFACTURE OF WOOD-BODY PLATES
II
Изобретение относитс к строительным материалам и предназначено дл изготовлени др|евесностружечных плит, которые использую как облицовочно-декоративный, теплозвукоизол ционный и конструкционный материал в гражданском, промышленном, сельскохоз йственном , вагонном строительстве, судостроении , а также дл производства мебели.The invention relates to construction materials and is intended for the manufacture of other external boards, which are used as decorative facing, heat and sound insulating and structural materials in civil, industrial, agricultural, car building, shipbuilding, as well as for the production of furniture.
Известна пресс-масса дл изготовлени дре весностружечных плит, включающа измельченную древесину, алюмохромфосфатное св зуюшее , карбамидную смолу, парафиновую эмульсию 1.A known press pulp for making wood chipboards, including crushed wood, aluminum-chromophosphate bonding, carbamide resin, paraffin emulsion 1.
Недостатком ее вл етс то, тго на стадии смешени компонентов смеси, а также при прессовании и в течение длительного времени после изготовлени их происходит выделение вредно действующего на организм человека токсического компонента - формальдегида.Its disadvantage is that at the stage of mixing the components of the mixture, as well as during pressing and for a long time after their manufacture, the toxic component of formaldehyde harmful to the human body is released.
Известна пресс-масса дл изготовлени древесностружечных плит, включающа древесные отходы, карбамидную смолу, фосфатное св зующее и гидрофобную добавку - парафин 21.A known press pulp for the manufacture of chipboard, including wood waste, carbamide resin, phosphate binder and a hydrophobic additive, paraffin 21.
Недостатком зтой пресс-массы вл етс то что плиты, полученные на ее основе, также в течение длительного времени выдел ют формальдегид.The disadvantage of this press mass is that the plates obtained on its basis also formaldehyde are released for a long time.
Цель изобретени - снижение токсичностк плит на ее основе.The purpose of the invention is to reduce the toxicity of plates based on it.
Поставленна цель достигаетс - тем, что пресс-масса дополнительно содержит поливиниловый спирт при следующем соотношении компонентов, вес.%:The goal is achieved by the fact that the press mass additionally contains polyvinyl alcohol in the following ratio of components, wt.%:

Сущность изобретени по сн етс примерами .The invention is illustrated by examples.
Пример 1. 80%.древесной стружки с влажностью 3% смешивают с 18% карбамидной смолы КС-68М (59% конц), 1% фосфатно го св зующего (13% конц.), 0,5% парафина и 0,5% поливинилового спирта (10% конц.). Массу перемешивают 5-7 мин, после чего прессуют в гор чем прессе при температуреExample 1. 80% wood chips with a moisture content of 3% are mixed with 18% carbamide resin KS-68M (59% conc), 1% phosphate binder (13% conc.), 0.5% paraffin and 0.5% polyvinyl alcohol (10% conc.). The mass is stirred for 5-7 minutes, after which it is pressed in a hot press at a temperature of
