Embodiment 1

[0021] Amount of raw materials: 70% aeolian sand, 1% coupling agent, 3.5% lubricant, 0.5% stabilizer, 25% polyethylene.

[0022] Preparation of wallpaper: After dispersing and mixing the aeolian sand and coupling agent, put it into a grinder and grind it for about 1 hour, sort and sieve, take 600-800 mesh powder, add lubricant and stabilizer, mix it and put it into high-speed mixing After mixing by machine for 20 minutes, add polyethylene and stir and mix for 5 minutes, put it into the internal mixer for 20 minutes, extrude and pelletize, put the pellets into the flow calender to shape, and then emboss and print to make a web Wallpaper with a width of 1.2m.

Embodiment 2—4

[0024] Create a wallpaper extruded from three layers. Among them, both the upper and lower layers use material A, and the middle layer uses material B. The raw material ratio of material A and material B is listed in the table below. The production method is to mix material A and material B with aeolian sand and coupling agent, grind, sieve, then mix with other raw materials, banbury, extrude and granulate, and then put them into a three-laminar flow calender Forming in the middle to make a three-layer structure wallpaper.

Abstract

The invention discloses the application of aeolian sand to the preparation of synthetic paper. The method of using the aeolian sand to prepare the synthetic paper comprises the following steps: adding a coupling agent into the aeolian sand, dispersing, mixing, grinding the aeolian sand, screening aeolian sand powder, adding a lubricant, a stabilizer and polyolefin resin, mixing, extruding, granulating, carrying out casting molding and calendaring molding, embossing and printing to obtain the wall paper or wrapping paper.

Description

technical field [0001] The invention relates to a production material and a preparation method of wallpaper. The so-called wallpaper is a covering used for interior wall decoration of houses. [0002] Background technique [0003] The present age has developed the technology of making paper substitutes including wallpapers and wrapping papers by using polymer materials as base materials and filling them with powdered minerals. This paper substitute is called synthetic paper. At present, the material used as synthetic paper filler is stone powder which is crushed and ground into stone such as marble. This crushing, grinding and sieving process is time-consuming and laborious, and consumes a lot of energy. It is the development direction of this industry to look for the natural sand that exists in nature to make synthetic paper filler. [0004] Aeolian sand is a kind of natural sand with tiny particles. It is an accumulation formed on the surface of the ground through na...
