Abstract
The present invention relates to a kind of environment-protecting lignin five-resisting adhesive formed from lignin mucilage, adhesion promoter, fire-resisting agent, filling material and water. Said invention is characterized by that its adhesive composition is composed of (wt%) 30%-40% of lignin, 2%-5% of polvinyl alcohol, 4%-8% of polyamine phosphate, 2%-8% of starch, 1%-2% of dipentene and the rest is water. Said adhesive can be used for fibre plate and veneer board, and does not produce the harmful substances of formaldehyde, etc.
Description
Technical field
The present invention relates to a kind of tackiness agent, particularly a kind of environment protective lignin flame redardant adhesive agent.
Background technology
Widely used fiberboard in building materials at present, aerodux in the clamping plate is with phenol, formaldehyde is raw material, along with fiberboard in people's house decoration, a large amount of uses of clamping plate, from fiberboard, free formaldehyde can be distributed to indoor in the clamping plate, and phenol, formaldehyde is harmful and possible carcinogenic to HUMAN HEALTH when manufacturing tackiness agent, because fiberboard, the free formaldehyde volatilization cycle in the clamping plate is extremely long, re-use after making its volatilization after can't be before use, therefore press for a kind of phenol that do not contain, the environment-friendly type tackiness agent of formaldehyde composition is used for fiberboard, the making of clamping plate.
Summary of the invention
The objective of the invention is to solve in the prior art that the aerodux in widely used fiberboard, the clamping plate contains a large amount of formaldehyde in the building materials, the formaldehyde volatilization cycle in fiberboard, the clamping plate is extremely long, re-use after can't making its volatilization before use, after the free formaldehyde emission was extremely indoor, human body sucked the problem of meeting insalubrity for a long time.The present invention designs environment protective lignin flame redardant adhesive agent, it is characterized in that: by xylogen mucus, tackifier, fire retardant, stopping composition and water are formed, it is characterized in that: constitute xylogen 30% by following constituent and weight percent---40%, polyvinyl alcohol 2%---5%, polyphosphoric acid amine 4%---8%, starch 2%---8%, kautschin 1%---2%, surplus is a water.Advantage of the present invention is to use the tackiness agent in fiberboard, clamping plate need not contain the toxic substance industrial chemicals to come synthetic resin binder, thereby can not produce objectionable impurities such as formaldehyde, the health of protection human body.Below in conjunction with embodiment the present invention is elaborated,
Embodiment is got 40 kilograms in xylogen, add 37 kilograms in water and under 80 ℃ condition, put into the reactor dilution, put into 5 kilograms of polyvinyl alcohol again, 8 kilograms of polyphosphoric acid amine, 8 kilograms of starch, 2 kilograms of kautschins, mixing and stirring, can in preparation, add a little sodium hydroxide and regulate pH value,---in 25% the ratio adding fiberboard substrate, at 180 ℃---hot-forming after 5 minutes under 220 ℃ the condition, temperature is below 180 ℃ with 15% with above-mentioned tackiness agent, the thermofixation reaction of xylogen is insufficient, and temperature can make xylogen worsen more than 220 ℃.Also above-mentioned tackiness agent can be directly used in the bonding hot-forming making of wooden splint, and the polyphosphoric acid amine in the tackiness agent there is fire-retardant effect.
Claims (2)
1, environment protective lignin flame redardant adhesive agent is characterized in that: by xylogen mucus, and tackifier, fire retardant, stopping composition and water are formed,
2, by the described environment protective lignin flame redardant adhesive agent of claim 1, it is characterized in that: constitute xylogen 30% by following constituent and weight percent---40%,
Polyvinyl alcohol 2%---5%,
Polyphosphoric acid amine 4%---8%,
Starch 2%---8%,
Kautschin 1%---2%
Surplus is a water.
