Problems solved by technology

[0005] The technical problem to be solved in the present invention is to disclose a preparation method of a flame-retardant and washable filter material, so as to meet the problems of resource conservation and environmental protection in contemporary society. The flame-retardant and washable filter material in the present invention is made of several different polyester Or polypropylene staple fiber and three-dimensional crimped polyester staple fiber are needled in a certain proportion to form the basic material, and then soaked in a flame-retardant glue solution made of acrylic ester polymer and cyclophosphate flame retardant in a certain proportion. Double-roll rolling, drying, spraying flame-retardant glue solution, drying and ironing to form a filter material with fiber intersections fixed by glue spots and fiber surface covered by a smooth glue layer, that is, the present invention is obtained.

Abstract

The invention provides a process for preparing a flame-retarding washable filtering material. The flame-retarding washable filtering material is prepared by the following steps of: needling various terylene or polypropylene staple fiber and three-dimensional crimp polyester staple fiber by a certain proportion to prepare a basic material; subsequently soaking the basic material in a flame-retarding adhesive solution prepared by mixing an acrylate polymer and a cyclic phosphate flame retardant with a certain proportion; subsequently rolling by dual rollers, drying and spraying the flame-retarding adhesive; and subsequently drying and ironing out the solution, thus forming the filtering material with the fiber crossing fixed by adhesive point and fiber surface covered by a smooth adhesive layer. The process is flame-retarding and washable.

Description

Technical field: [0001] The invention relates to a flame-retardant and water-washable filter material and a preparation process thereof, in particular to a filter material for systems such as centralized ventilation, central air conditioning, and liquid purification. Background technique: [0002] China is the most populous developing country in the world. Since the end of the 1970s, with the continuous and rapid development of China's economy, the environmental problems that have emerged in stages in the industrialization process of developed countries for hundreds of years have concentrated in China. The contradiction between environment and development Eyes are prominent. The relative shortage of resources, fragile ecological environment, and insufficient environmental capacity have gradually become major problems in China's development. [0003] my country's "Eleventh Five-Year Plan" puts forward higher requirements for environmental protection. Water, gas, sound, slag ...
