Embodiment 1

[0018] (1) In parts by weight, 35 parts of cyclohexanone, 5 parts of dispersant, 6 parts of polyvinyl chloride with a weight average molecular weight of 62,000, 12 parts of chloroform, 55 parts of acrylic resin, and 2 parts of wood with a particle diameter of 50 μm Powder, 5 parts of methyl cellulose and 5 parts of talcum powder with a particle size of 55 μm are mixed to prepare a thermal insulation coating;

[0019] (2) Heat the paper at an initial temperature of 20°C for 3 minutes at a heating rate of 2°C / min to perform the first preheating treatment; then raise the temperature at a heating rate of 7°C / min for 2 minutes to perform the second preheating treatment;

[0020] (3) Coat the waterproof paint on the preheated paper, heat at 110°C for 35 minutes, and emboss to make heat-insulating wallpaper A1.

Embodiment 2

[0022] (1) In parts by weight, 45 parts of cyclohexanone, 10 parts of dispersant, 15 parts of polyvinyl chloride with a weight average molecular weight of 90,000, 18 parts of chloroform, 65 parts of acrylic resin, and 5 parts of wood with a particle diameter of 80 μm Powder, 8 parts of hydroxypropyl methylcellulose and 5 parts of talcum powder with a particle size of 70 μm are mixed to prepare a thermal insulation coating;

[0023] (2) Raise the temperature of the paper at an initial temperature of 25°C for 5 minutes at a heating rate of 5°C / min to perform the first preheating treatment; then raise the temperature at a heating rate of 10°C / min for 5 minutes to perform the second preheating treatment;

[0024] (3) Apply the waterproof paint on the preheated paper, heat it at 130°C for 50 minutes, and emboss it to make heat-insulating wallpaper A2.

Embodiment 3

[0026] (1) In parts by weight, 40 parts of cyclohexanone, 7 parts of dispersant, 10 parts of polyvinyl chloride with a weight average molecular weight of 75,000, 15 parts of chloroform, 60 parts of acrylic resin, and 3 parts of wood with a particle diameter of 65 μm Powder, 7 parts of sodium carboxymethyl cellulose and 5 parts of talcum powder with a particle size of 55 μm are mixed to prepare a thermal insulation coating;

[0027] (2) Raise the temperature of the paper at an initial temperature of 23°C for 3 minutes at a heating rate of 3°C / min to perform the first preheating treatment; then raise the temperature at a heating rate of 8°C / min for 3 minutes to perform the second preheating treatment;

[0028] (3) Apply the waterproof paint on the preheated paper, heat it at 120°C for 40 minutes, and emboss it to make heat-insulating wallpaper A3.

Abstract

The invention discloses a preparation method of a heat insulation wallpaper. The method includes the steps that 1, cyclohexanone, a dispersing agent, polyvinyl chloride, chloroform, acrylic resin, wood powder, a thickening agent and talcum powder are mixed to prepare a heat insulation coating; 2, paper is subjected to preheating treatment; 3, the heat insulation coating is applied to the paper after preheating treatment, and heating and embossing are performed to prepare the heat insulation wallpaper, wherein the weight-average molecular weight of the polyvinyl chloride is 60,000-90,000, and the average particle size of the wood powder and the talcum powder is 50-80 microns. The heat insulation wallpaper prepared by adopting the method has the characteristics of abrasion resistance and can be used for a long time.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a thermal insulation wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is an interior decoration material used to paste walls, and is widely used in interior decoration of houses, offices, hotels, and hotels. The material is not limited to paper, but also includes other materials. Because of its various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, it is widely used in many other interior decoration materials. Wallpapers are divided into many categories, such as laminated wallpapers, coated wallpapers, embossed wallpapers, etc. Usually bleached chemical wood pulp is used to produce base paper, and then processed by different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. However, currently commercially availa...
