Embodiment 1

[0027] The opaque environment-friendly non-woven wallpaper is made of the following raw materials in parts by weight:

[0028]

[0029] The preparation method comprises the following steps:

[0030] (1) Crushing, refining and pulping:

[0031] Put the proportioned amount of bleached softwood pulp and bleached hardwood pulp into the pulper at the same time for disintegration, and put them into the pre-grinding pool A after disintegration; put the proportioned amount of poplar chemical pulp into the pulper as well Disintegrate, after disintegrating, put it into the pre-grinding pool B;

[0032] The disintegrated bleached coniferous pulp and bleached hardwood pulp are ground for later use in a semi-free and semi-sticky manner; The ones are sent to the slurry mixing tank in proportion, then titanium dioxide is added, and white water is added to dilute to the required concentration for later use;

[0033] (2) Paper copying:

[0034] The prepared slurry is pumped to the headb...

Embodiment 2

[0037] The opaque environment-friendly non-woven wallpaper is made of the following raw materials in parts by weight:

[0038]

[0039]

[0040] The preparation method is the same as in Example 1.

[0041] After testing, the non-woven wallpaper obtained in this embodiment with a quantitative weight of 110 grams has an opacity of 90-92.

Embodiment 3

[0043] The opaque environment-friendly non-woven wallpaper is made of the following raw materials in parts by weight:

[0044]

[0045] The preparation method is the same as in Example 1.

[0046] After testing, the non-woven wallpaper obtained in this embodiment with a quantitative weight of 110 grams has an opacity of 88-90.

Abstract

The invention relates to non-transparent environment-friendly nonwoven wallpaper, which belongs to the technical field of nonwoven wallpaper. The non-transparent environment-friendly nonwoven wallpaper is prepared from the following raw materials in parts by weight: 35 to 45 parts of bleached needle leaf pulp, 40 to 50 parts of bleached broad leaf pulp, 10 to 20 parts of cottonwood pulp, and 3 to 9 parts of titanium dioxide. Due to the characteristic of high non-transparency, the nonwoven wallpaper not only solves the phenomenon that the bottom of a wall face is revealed when in decoration, but also help downstream customers to reduce the production cost, and promotes the application of wallpaper in the decoration industry; and for the fixed amount 110g (the lowest gram weight in the nonwoven wallpaper industry) of the nonwoven wallpaper, the non-transparency degree is 88 to 90 and is basically the same as that of 130g of nonwoven wallpaper, the non-transparency degree of 110g of ordinary nonwoven wallpaper is generally between 80 and 82, that is, 110g of nonwoven wallpaper can be used now to substitute the original 130g of nonwoven wallpaper needed by the customers, so that the production cost of the downstream customer is greatly saved.

Description

technical field [0001] The invention relates to an opaque and environment-friendly non-woven wallpaper, which belongs to the technical field of non-woven wallpaper. Background technique [0002] Non-woven wallpaper is the most popular new green and environmentally friendly wallpaper at present. Its preparation method is a kind of wallpaper obtained by wet molding with cotton, hemp, wood pulp and other natural plant fibers and polyester fibers as raw materials. The product does not contain any Polyvinyl chloride, polyethylene and chlorine elements, when completely burned, only carbon dioxide and water are produced, the visual effect and feel are soft, and the air permeability is good. The pattern of the surface wallpaper is richer, which is the perfect combination of noble and elegant classic pattern and simple and fashionable modern design style. Due to the above high-quality characteristics, non-woven wallpaper has developed rapidly in China in recent years. However, with ...
