Problems solved by technology

[0004] The technical problem to be solved in the present invention is to disclose a preparation process 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 polypropylene staple fiber and fiber The grid base cloth is needle-punched and composited into a basic material, and then soaked in a flame-retardant glue solution made of melamine resin, cyclophosphate flame retardant, and polyethylene terephthalate in a certain proportion, and then passed through a double-roller Rolling, drying, spraying flame-retardant glue solution on the surface, drying, and ironing to form a filter material with fiber intersections fixed by glue points and fiber surface covered by a smooth glue layer. The flame-retardant and washable filter material of the present invention The preparation process comprises the following steps:

Abstract

The invention discloses a flame-retardant and washable filter material and a preparation technology thereof. The flame-retardant and washable filter material is the filter material which is prepared by the following steps: a basic material is acupunctured and compounded by a polypropylene staple fiber and a fiber mesh base cloth, then emerged into a flame-retardant solution which is prepared by melamine resin, an acyclic phosphate flame retardant and poly butylene terephthalate diester according to a certain proportion and then compacted by a twin-roll and dried and ironed out after the surface is sprayed with the flame-retardant solution; and the formed fiber crossing points are fixed by gel points with the filter material with the fiber surface being covered by a smooth glue layer. The filter material is flame-retardant 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 filter materials for various engine air filter and liquid purification systems. 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. my country's "Eleventh Five-Year Plan" puts forward higher requirements for environmental protection. Water, gas, sound, slag and other aspects will be more applied to f...
