Said compound emulsifying agent union base phenol polyethenoxy ether yellow amber hydrochlorate DNS-1035 and polyoxyethylene nonylphenol OP-10 form, and their proportioning is the arbitrary value between 1:2～2:1.
White glue with vinyl of the present invention is carried out modification by copolymerization with vinylformic acid AA and functional remodeling agent Dichlorodiphenyl Acetate vinyl acetate VAC; Reduce the consumption of PVAC polyvinylalcohol; Add W-Gum and functional stopping composition; The tackiness agent of processing not only initial bonding strength and bonding strength has raising in various degree, and product has good low-temperature stability.Product has higher advantage on cost performance, have vast market prospect.The present invention has improved the low-temperature stability of common white glues, has improved the cohesive strength and the sticking power of product, has obviously reduced cost.
In order to realize back one purpose, the present invention also provides a kind of working method of above-mentioned white glue with vinyl, and this method comprises the steps:
(1) in the four-hole bottle that reflux exchanger, TM and tap funnel are housed, adds measured water;
(2) add PVAC polyvinylalcohol while stirring; Slowly being warming up to 90 ℃ kept 30 minutes;
(3) equitemperature is reduced to 75 ℃ then, adds compound emulsifying agent, and 1/3 initiator also begins to drip comonomer, and temperature of reaction is controlled between 75 ℃ ~ 85 ℃, and monomer dripped in four hours, and initiator ammonium persulfate is added in the centre;
(4) drip off monomer insulation for some time, begin cooling and add W-Gum, the control gelatinization point;
(5) insulation adds functional filler, Witcizer 300 after half a hour;
(6) continue cooling and add 10% NaOH and regulate pH value 4～4.5, add sanitas and stir and get final product.
Adopt aforementioned production method, arranging raw material adds order scientifically and rationally, adopts the rational temperature time, utilizes copolyreaction can obtain white glue with vinyl of the present invention.
