Embodiment 1

[0090] The components in the coating material were measured in parts by weight and mixed at room temperature to obtain coating sample 1#. Among them, the coating material includes water-based sol and pigment, and the water-based sol includes the following components in parts by weight: 20 parts of water-based emulsion, 22 parts of water-based adhesive, 6 parts of kaolin, 30 parts of calcium carbonate, 8 parts of talc, titanium dioxide 12 parts, 8 parts of barium sulfate, the water-based emulsion is water-based acrylic acid, and the water-based adhesive is starch dextrin. The pigment is a mixed pigment of phthalocyanine blue and phthalocyanine green, and the addition amount of the pigment is 0.2wt% of the amount of the aqueous sol.

[0091] Take the non-woven fabric as the base layer sample 1#, and the weight ratio of the base layer to the coating is 1:1.2.

[0092] The coating sample 1# was evenly coated on the base layer sample 1# by a coater at a speed of 30 m / min, put into...

[0094] The components in the coating material were measured in parts by weight and then mixed at room temperature to obtain coating sample 2#. Among them, the coating material includes water-based sol and pigment, and the water-based sol includes the following components in parts by weight: 25 parts of water-based emulsion, 18 parts of water-based adhesive, 8 parts of kaolin, 25 parts of calcium carbonate, 8 parts of talc, titanium dioxide 15 parts, 6 parts of barium sulfate, the water-based emulsion is water-based polyurethane, and the water-based adhesive is polyvinyl alcohol. The pigment is bright red pigment, and the amount of the pigment added is 0.3wt% of the amount of the water-based sol. Take the cross cloth as the base layer sample 2#, and the weight ratio of the base layer to the coating is 1:1.25.

[0095] The coating sample 2# was uniformly coated on the base layer sample 2# by a coating machine at a speed of 20 m / min, put into an oven, and dried at 130° C. for 2 m...

Embodiment 3

[0097] The components in the coating material were measured in parts by weight and mixed at room temperature to obtain coating sample 3#. Among them, the coating material includes water-based sol and pigment, and the water-based sol includes the following components in parts by weight: 15 parts of water-based emulsion, 28 parts of water-based adhesive, 10 parts of kaolin, 20 parts of calcium carbonate, 8 parts of talc, titanium dioxide 16 parts, 8 parts of barium sulfate, the water-based emulsion is water-based acrylic acid, and the water-based adhesive is polyethylene vinyl acetate copolymer. The pigment is a medium yellow pigment, and the addition amount of the pigment is 0.15wt% of the amount of the aqueous sol.

[0098] Take non-woven paper as base layer sample 3#, and the weight ratio of base layer to coating is 1:1.3.

Abstract

The invention provides a seamless wall covering material without PVC base material, which includes a coating material, including water-based sol and pigments, and the water-based sol includes the following components in parts by weight: water-based emulsion 10~ 40 parts; 10-50 parts of water-based adhesive; 5-20 parts of kaolin; 10-50 parts of calcium carbonate; 20 parts of talcum powder; 5-30 parts of titanium dioxide; . The invention further provides a seamless wall cloth without PVC cloth base material and a preparation method thereof. The invention provides a seamless wall cloth without PVC cloth base material, which combines the advantages of wall cloth and latex paint and other similar products, and is green, environmentally friendly, seamless, odor-free, non-flammable, sound-proof, and heat-insulating , Waterproof, anti-mildew, anti-bacteria and other beneficial effects, it is very worthy of popularization and application in practice.

Description

technical field [0001] The invention belongs to the technical field of building decoration and decoration materials, and relates to a seamless wall covering that does not contain a PVC cloth base material. Background technique [0002] Among the raw materials for wall surface treatment, there are wallpaper, wall covering, stone, ceramic tile and latex paint, etc., each with its own characteristics and advantages and disadvantages. The disadvantages are explained one by one below. [0003] There are two types of wallpapers: PVC and non-woven paper. Due to the poor air permeability of PVC wallpaper, the wet environment will cause great damage to the wall surface, and it is easy to bulge air bubbles; although PVC plastic itself is non-toxic, the VCM used for polymerizing PVC has carcinogenic effects and brings hidden dangers to healthy life; Textile paper is easy to burn, warped, moldy, not resistant to dirt, and has a short service life. It is easy to cause damage during cons...
