Embodiment 1

[0029] A kind of preparation technology based on waste paper production wallpaper of the present embodiment is characterized in that, comprises the following steps:

[0030] Step 1, hot rolling 100 parts of pretreated waste paper and polystyrene particles according to the weight ratio of 5:1 to obtain pre-wallpaper, and then send it to a calender for calendering to obtain a wallpaper matrix;

[0031] Step 2: Soak the wallpaper substrate in step 1 in the strengthening solution for 1-2 hours at a temperature of 60°C, then take it out, drain it, and dry it until the surface moisture content is 3%;

[0032] Step 3: The wallpaper treated in step 3 is first subjected to sandblasting and roughening treatment. The sandblasting roughening treatment uses a sandblasting machine with an air pressure of 0.2MPa and a sandblasting distance of 3cm, and then uses arc spraying on the surface of the wallpaper with a thickness of 0.1mm coating, and then air-dried;

[0033] The coating comprises ...

Embodiment 2

[0044]A kind of preparation technology based on waste paper production wallpaper of the present embodiment is characterized in that, comprises the following steps:

[0045] Step 1, hot rolling 200 parts of pretreated waste paper and polystyrene particles according to the weight ratio of 5:1 to obtain pre-wallpaper, and then send it to a calender for calendering to obtain a wallpaper matrix;

[0046] Step 2: Soak the wallpaper substrate in step 1 in the strengthening solution for 2 hours at a temperature of 70°C, then take it out, drain it, and dry it until the surface moisture content is 6%;

[0047] Step 3: The wallpaper treated in step 3 is first subjected to sandblasting roughening treatment. The sandblasting roughening treatment uses a sandblasting machine with an air pressure of 0.4MPa and a sandblasting distance of 5cm, and then uses arc spraying on the surface of the wallpaper with a thickness of 0.4mm coating, and then air-dried;

[0048] The coating comprises the fol...

Embodiment 3

[0060] A kind of preparation technology based on waste paper production wallpaper of the present embodiment is characterized in that, comprises the following steps:

[0061] Step 1, hot rolling 150 parts of pretreated waste paper and polystyrene particles according to the weight ratio of 5:1 to obtain pre-wallpaper, and then send it to a calender for calendering to obtain a wallpaper matrix;

[0062] Step 2: Soak the wallpaper substrate in Step 1 in the strengthening solution for 1.5 hours at a temperature of 65°C, then take it out, drain it, and dry it until the surface moisture content is 4.5%;

[0063] Step 3: The wallpaper treated in step 3 is subjected to sandblasting roughening treatment first, using a sandblasting machine with an air pressure of 0.3MPa and a sandblasting distance of 4cm for treatment, and then using arc spraying on the surface of the wallpaper with a thickness of 0.25mm coating, and then air-dried;

[0064] The coating comprises the following raw mater...

Abstract

The invention discloses a preparation process for producing wallpaper based on waste paper, which comprises the following steps: firstly carrying out hot rolling on 100-200 parts by weight of pretreated waste paper and polystyrene particles according to a weight ratio of 5:1 to obtain pre-fabricated wallpaper, and then carrying out calendaring forming operation in a calendaring machine to obtain awallpaper base. The waste paper contains cellulose, hemicellulose and lignin, wherein the cellulose is the most in content, so that when the waste paper is treated, the waste paper is firstly converted into waste paper pulp, a large number of cellulose bases are exposed; the cellulose bases contain a large number of hydroxyl groups, so that molecular chains of the cellulose bases can directly form hydrogen bonds, the activity of the cellulose bases is influenced, and a stable state is achieved.

Description

technical field [0001] The invention relates to the technical field of waste paper production, in particular to a preparation process for producing wallpaper based on waste paper. Background technique [0002] Wallpaper, also known as wallpaper, is an interior decoration material used to paste walls, and is widely used in interior decoration of houses, offices, hotels, hotels, etc. The material is not limited to paper, but also includes other 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. It has certain strength, toughness, beautiful appearance and good water resistance. [0003] Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualifi...
