Abstract
The invention discloses vinyl-acrylic emulsion and a preparation method thereof. The vinyl-acrylic emulsion is prepared by mixing and reacting vinyl acetate, polyvinyl alcohol, butyl acrylate, ethylenediamine tetraacetic acid, carbonate, methanol, acrylic acid, an ammonium persulfate solution, dibutyl phthalate, an emulsifier and deionized water which are used as raw materials. The vinyl-acrylic emulsion is high in strength and high in drying speed. The vinyl-acrylic emulsion serves as an adhesive of furniture, plywoods and wood products, and the product quality and the production efficiency can be improved.
Description
Technical field
The present invention relates to a kind of glue and preparation method thereof.Specifically, be furniture, glued board, timber caking agent, also can be used for the high viscosity emulsion that coating material production is used.
Background technology
At present, the caking agent using in furniture, glued board, timber-work production process is all conventional adhesive.This conventional binders, intensity is low, rate of drying is slow, adopts this binding agent, be not only difficult to improve the quality of products, and production efficiency is low.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of vinyl-acrylic emulsion.This vinyl-acrylic emulsion, intensity is high, and rate of drying is fast.Binding agent with this vinyl-acrylic emulsion as furniture, glued board, timber-work, can improve product quality and production efficiency.
For addressing the above problem, the present invention takes following technical scheme:
Vinyl-acrylic emulsion feature of the present invention is the raw material that contains following weight fraction:
Rare 18 ~ 22 parts of acetic acid second;
4 ~ 5 parts of polyvinyl alcohol;
3 ~ 5 parts of butyl acrylates;
0.01 ~ 0.02 part of sodium ethylene diamine tetracetate;
0.05 ~ 0.10 part, carbonate;
0.1 ~ 0.3 part of methyl alcohol;
0.1 ~ 0.3 part, vinylformic acid;
1 ~ 3 part of ammonium persulfate solution;
1 ~ 2 part of dibutyl phthalate;
0.1 ~ 0.2 part of emulsifying agent;
20 ~ 30 parts of deionized waters.
The feature of preparing the method for described vinyl-acrylic emulsion is to comprise the following steps successively:
First deionized water, polyvinyl alcohol be mixed together and at room temperature react 25 ~ 30 minutes; Afterwards, heat to 90 ~ 100 ℃, and keep 50 ~ 70 minutes at this temperature;
Afterwards, be cooled to 50 ~ 55 ℃, add emulsifying agent and methyl alcohol, stir 5 ~ 10 minutes;
Afterwards, add 10% vinyl acetate between to for plastic, stir 10 ~ 20 minutes, make emulsifying materials;
Afterwards, add 1/2 ammonium persulfate solution, at 50 ~ 55 ℃, react 50 ~ 70 minutes;
Afterwards, material is heated up, in the time that temperature rises to 80 ~ 83 ℃, add remaining vinyl acetate between to for plastic, butyl acrylate, vinylformic acid and ammonium persulfate solution, and be incubated 50 ~ 70 minutes;
Finally, add dibutyl phthalate, and be cooled to normal temperature, obtain vinyl-acrylic emulsion.
Take such scheme, have the following advantages:
As can be seen from the above scheme, due to polymerization reaction at 90 ~ 100 ℃ in early stage of the present invention, can make reacting balance carry out.Make the present invention there is the performance that intensity is high, rate of drying is fast.Binding agent with this vinyl-acrylic emulsion as furniture, glued board, timber-work, can improve product quality and production efficiency.
