Problems solved by technology

[0003] However, the current painted wall coverings are 100% wood pulp paper, or composite wall coverings with non-woven fabrics, spunlace fabrics, or fabrics on the surface. Wood pulp paper is easy to be bumped and damaged during transportation, and especially on wallpaper The wall is easily torn and damaged during the glue application and pasting process, and the composite wall covering needs to be compounded with glue or other materials, which is difficult to meet the requirements of green environmental protection

Embodiment 1

[0044] A kind of production technology of high-strength environmental protection painting wall cloth, comprises the following steps,

[0045] S1: 38mm polyester staple fiber is carded into a web, pre-wetted, and then spunlaced through 4 drums, the spunlace pressure is 12MPa, and the bottom layer is obtained, and the weight of the bottom layer is 60g / m 2 ;

[0046] S2: The wood pulp is evenly dispersed in water to obtain a 3wt% pulp-water mixture, and then the pulp-water mixture is dehydrated on an inclined wire to form a fiber layer, and the fiber layer is impacted by 8 times of 4MPa flat wire spunlace to obtain the surface layer and the grammage of the surface layer 60g / m 2 ;;

[0047]S3: The bottom layer and the surface layer are butted together, and then reinforced by 9 flat-net spunlace methods. The pressure of the flat-net spunlace is 8MPa, and the mid-term wall covering is obtained;

[0048] S4: Pre-dry the mid-term wall covering. The pre-drying adopts hot air penetra...

Embodiment 2

[0050] The difference from Example 1 is that in step S4, the mid-term wall covering is pre-dried, and the mid-term wall covering is dried at a temperature of 90°C until the water content is 35wt%; the mid-term wall covering after pre-drying Embossing is carried out with embossing rollers; the mid-term wall covering after embossing is dried at a temperature of 80°C.

Embodiment 3

[0052] The difference from Example 1 is that in step S4, the mid-term wall covering is pre-dried, and the mid-term wall covering is dried at a temperature of 130°C until the water content is 20wt%; the mid-term wall covering after pre-drying Embossing is carried out with embossing rollers; the mid-term wall covering after embossing is dried at a temperature of 110°C.

Abstract

The invention relates to a production process of high-strength environment-friendly paint brushing wall cloth, which comprises the following steps: S1, carding polyester staple fibers into a net, conducting pre-wetting, and obtaining a bottom layer by a drum spunlace method; S2, uniformly dispersing wood pulp in water to obtain a pulp-water mixture, and performing wet-process net forming to obtaina surface layer; S3, enabling the bottom layer and the surface layer to abut against each other one by one and then conducting reinforcing through a flat screen spunlace method, so as to obtain medium-term wall cloth; and S4, carrying out after-treatment on the medium-term wall cloth. The effects of improving the environment-friendly performance of the painting wall cloth and achieving high composite strength are realized.

Description

technical field [0001] The application relates to the field of painted wall coverings, in particular to a production process of high-strength and environment-friendly painted wall coverings. Background technique [0002] Modern people pay more and more attention to a healthy and environmentally friendly lifestyle, especially in home decoration, requiring the use of green, environmentally friendly and healthy and harmless decorative materials. Wall decoration generally includes: wall covering, latex paint, diatom mud, wall tiles, etc. Due to people's pursuit of more personalized and fashionable wall decoration, more and more wall coverings are currently used, especially for painting. Wall cloth, after it is on the wall, you can use different colors of latex paint to paint according to your personal preferences, so that the wall can take into account the rich texture of the wallpaper and the bright and stable color of the paint. [0003] However, the current painted wall cove...
