Abstract
The present invention relates to actylic resin, and especially water base type cationic actylic resin adhesive and its preparation process. The water base type cationic actylic resin adhesive consists of water thinned cationic actylate resin in 75-90 weight portions and water thinned natural or synthetic cationic or non-ionic polymer solution. The cationic emulsifier is polynary copolymer emulsion including N, N'-dimethyl amino ethyl acrylate, butyl acrylate, styrene, 2-ethyl hexyl acrylate, etc. Compared with available technology, the present invention has the advantages of raised adhesion, raised waterproof performance, no toxicity and environment friendship, and is especially suitable for use in finishing household, office, etc.
Description
Technical field
The invention belongs to the light industry chemical technology field.Relate to acrylic resin, specifically water base type cation acrylic resin adhesive and preparation method thereof.
Background technology
Tackiness agent generally is divided into solvent-borne type and aq. type two big classes.Clearly there is contaminate environment in Solvent Adhesive, the ill effect of harm health of human body.Again the energy is caused huge consumption.Not only improved cost especially to the irreversible loss of the limited energy in the human world.As the urea formaldehyde resin adhesive that generally uses at present, aerodux etc., they are not only and contain a certain amount of unreacted formaldehyde the person is caused damage, and constantly discharge formaldehyde cause the persistent infringement of the person in weathering process.Polyvinyl formal tamanori for example is commonly called as 107 glue again, and its cost is low, and bonding effect is good, but this tamanori contains a large amount of free formaldehydes, in use is discharged in the environment, makes the people feel to have the sensation of pungent, peppery eye, directly influences the health of human body.
It should be a kind of environmentfriendly products that one of current tackiness agent of advocating, polyvinyl acetate (PVA) water emulsion are used for bonding wood materials, but it exists two outstanding defectives.The one, its bounding force is less; The 2nd, absorb water and seriously cause adhesion failure.
Summary of the invention
Problem to be solved by this invention is to overcome above said shortcoming with not enough, and environmental protection, nontoxic, water-base cation acrylic resin adhesive that bounding force is strong are provided.
The water-soluble cationic acrylate polymer emulsion of this invention, bondingly again some positively charged ion or the non-ionic polymer aqueous solution are mixed with it in order to be applicable to, thereby obtained can be used for the bonding and WATER REPELLENT of timber, paper, leather and some synthetic materialss.
In order to produce the cationic acrylate polymer emulsion, essential first synthetic macromolecule cationic emulsifier.This emulsifying agent is the quaternised multi-copolymer emulsion of vinylformic acid NN ' dimethylamino ethyl ester, butyl acrylate, vinylbenzene, 2-EHA etc.
The aqueous solution with cationic emulsifier is emulsifying agent, is initiator with the hydrogen peroxide, is that main body is carried out letex polymerization with esters of acrylic acid and some other vinyl monomers, can obtain the water-soluble cationic acrylate polymer emulsion.
The present invention is achieved by the following technical programs:
Water base type cation acrylic resin adhesive of the present invention, it mainly is made up of 75-90 part waterborne cation acrylate resin and 10-25 part waterborne nature or synthetic positively charged ion or non-ionic macromolecular solution, and wherein the waterborne cation acrylic resin is composed as follows:
Cationic emulsifier 25-45 part
2-EHA 15-25 part
Butyl acrylate 8-15 part
Vinylbenzene 30-50 part
Wherein, described cationic emulsifier is composed as follows:
Vinylformic acid NN ' dimethylamino ethyl ester 20-35 part
Vinylbenzene 60-78 part
Butyl acrylate 10-25 part
Vinylbenzene of the present invention can also adopt iso-butylene or compounds such as vinyl cyanide or vinyl toluene, ethyl styrene to substitute.
Waterborne nature of the present invention or synthetic positively charged ion or non-ionic macromolecular material comprise common starch, cationic starch.
The feature and the detected result of water base type cation acrylic resin adhesive of the present invention are as follows:
Second-order transition temperature 9.9-15 ℃
Viscosity 35-80 second (Ge Shi viscosity)
The solid content of tamanori is greater than 30%
The content of organic volatile is less than 1%
Compression shear strength .Mpa, dry strength 9.8
Tackiness agent of the present invention compared with prior art has following advantage and significant positively effect:
1, improved bounding force.Show the negative electricity behavior such as natural fiber class base materials such as timber, paper more.Obtain good bounding force with the bonding certain energy of resin cation (R.C.).
2, improved water resistance, the cation constituent of resin cation (R.C.) in case and the fiber of negative electric charge combine, the hydrophobic part of the resin that will dissociate, thus obtain the excellent waterproof effect.
3, it is bonding lasting that acrylic resin has good ageing-resistant performance assurance.
As tackiness agent, for low cost, more in order to improve initial bonding strength, this cationic binder can add cheap cation high molecular material for example, cationic starch.
Water-base cation acrylic resin adhesive of the present invention can make the paper fiber waterproof, but do not influence the ventilation property of paper fiber, be particularly suitable for the interior decoration of newly tame finishing, office, public place, make people when life, work, not have the sensation of pungent, peppery eye again, no longer because of the leukemia youngster appears in finishing, thereby the environment space that people are lived is clean more.
