Embodiment 1

[0024] 1. Acrylate modified white latex (26% solid content) is prepared by the following components using the vinegar-acrylic emulsion polymerization process:

[0025]

[0026]

[0027] The specific preparation method of acrylate modified white latex: the first part: first dilute sodium acetate with 4kg water into sodium acetate solution for later use; dilute sodium dodecylbenzenesulfonate with 8kg water into solution for later use; 60kg of water was diluted into a solution for later use; the mixed monomer was composed of acrylic acid, methacrylic acid, methyl methacrylate and vinyl acetate, and the total weight was recorded as 100%, which was added to the system in two proportions;

[0028] The second part: Add 668kg deionized water into the polymerization reactor, add polyvinyl alcohol 1788 while starting to stir, slowly raise the temperature to 88-92°C, and keep the temperature constant for 20-30min. When the temperature is lowered to 60°C, add emulsifier OP-10, sodiu...

Embodiment 2

[0036] A kind of wallpaper mural glue, its preparation method is the same as embodiment 1, difference is that formula is:

[0037]

Embodiment 3

[0039] A kind of wallpaper mural glue, its preparation method is the same as embodiment 1, difference is that formula is:

[0040]

[0041] The mobile performance of this product is mainly achieved through the application of starch in the formula; the level of bonding strength is achieved by adding acrylate modified white latex. The methyl methacrylate in the formula can improve the permeability of the adhesive and improve the adhesive strength. product bond strength.

[0042] The whole process of production and packaging of this product is aseptic operation. The solid content of the product is 19%-19.5%. This product has good freeze-thaw stability. It is frozen at -35°C for 24 hours and thawed at room temperature. After 3 cycles, there is no agglomeration or flocculation. The construction is convenient, and the pasting of wallpaper and murals is beneficial to the mosaic seam; the bonding strength is high, and the wallpaper and murals will not warp or fall off after pasting...

Abstract

The invention belongs to the field of auxiliary adhesives in wallpaper and wall cloth industry and in particular relates to a wallpaper mural adhesive and a preparation method of the wallpaper mural adhesive. The wallpaper mural adhesive is prepared by gelatinizing, cross-linking, complexing, adhesive mixing and reacting of the following raw materials in parts by weight: 66-68 parts of deionized water, 10-12 parts of waxy modified starches, 2-3 parts of cross-linking etherified starch, 2.0-2.5 parts of carbamide, 0.08-0.1 part of a stabilizing agent, 19-21 parts of acrylate modified white latex, 0.1 part of a defoaming agent, 1-1.2 parts of glycerol and 0.25 part of a bactericide. Two modified starches are gelatinized, cross-linked, complexed and reacted to form glutinous rice glue; the glutinous rice glue is mixed with the acrylate modified white latex to modify adhesion performance and form mural adhesive. The wallpaper mural adhesive can be used for pasting thick and heavy wallpaper, paper cloth and mural.

Description

technical field [0001] The invention belongs to the field of auxiliary material adhesives in the wallpaper and wall covering industry, and in particular relates to a wallpaper mural adhesive and a preparation method thereof. Background technique [0002] Glutinous rice wet glue is often used for paste construction of wallpaper and wall coverings. Glutinous rice wet glue is mixed with water at a ratio of 1:1. There are certain difficulties. Contents of the invention [0003] In order to solve the problem that the domestic mural paste needs to ensure the bonding strength and meet the frequent movement of flowers during the mural construction period, the present invention provides a kind of wallpaper mural glue, which can be used to paste heavy wallpaper, wall covering and mural, construction Convenient and effective. [0004] The invention also provides a preparation method of the wallpaper mural glue. [0005] The technical solution adopted by the present invention to so...
