Embodiment 1

[0028] A method for preparing wallpaper base film, the specific process is as follows:

[0029] 1) Batching: batching is carried out according to the formula in Table 4.

[0030] Table 4

[0031]

[0032]

[0033] Potassium persulfate 2.2kg is dissolved with 60kg deionized water to obtain an initiator solution, and the total volume of the initiator solution is recorded as 100%, and the system is added in batches during the reaction to avoid the reaction being too violent to produce the phenomenon of cascading;

[0034] Sodium lauryl sulfate 4.5kg is dissolved with 8.6kg deionized water, obtains sodium lauryl sulfate solution;

[0035] Heat and dissolve 12kg of N-methylolacrylamide with 16kg of water to obtain N-methylolacrylamide solution;

[0036] Dissolve 6 kg of sodium hydroxide with 8 kg of deionized water to obtain a sodium hydroxide solution for subsequent use.

[0037] 2) Prepare pre-emulsion:

[0038] Add 160kg of deionized water to the pre-emulsification tan...

Embodiment 2

[0048] A kind of preparation method of wallpaper base film, carry out batching according to the formula of table 4, preparation method is the same as embodiment 1.

Embodiment 3

[0050]A kind of preparation method of wallpaper base film, carry out batching according to the formula of table 4, preparation method is the same as embodiment 1.

Abstract

The invention belongs to the field of wallpaper auxiliary materials and particularly relates to a wallpaper base film and a preparation method thereof. In the prescription of the wallpaper base film, the ratio of the soft monomer to the hard monomer is 43.5:56.5, the requirement of the product on the water tolerance and the hardness can be increased; the volume dose of the crosslinking monomer is 7.8%; the polymerization process of the product is stable; the volume dose of three emulsifiers exceeds 3% and reaches 3.8%; a good operation condition for the pre-emulsification process can be provided; 0.5% of an initiator is adopted, the initiator plays a role in monomer polymerization, and simultaneously promotes the residual monomer to react in a later high temperature stage so that the monomer residue can be reduced, the smell can be eliminated and the product is environmentally friendly; the glycol is added in the prescription so that the freeze-thaw stability and the film-forming ratio of the product can be increased, and a sterilizer is added for preventing the mildew and the deterioration.

Description

technical field [0001] The invention belongs to the field of wallpaper auxiliary materials, in particular to a wallpaper base film and a preparation method thereof. Background technique [0002] The material used for construction base surface treatment in the early stage of wallpaper construction, its main function is to prevent moisture, mildew, alkali, and protect wallpaper and walls. In the early days, the processing material in the industry was mainly "varnish", a kind of synthetic resin. Now it usually refers to the surface transparent varnish, which is made of base materials and additives. , the main components are resin and solvent or resin, oil and solvent. After being applied to the surface of the object, a coating film with protective, decorative and special properties is formed, and the coating film of the varnish is transparent. The main disadvantage of using varnish for wall treatment is that there are many harmful components in the solvent, which is harmful t...
