Description
The present invention relates to a kind of bonding glue, particularly a kind of water miscible liquid adhesive for locating and manufacture method thereof.
In furniture manufacturing industry, need to use a kind of sponge material and wood bonding liquid adhesive for locating (tackiness agent) together that makes, existing liquid adhesive for locating is non-water-soluble, used organic solvent, cause pollution and workplace air quality deteriorated to environment, the infringement workman is healthy, therefore, people wish to seek a kind of surrogate, replace existing liquid adhesive for locating with the water-soluble liquid adhesive for locating that does not contain organic solvent.
In adhesive field, its Chemical Composition is based on ethene more, or (with) the propylene vinegar, the polymerizing acrylic acid thing.Along with its component and content are different, and the tackiness agent of a multitude of names occurs, and show different results of use.China's " Gazette of Patent for Invention " discloses the patent application of application number 96197414, name is called " use based on ethene; (methyl) propylene vinegar; and (methyl) polymerizing acrylic acid thing applies or sealing panes of laminated safety glass ", employed polymkeric substance composition, comprise A) the ethene B of 30%-90%wt) 0-10%a-alkene, C) 3-40% acrylate or methacrylic ester, D), 7-30% vinylformic acid and/or methacrylic acid, E), the 0-10% copolymerisable monomer, above-mentioned polymkeric substance is used for applying or sealing panes of laminated safety glass, does not relate to other Application Areass.
The purpose of this invention is to provide a kind of contain vinyl polymer, in the furniture manufacturing, be used for adherent, water-soluble sponge liquid adhesive for locating and manufacture method thereof.
Purpose of the present invention can reach by following measure
Liquid adhesive for locating of the present invention is a kind of polymer latex that uses following composition: A) 35-45wt% methyl methacrylate-grafted latex, methyl methacrylate content 35% in this latex, (being commonly called as MG latex); B) ethylene/ethyl acrylate of 17-23wt%/vinyl acetate between to for plastic ternary copolymer emulsion (solid component content 54%, viscosity 1700-2500, pH value 4.0-5.5), C) 4-6wt% casein food grade), D) 1.2wt% zinc oxide, E) 2wt% lower alcohol (ethanol and butanols), F) 0.5WT% dibutyl phthalate, G) 2%wt anti-aging agent three (nonylated phenyl) phosphorous acid ester, and can add other auxiliary agents of 4-8wt%, all the other are water;
Above-mentioned latex also can contain following composition: a) 0.5%wt promotor ethylene thiourea.B), an amount of NaOH solution pH value conditioning agent .e 1.5wt% fat alcohol polyethylene ether .d 0.8wt% glycerine .c))).
Make above-mentioned liquid adhesive for locating and take following technology: according to the component of above-mentioned each component, 1) 10% solution of preparation casein food grade: earlier casein food grade was soaked 6 hours in soft water, add soft water then, progressively heat up and be heated to 60 ℃, stir half an hour, be deployed into 10% casein food grade solution, be cooled to normal temperature with soft water, add percentage composition and be 3% ammoniacal liquor, the pH value of casein food grade solution is adjusted to 10-11;
2) in 10% casein food grade solution, progressively add zinc oxide, ethylene thiourea, be stirred to pasty state, add glycerine then, ball milling 2 hours, to its fineness be 45 microns (um);
3) add anti-aging agent in dibutyl phthalate, for example three (nonylated phenyl) phosphorous acid ester is stirred to pasty state, adds soft water and fatty alcohol-polyoxyethylene ether (being commonly called as " peregal "), fiercely stirs it;
4) be that ethylene/ethyl acrylate/vinyl acetate between to for plastic terpolymer latex solution of 35% methyl methacrylate-grafted latex and solids content 54% adds in the reactor stirring at low speed 30 minutes with content;
5) above-mentioned 4) mixed solution in, add above-mentioned 2) and 3) mixture, the moderate speed stirred 1 hour down;
6) in above mixed solution, add and account for latex total amount 1.5wt% ethanol and account for latex total amount 0.5wt% butanols, stir, toward reacting kettle jacketing in, feed cold water, mixture is lowered the temperature, and stirred 40 minutes;
7) add pH value conditioning agent (AMP-10) and regulate the pH value at 7-10;
8) filter, get white emulsion, the solid content of this finished product 〉=43%, viscosity 500-1000.
The liquid adhesive for locating that adopts above-mentioned technology to make, its dry strength are 3.8Mpa, and minimum film-forming temperature is 5 ℃, has the following advantages; Use under the room temperature, can position with adhesive bonding of wood sponge, leather, cotton etc. about 1 minute, initial bonding strength is strong, and it is big to do solid work intensity.After adhesion coating was done solid work, colourless, transparent, snappiness is good, high resilience was not ftractureed, in-10-60 ℃ temperature range, and glue-line stable performance, good water-proof effect.Because this liquid adhesive for locating does not contain organic solvent, or heavy metal ion, and sticky object is not had corrosion, environment is not polluted.This product is an aqueous emulsion type, and stable storing is nonflammable.Safety non-toxic is to human body toxicological harmless effect.In furniture manufacturing industry, be widely used in bonding to sponge.
