Description
Technical field
The present invention relates to the technical fields of wall paper auxiliary material, more particularly, to a kind of wall paper basement membrane and its preparation process.
Background technique
Wall paper basement membrane is a kind of novel wall surface processing material matching used when wall paper is pasted.Before wall paper stickup,
Metope coats one layer of wall paper basement membrane, it just can form one layer of fine and close protective film in metope, prevents moisture content and alkaline matter from exosmosing,
Effectively extend the service life of wall paper, while providing convenience for the replacement of the later period of wall paper.The application method of wall paper basement membrane is very simple:
Using the roller of roller coating material, equably by basement membrane roller coating on metope, after basement membrane is dry, wall paper is sticked.
Currently, wall paper basement membrane in the market is generally made of polyaminoester emulsion, but polyaminoester emulsion is after a long time placement,
, there is solidification, condense into the problems such as paste in reduction and the reaction of bandage Cross-linked due to moisture.After long-time is placed, meeting
Condense into paste.Therefore, for being diluted with water with the wall paper basement membrane after prolonged place, being allowed to be formed uniform
After stable solution, just it can be used.But after being diluted with water, causes the solution density of the basement membrane when smearing to reduce, lead to wall
Caking property between cloth and metope is not high, is easy to separate with metope.
Summary of the invention
The object of the present invention is to provide a kind of wall paper basement membrane and its preparation processes, pass through acrylic emulsion and polyaminoester emulsion
Compounding, and be added have thickener, avoid wall paper basement membrane due to long-time place and solidify, and can be improved wall paper basement membrane and
Caking property between metope.
Foregoing invention purpose of the invention has the technical scheme that
A kind of wall paper basement membrane, including following raw material: the first 365-385 parts of auxiliary agent, 16-20 parts of coalescing agent, second
16-20 parts of glycol, 1-5 parts of wetting agent, 1-5 parts of defoaming agent, 18-32 parts of thickener and 545-565 parts of deionized water；
