Description
Technical field
The invention belongs to based Wood Adhesives technical fields more particularly to a kind of based on just glutinous agent modified double components dregs of beans glue
The preparation and its application on I class glued boards of glutinous agent, have preferable tack, coating, mobility and physical mechanics property
Energy.
Background technology
According to statistics, the yield of global wood adhesive in 2015 accounts for the 3/4 of adhesive total output, in recent years, China's glue
Glutinous agent industry and industry of artificial boards are quickly grown, and have been the big production and consumption big country of the first in the world at present.2015, Chinese people
Plate yield is made as 30212.33 ten thousand steres, and the annual situation for keeping sustainable growth.Above statistics shows to process with timber
The sustained and rapid development of industry, the dosage of wood adhesive are increasingly increasing, and the output of wood adhesive has become measurement one
The important symbol of a country timber industry state-of-art height.
The advantages that soybean is high with its resource abundance, yield, and plant protein content enriches, makes it as material preparation biomass
Adhesive becomes a kind of inexorable trend.Soy protein adhesives be with soybean protein isolate, soy protein concentrate, defatted soy flour and
Bean cake powder is primary raw material, and soybean protein is modified by technological means such as physics, chemistry, biologies, a kind of ring of preparation
Border friendly biomass adhesive.The one kind of bean cake powder as by-products of soybean, at low cost, protein content is moderate, containing active group
Group is more, can preferably meet the basic demand of biomass adhesive.By being modified to bean cake powder, to obtain cohesiveness strong, resistance to
Aqueous strong, environmental protection biomass adhesive meets the market needs of current environmentally friendly adhesive.However unmodified soybean
Protein adhesive, bonding strength is low, and water resistance is poor, and the Hydrogenbond formed between timber interface can only generate good dry
State intensity, and wet strength is then very poor.Therefore, water resistance based Wood Adhesives are manufactured with soybean protein, it is necessary to soybean protein
Reinforcing is modified, is improved and hydroxyl (- OH), amino (- NH in protein molecule2), carboxyl (- COOH) and sulfydryl (- SH) etc.
The reaction of active function groups generates water-fast chemical bond, forms compact-sized mesh skeleton, and hydrone is prevented to enter to hydrogen bond
It damages, and then improves the water resistance of adhesive.Soybean protein base adhesive has preferable market prospects, related modified soybean
The research of albumen adhesive is more, but it is undesirable to promote and apply present situation.The soybean base adhesive prepared at present contains low, viscosity admittedly
Greatly, poor mobile performance, it is difficult to substitute cheap aldehyde system adhesive completely.Moreover, its application on wood-based plate is mostly used in
Indoor type wood-based plate makes, it is difficult to meet the requirement of outdoor version wood-based plate.In existing dregs of beans adhesive technology of preparing, gluing
The viscosity of agent, contain admittedly, water resistance, coating performance etc. also need to further improve, technique for applying still needs to further optimize.
The content of the invention
The technical issues of solution：For solve conventional petroleum chemical industry adhesive not environmentally, the non-renewable and potential formaldehyde of resource
Release problem, it is poor to break through traditional biomass adhesive adhesive tack, poor fluidity, difficult coating, large viscosity, poor water resistance,
The application technology bottlenecks of the defects on wood-based plate such as bonding strength is low, the present invention propose a kind of based on just glutinous agent modified double components
The preparation of dregs of beans adhesive and its application on I class glued boards possess Storage period length, property is stable, tack is good, mobility
The advantages that good, property easy to apply and good permeability, the glued board of preparation can meet requirement of the country to I class glued boards.
