Abstract
The invention discloses a novel non-formaldehyde environment-friendly adhesive and a preparation method. The novel non-formaldehyde environmentally-friendly adhesive is formed by proportionately charging, cross-linking and polymerizing sclerotin protein, sodium hydroxide, sodium benzoate and catalysts, and has the characteristics of water resistance, weather resistance, mould prevention, environmental friendliness, and the like. The formaldehyde release amount of a special decorative board manufactured by using the adhesive is only 0.1mg/L, which is lower than 0.5mg/L required by a national standard as well as 0.2mg/L required by European and American standards, so that the novel non-formaldehyde environment-friendly adhesive can be widely applied to woodwork industries such as artificial boards, furniture and composite floors.
Description
Technical field:
The present invention relates to a kind of novel formaldehyde-free environment-friendly adhesive and preparation method, can be widely used in the Wood Products Industries such as wood-based plate, furniture, composite floor board, there is the characteristics such as water-fast, weather-proof, mildew-resistant, environmental protection.
Background technology:
Current China Wood Products Industry sticks with glue agent and take " three-aldehyde glue " as main, account for whole Wood Products Industry and stick with glue the more than 85% of agent, but such adhesive made of synthetic resin continuous release formaldehyde of meeting in production and use procedure brings environmental pollution, is detrimental to health.In recent years, along with the expansion of Market of Adhesives, problem of environmental pollution is day by day subject to people and pays close attention to, and more and more higher to the requirement of environmental protection, the demand of novel environment friendly tackiness agent is more and more higher.
Summary of the invention:
The object of the invention is, the shortcoming according to existing Wood Products Industry with traditional tackiness agent formaldehyde pollution, researchs and develops a kind of environment-friendly adhesive and preparation method of novel formaldehyde-free.
Technical scheme of the present invention is, this novel formaldehyde-free environment-friendly adhesive is formed by sclerotin albumen, sodium hydroxide, Sodium Benzoate and the catalyst by proportion crosslinking polymerization that feeds intake.
Its preparation method is: in appropriate water, add high-molecular polyivnyl alcohol 50-60% to heat to 90 ℃ of dissolvings, be cooled to 60 ℃ and add acrylate 20-40%, then add catalyzer 0.02-0.05% to be warming up to 95 ℃, add again sclerotin protein 10-20% and rosin fat 10-20%, when reacting about 8 hours and being cooled to 40 ℃, drop into mould inhibitor Sodium Benzoate 0.02-0.05%, stir finished product blowing after half an hour.
It is not water-fast that a kind of novel formaldehyde-free environment-friendly adhesive of the present invention has overcome conventional bone albumin glue, dry slow of glue-line and can not mechanically operated shortcoming, by the combination of sclerotin albumen and rosin fat, high-molecular polyivnyl alcohol, acrylate, improved the bonding strength of sclerotin albumin glue, more than reaching 4 MPas, the advantages such as while tool is water-fast, weather-proof, mildew-resistant, environmental protection, with the house ornamentation special-purpose board burst size of methanal that this tackiness agent is manufactured, be only 0.1mg/L, lower than the 0.5mg/L of national standard, also lower than American-European standard 0.2mg/L.
Embodiment:
Below in conjunction with embodiment, make further instructions.
In appropriate water, add high-molecular polyivnyl alcohol 50% to heat to 90 ℃ of dissolvings, be cooled to 60 ℃ and add acrylate 25%, then add catalyzer 0.04% to be warming up to 95 ℃, add again sclerotin protein 15 % and rosin fat 10%, when reacting about 8 hours and being cooled to 40 ℃, drop into mould inhibitor Sodium Benzoate 0.03%, stir finished product blowing after half an hour.
Claims (1)
1. a novel formaldehyde-free environment-friendly adhesive preparation method, it is characterized in that adding high-molecular polyivnyl alcohol 50-60% to heat to 90 ℃ of dissolvings in appropriate water, be cooled to 60 ℃ and add acrylate 20-40%, then add catalyzer 0.02-0.05% to be warming up to 95 ℃, add again sclerotin protein 10-20% and rosin fat 10-20%, when reacting 8 hours and being cooled to 40 ℃, drop into mould inhibitor Sodium Benzoate 0.02-0.05%, stir finished product blowing after half an hour.
