Problems solved by technology

[0003] PVC foam wallpaper mainly uses high-molecular polyvinyl chloride paste resin as the main raw material, adding plasticizers, foaming agents, flame retardants, viscosity reducers, fillers and other auxiliary materials for foam molding. PVC materials are not environmentally friendly. Use will age and produce harmful substances
Another type of coated wallpaper needs to be coated multiple times to achieve the embossed thickness. The process is cumbersome, which reduces the code rate of the finished product, consumes a lot of materials, and high manufacturing costs.

Embodiment 1

[0028] Foaming inkjet material, its raw material is: 25 parts of acrylic emulsions, 15 parts of polyurethane emulsions, 16 parts of polyvinyl alcohol glue (prepared by 12 parts of deionized water and 4 parts of PVA micelle), 5 parts of matte powder, 10 parts of 1 part sodium lauryl sulfate, 3 parts coconut oil fatty acid diethanolamide, 1 part aziridine, 25 parts deionized water.

[0029] Prepare as follows:

[0030] 1. Prepare polyvinyl alcohol glue: pre-weigh PVA colloids and deionized water, add deionized water to the mixing pot, turn on the mixer, slowly add PVA colloids, stirring speed 900r / min, after stirring for 20min, turn on the heating mode, Set the temperature to 80°C. When the temperature rises to 80°C, keep it warm for 1 hour, then change the interlayer water to cooling water, and when it cools to 50°C, filter it into a small bucket with a 300-mesh filter, seal it and let it stand for 24 hours before use;

Abstract

The invention belongs to the technical field of wall decoration materials and discloses a foaming inkjet material. The foaming inkjet material is prepared from 20-30 parts by weight of an acrylic emulsion, 10-20 parts by weight of a polyurethane emulsion, 10-20 parts by weight of polyvinyl alcohol glue, 3-8 parts by weight of matte powder, 5-12 parts by weight of sodium lauryl sulfate, 2-5 parts by weight of coconut fatty acid diethanolamide, 0.5-2 parts by weight of aziridine and 20-30 parts by weight of deionized water. The invention also discloses a preparation method of the foaming inkjetmaterial. The preparation method comprises: preparing polyvinyl alcohol glue, preparing base coating glue and preparing foaming inkjet glue. The foaming inkjet material has the advantages of environmental protection, wide application range, bright printing color and fast coating ink absorption speed.

Description

technical field [0001] The invention belongs to the technical field of wall surface decoration materials, in particular to a foaming inkjet material and a preparation method thereof. Background technique [0002] Wallpaper is also called wallpaper, which has the characteristics of rich colors, various patterns, safety and environmental protection, convenient construction, easy cleaning, surface water resistance, fire prevention and mildew resistance in interior decoration, and is widely used in residences, offices, hotels, coffee shops, specialty stores interior decoration. The wallpaper used in China is mainly PVC wallpaper, which is laminated with foamed or micro-foamed PVC layers on the surface and then embossed, which has a strong sense of concave and convex textures. The PVC layer is waterproof and can be washed directly with cloth, and the product price is cheap. Another kind of coated wallpaper, by repeatedly coating the ink-absorbing coating on the base material, af...
