Abstract
The adhesive in the invention mixes innocuous and aldehyde-free organic liquid adhesives such as polyvinyl alcohol and polyvinyl acetate with cheap waterproof inorganic solid adhesives in use, which is used for the nuisanceless cold-pressed production of the artificial boards. The invention has the virtues of simple processing, low cost, environmental protection and energy saving etc.
Description
The invention belongs to a kind of production method of novel pollution-free, fast-drying aqueous tackiness agent, be applied to Wood-based Panel Production and can realize the production of colding pressing of nuisancelessization of wood-based plate.
At present, construction and decoration, furniture, industries such as wood-based plate, a large amount of tackiness agent that contain toxic substances such as formaldehyde that use, environment is caused severe contamination, cause people's the worry and the attention of country day by day, environmental regulation according to the up-to-date appearance of country, prohibited the various poisonous glue paste that uses the formaldehyde resultant to exceed standard or environment is had pollution, but nontoxic aldehyde-free cement is not on the high side, be that adhesive effect is undesirable, make most of small enterprises be difficult to accept, some is titled with the product of " no-formaldehyde adhesive ", its main raw material still is a formaldehyde, just improves by various technical matters, free formaldehyde content in the goods is reduced, along with envrionment temperature, climate change, still can discharge toxic gas, the harm health of people! And " three aldehyde " glue belongs to hot setting adhesive, must be heated to about 120 ℃, could completely solidified, and energy consumption is very big.
The present invention seeks to develop a kind of novel aldehyde-free cement, absolutely do not contain toxic substances such as formaldehyde, especially price and Precondensed UreaFormaldehyde Resin are close, and accepted by the user, and need not hot pressing and can realize the production of colding pressing of nuisancelessization of wood-based plate, thereby it is seriously polluted to change present wood-based plate industry, the severe situation that energy consumption is huge.Can be widely used in industries such as wood-based plate and furniture finishing.
Method of the present invention is that organic polymer and price that adhesiveproperties is good is low, and the mineral binder bond of water-tolerant mixes mutually, has complementary advantages.The polymkeric substance of selecting for use is the lower polyvinyl alcohol of price, polyvinyl acetate, ethene---vinyl acetate, water-base resins such as the aminoresin of modification, and mineral binder bond mainly is various cement, is good with the silicate cement that contains tricalcium silicate and Dicalcium Phosphate (Feed Grade) mixture; Semi-hydrated gypsum or dehydrated gyp-I and dehydrated gyp-II and be good with semi-hydrated gypsum.The present invention is used for Wood-based Panel Production, can form two components, with the organic polymer liquid adhesive as one group, the inoganic solids binding agent is organized as another, in use, better by the interim effect that adds of prescription.
Main prescription of the present invention (by mass percentage):
(1) polyvinyl alcohol 0-8%, polyvinyl acetate or ethane-acetic acid ethyenyl or its mixed latex (solid content 50%) 10%-40%, properties-correcting agent is an amount of, thickening material is an amount of, water 55%-88%; Cement or gypsum and retardant thereof or exciting agent be 3%-25% (this solid inorganic binding agent can independent a group, temporarily add in use) altogether.
(2) polyvinyl alcohol 5%-11%, properties-correcting agent are an amount of, water 65%-88%; Cement or gypsum and retardant thereof or exciting agent be 5%-25% altogether, (this inorganic component can independent one group, add in use) temporarily.
(3) polyvinyl alcohol 1%-7%, hydrolyzed starch 5%-30%, water 60%-88%; Cement or gypsum and retardant 3%-20% thereof (this inorganic component can independent one group, add in use) temporarily.
(4) through the Precondensed UreaFormaldehyde Resin or the melamine formaldehyde resin of modification, or water-soluble phenolic resin adhesive (solid content equal about 45%) 5%-25% (this component and solidifying agent can independent a group, temporarily add in use).
The present invention compares with similar tackiness agent in the market, (prescription 4 adopts Precondensed UreaFormaldehyde Resin or the melamine resin or the water soluble phenol resin that can reach the above modification of environmental protection E2 level to have toxic substances such as not containing formaldehyde, after adding solidifying agent and gypsum, can further reduce the goods free formaldehyde content) to produce and environment for use is pollution-free, cost is low, technology is simple, adhesive effect is good, drying solid speed soon, be used for Wood-based Panel Production, need not hot pressing energy-saving effect remarkable advantage.
