Embodiment 1

[0013] (1) Preparation of acupuncture composite materials:

[0014] It is composed of polypropylene or polyester staple fibers with a fiber fineness of 3dtex and a length of 51mm and a fiber grid base cloth with a specification of 2×2mm. Among them, polypropylene or polyester staple fibers: grid base fabric=90: 10. Weight ratio, through opening, carding, laying, and needle punching to form the lower base material, then laying grid base cloth in the middle, and finally laying polypropylene or polyester fiber mesh on the upper layer, and combining the three with needle punching, needle punching machine The speed is 1200 times / min, and the needle planting density is 2600 pieces / m, so that the polypropylene or polyester staple fiber and the grid base cloth are evenly connected as a whole, and the thickness is 2mm.

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...
