Embodiment 1

[0042] Take 35 parts by weight of vegetable meal, 10 parts by weight of alkaline material, 8 parts by weight of calcium oxide, and 105 parts by weight of deionized water.

[0043] Calcium hydroxide milk is obtained by mixing calcium oxide with an equal amount of deionized water and aging;

[0044] Add the above components and the remaining amount of deionized water into the degradation tank, stir and heat up to 50-100°C to make a degradation solution;

[0045] Finally, add 10 parts by weight of urea, 5 parts by weight of alkyl sodium sulfate, and 2 parts by weight of inorganic acid solution into the degradation solution, mix and stir, keep the temperature at 50-100°C, and react for 3-5 hours. Store the product cooled to room temperature.

Embodiment 2

[0047] Take 32 parts by weight of vegetable meal, 12 parts by weight of alkaline material, 10 parts by weight of calcium oxide, and 99 parts by weight of deionized water.

[0048] First, 10 parts by weight of calcium oxide and 5 parts by weight of deionized water are mixed and matured into calcium hydroxide milk;

[0049] Add the above-mentioned components and the remaining water into the degradation tank, stir and heat up at 50-100°C to make a degradation solution, add 12 parts by weight of urea, 7 parts by weight of alkyl sodium sulfate, and 3 parts by weight of inorganic acid solution Mix and stir the degraded mixed liquid, keep the temperature at 50-100° C., and react for 3-5 hours. The degraded and modified product is cooled to room temperature and stored.

Abstract

The invention relates to a formaldehyde-free environment-friendly vegetable protein modified adhesive, which aims to solve the problem that the prior urea-formaldehyde adhesive, phenolic aldehyde adhesive and melamine aldehyde adhesive release formaldehyde and cause environmental hazard and pollution, etc. The compositions in portion by weight of the modified adhesive are: 30 to 50 portions of natural plant dregs, 5 to 12 portions of basic material, 5 to 10 portions of calcium hydroxide emulsion, 6 to 15 portions of urea, 4 to 10 portions of alkyl sodium sulfate, 2 to 5 portions of 10 to 20 percent of inorganic acid and 90 to 120 portions of deionized water. The invention takes macromolecular proteins in natural plant soybean dregs, peanut dregs, rapeseed dregs, cottonseed dregs, linseed dregs and sunflower seed dregs as raw materials so as to synthesize a new-generation formaldehyde-free environment-friendly vegetable protein modified adhesive through chemical modification. The formaldehyde-free environment-friendly vegetable protein modified adhesive has the characteristics of uniform and stable product, high adhesion strength, hydrolysis resistance and nontoxicity, etc.; moreover, the performance and the price of the modified adhesive are suitable for wood adhesion and for making artificial fiber boards such as plywood, shaving board and fiber board.

Description

technical field [0001] The invention relates to a formaldehyde-free and environment-friendly plant protein modified adhesive, which solves the problem that the existing wood industry urine-aldehyde glue, phenolic glue, melamine-aldehyde glue and the like cause harm to the environment due to the release of formaldehyde. The present invention uses natural plant soybean meal, peanut meal, rapeseed meal, cottonseed meal, linseed meal, sunflower meal, etc. as raw materials to synthesize a new generation of water-based formaldehyde-free vegetable protein through degradation and chemical modification. adhesive. It is non-toxic and water-resistant. The bonding strength is higher than that of traditional urea-aldehyde adhesives, meeting the most stringent international testing standards for formaldehyde emissions. It is suitable for the production of plywood, particleboard, fiberboard and other wood-based panels and the bonding of wood. Background technique [0002] At present, th...
