Problems solved by technology

[0003] However, in the existing bamboo fiber filter materials, it is difficult to solve the problem of its weak flame retardancy. When the ambient temperature is too high to ignite, it cannot actively extinguish the flame, which leads to its relatively limited application range and low safety factor. Low; and the tensile strength or tear strength of existing bamboo fiber filter material is difficult to guarantee, and the influence of formaldehyde is accompanied, and then greatly shortens its normal service life; Simultaneously in the production process of existing bamboo fiber filter material , the absorption effect between raw materials and additives is poor, which in turn affects product quality

Embodiment 1

[0035] A bamboo fiber filter material, comprising an inner layer material and an outer layer material, the outer layer material is arranged on both sides of the inner layer material, the outer layer material is modified cotton cloth, and the thickness is controlled at 1 mm;

[0036] The modified cotton and linen cloth is produced by the following steps: first scrape and grind the two sides of the cotton and linen cloth until lint appears on the surface, then use a sweater needle with a diameter of 1.5 mm to evenly pierce the pinholes, and rub and comb Finally, put it in polyurethane jelly glue for 60 minutes, and pour expandable graphite particles into it to blend with it, and control the infiltration temperature at 70 degrees, then scrape and grind it to an overall thickness of 2.5 mm, and then use it with a diameter of 0.15mm stainless steel needles are used to evenly pierce the pinholes, and finally cooled and shaped, edged and trimmed to obtain modified cotton linen;

Embodiment 2

[0046] A bamboo fiber filter material, the difference from Example 1 is that the outer layer material is cotton cloth.

[0047] A kind of preparation technology of bamboo fiber filter material, the difference with embodiment 1 is, without step 1) and outer layer material is cotton linen.

Embodiment 3

[0049] A bamboo fiber filter material, the difference from Example 1 is that expandable graphite particles are not added during the treatment of the modified cotton cloth.

[0050] A kind of preparation technology of bamboo fiber filter material, the difference with embodiment 1 is that no expandable graphite particle is added in the described step 1).

Abstract

The invention discloses a bamboo fiber filtration material and a preparation process thereof. The bamboo fiber filtration material comprises an inner layer material and outer layer materials, the outer layer materials are arranged on the two sides of the inner layer material, the outer layer materials are modified diablement fort, and the thickness of the outer layer materials is controlled to be1 mm. The modified diablement fort is produced through the following steps that the two side faces of diablement fort are subjected to scraped finish firstly until cotton velvet is generated on the surface of the diablement fort, then needle holes are evenly formed in a pricked mode by a knitting needle with the diameter being 1.5 mm, after kneading and combing, the diablement fort is placed in polyurethane jelly glue to be soaked for 60 minutes, expandable graphite particles are poured into the polyurethane jelly glue and blended with the polyurethane jelly glue, the soaking temperature is controlled to be 70 DEG C, then the diablement fort is subjected to scraped finish until the overall thickness is 2.5 mm, then needle holes are evenly formed in a pricked mode by a stainless steel needle with the diameter being 0.15 mm, finally cooling forming, edge grinding and trimming are conducted, and thus the modified diablement fort is obtained. According to the bamboo fiber filtration material, the flame retardant effect and the durability of the bamboo fiber filtration material can be further improved while the influence of formaldehyde is reduced.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a bamboo fiber filter material and a preparation process thereof. Background technique [0002] Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo, and it is also the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air permeability, instant water absorption, wear resistance and dyeability, etc. It is often used in clothing fabrics, mats, bed sheets, curtains and scarves, and has also been widely used as a filter material for gases and liquids. application. [0003] However, in the existing bamboo fiber filter materials, it is difficult to solve the problem of its weak flame retardancy. When the ambient temperature is too high to ignite, it cannot actively extinguish the flame, which leads to its relatively limited application range and low safety factor. Low; and the tensile strength or ...
