Example Embodiment

[0013] 1. Preparation of flame-retardant bath

[0014] Flame retardant: water = (1-1.2): (10-12), the flame retardant is FR-101 polyester durable flame retardant produced by Qingdao Lianmei Chemical Co., Ltd., adjusted with disodium hydrogen phosphate or NaOH aqueous solution The pH value of the solution is 6.0-6.5;

[0015] 2. Use a two-dip and two-dip dipping machine for 2 minutes to ensure that the material is fully saturated so that the flame retardant is fully combined with the material, the bath temperature is 5-25 ℃, and the leaching rate is 60-70%;

[0016] 3. Use a tunnel oven to dry with hot air at 110-135°C for 12 minutes, and then heat-solidify at 185-205°C for 12 minutes;

[0017] 4. Input the dried and thermoset filter cotton into the cooling counter roller, and then cool and shape the roller after cooling. The temperature of the cooling counter roller is 50-60℃. After drying, the fluffy filter material is flattened and shaped, and the filter is guaranteed. Material ...

Abstract

The invention relates to flame-retardant filtration asbestos of DE type, which employs polyester, durable flame retardant to process DE type filtering material with steps of immersing, drying, thermosetting and cooling setting. With high flame retardant effect, good thermal stability, maintenance performance and resistance to acid and alkali; the invention which can keep the excellent flame retardant performance even after being washed contains no harmful elements such as formaldehyde, etc. and causes no pollution to environment.

Description

technical field [0001] The invention relates to an air filter and purification material, especially a filter material formed by heat-melting combination of polyester fiber and ES fiber (4080 double-membrane double-group low-melting point polyester fiber). Background technique [0002] The filter cotton material made of polyester fiber and ES fiber thermal fusion, referred to as DE filter cotton material, can be used in automobile painting production line, paint (room) production line, locomotive body production line and other occasions to filter air dust. In the prior art, in order to achieve the flame-retardant effect of the DE filter cotton material, it is processed by adding a certain amount of flame-retardant fiber to the material ratio of the DE-type filter material production process and spraying a flame-retardant agent on the surface. The process is relatively complicated. , the production cost is high, and the flame retardant effect is not ideal. Contents of the in...
