Embodiment 1

[0037] The new process for preparing frosted PVC foamed wallpaper is realized in the following ways:

[0038] 1. Production process of coating section:

[0039] A. Preparation of paste: first put in plasticizer, epoxy soybean oil, potassium zinc stabilizer, one-half of the amount of viscosity reducer, put it in a mixer and stir at low speed for 5 minutes, and then continuously add AC foaming agent and PVC paste Resin, titanium dioxide, calcium carbonate. After the addition is complete, stir evenly, and finally add one-half of the viscosity reducer to adjust the viscosity to 3000 CPS, and filter.

[0040] The components of the paste are as follows, in parts by weight,

[0041] Plasticizer 60

[0042] Epoxidized soybean oil 12

[0043] AC blowing agent 5

[0044] Potassium zinc stabilizer 5

[0045] Viscosity Reducer 20

[0046] PVC paste resin 100

[0047] Titanium dioxide 15

[0048] Calcium carbonate 70.

[0049] The plasticizer is DOP (dioctyl phthalate); the AC foaming agent is azodicarbo...

Embodiment 2

[0067] The new process for preparing the imitation frosted PVC foamed wallpaper, the paste ratio in the coating section is as follows, and the others are the same as in Example 1.

[0068] The components of the paste are as follows, in parts by weight,

[0069] Plasticizer 65

[0070] Epoxidized soybean oil 11

[0071] AC blowing agent 5.5

[0072] Potassium zinc stabilizer 5

[0073] Viscosity Reducer 15

[0074] PVC paste resin 120

[0075] Titanium Dioxide 10

[0076] Calcium carbonate 80.

[0077] The plasticizer is DOP (dioctyl phthalate); the AC foaming agent is azodicarbonamide; and the viscosity reducing agent is a low-sulfur and low-aromatic hydrocarbon solvent.

Abstract

Belonging to the field of decorative materials, the invention discloses a preparation technology of a matte imitating foamed wallpaper. The technology adopts a microsphere foaming process, employs water-based microsphere foaming powder and a water-based acrylic emulsion as the binder to prepare an aqueous medium, which is printed on coated leather through gravure, then according to design need, conventional printing or printing of inhibiting foaming ink is carried out to endow the surface concavo-convex feeling, thus being closer to the need of wallpaper for rich layers. The technology improves the wallpaper quality, enriches wallpaper variety, and well meets consumers' demands.

Description

Technical field [0001] The invention relates to a process for preparing frosted foamed wallpaper, which belongs to the field of decorative materials. Background technique [0002] Wallpaper is the most popular soft decoration in decoration now, because its simplicity and convenience bring a more comfortable and natural living atmosphere to home life. There are many types of wallpapers, including wood fiber wallpaper, pure paper wallpaper, non-woven wallpaper, PVC wallpaper, etc. PVC wallpaper is waterproof and moisture-proof, and it is easy to construct. After the surface is contaminated, it can be wiped with a clean sponge or towel. It is durable and easy to maintain. This type of wallpaper is currently the most commonly used and most versatile wallpaper, which can be widely used in all homes and commercial places. Well received by consumers. However, traditional PVC wallpaper, after being foamed and softened, is generally pressed and cooled by embossing rollers. The products...
