Preparation method of coating for pasting household wallpaper

Abstract

The invention provides a preparation method of a coating for pasting household wallpaper. The coating is prepared from a main binder, an auxiliary binder, filler, a crosslinking agent and a mildewproof agent, wherein the main binder is prepared from polyvinyl alcohol, formaldehyde, ammonium persulfate and sodium bisulfite with a pre-emulsification and semi-continuous emulsion polymerization processes, and the concentration of formaldehyde is 0.37 mol / L; the auxiliary binder is prepared from a water-soluble sodium hydroxide solution with the concentration of 0.3 mol / L; the filler adopts expandable quartz sand particles which are not prone to pulverization; the crosslinking agent is prepared from a benzoyl peroxide material; the mildewproof agent is prepared from an ammonium persulfate material. The main binder is prepared with the pre-emulsification and semi-continuous emulsion polymerization processes, so that adhesion strength of the wallpaper coating is improved effectively, follow-up edge warping is prevented, and by adding the mildewproof agent, edge warping damage under conditions of dampness and bacterial corrosion of the wallpaper due to long use time of the coating is prevented effectively.

Description

technical field [0001] The invention relates to the technical field of wallpaper paint manufacture, in particular to a method for preparing a paint for home wallpaper lamination. Background technique [0002] Wallpaper paint is a special adhesive product for construction that is used to stick wallpaper and is made of polymer extracts. Guaranteeing the stickiness and service life of wallpaper is the most basic function. At the same time, it is also required that the product is environmentally friendly and harmless. You can't pursue environmental protection and ignore stickiness, or pursue stickiness and ignore environmental protection. [0003] However, after the wallpaper is pasted, warping will occur after a period of use. The reasons for warping are divided into two categories. One is construction problems. This link is mainly due to uneven glue application by workers. In the current construction market, after-sales are all solved by the construction workers themselves,...

[0003] However, after the wallpaper is pasted, warping will occur after a period of use. The reasons for warping are divided into two categories. One is construction problems. This link is mainly due to uneven glue application by workers.

In the current construction market, after-sales are all solved by the construction workers themselves, so many workers can avoid uneven glue application during construction, and the other type is the problem of wallpaper coatings. The adhesion of the coatings is sufficient. Use The lifespan is not long, the adhesive force is not enough, and the edges and corners will naturally warp after a long time. Many people have lived in hotels, and often see the wallpaper of the hotel will warp the edges and corners. In fact, it is not because of construction or wallpaper problems, there are many reasons It is all caused by the paint. We all know that the decoration cycle of hotels is shorter than that of home decoration, but this kind of problem still occurs, and the problem lies in the paint.
