Abstract
A preparation method of a flame-retardant and washable filter material comprises the following steps: step (1) a pet staple fiber, a three-dimensional crimp pet staple fiber and a low melting point fiber are evenly mixed together according to the weight ratio of 50:15:35 and shaped after being loosened, carded, mesh placed and hot melted; and the temperature of a hot melt machine is from 180 to 240 DEG C which causes the fibers to be hot melted into a uniform body evenly so as to make the basic material of 3 to 30 mm; step (2) the preparation of the flame retardant gel: the gel is formed by evenly mixing a melamine resin, an acyclic phosphate flame retardant and a poly butylene terephthalate diester according to a weight ratio; step (3) step (1) is emerged into a mixed solution mixed by step (2) with water, deprived of water after being compacted by a twin-roll and dried at the temperature of 90 to 240 DEG C; and step (4) two sides of the material formed in step (3) are evenly sprayed with the mixed solution mixed by the flame-retardant gel with water in step (2), dried at the temperature of 90 to 200 DEG C, compacted by an iron machine at the temperature of 130 to 200 DEG C and then trimmed to rolls. The filter material is flame-retardant and washable.
Description
Technical field:
The present invention relates to a kind of preparation method of anti-flaming washable filter material, relate to the filtering material of systems such as a kind of concentrated ventilation, central air-conditioning and fluid purification specifically.
Background technology:
China is the maximum developing china of world population, since phase late 1970s, along with China's economic development continuously and healthily, the environmental problem that occurs stage by stage in the century-old course of industrialization in the developed country is concentrated in China and is occurred, and the contradiction of environment and development becomes increasingly conspicuous.The resource relative shortage, ecological environment frailty, the environmental carrying capacity deficiency becomes the significant problem in the Chinese development gradually.The Eleventh Five-Year Plan of China is had higher requirement to environmental protection, and aspects such as water, gas, sound, slag all arrive filtering material, filtering material industry market promise well with more applications.Along with the pay attention to day by day of people to atmospheric environment and IAQ, the issuing and implementation of a series of environmental regulations make the role who becomes more and more important that air filting material is being taken in environmental improvement, and have obtained significant progress.Air filting material has occupied the 3rd in six big markets of international filtering material, become fastest-rising part in the international filtering material market.Air environmental pollution is the emphasis of China's environmental pollution control, air filting material is the important means that atmospheric environment is administered, along with the world perfect day by day to the increasing of environmental protection investment and environmental regulation, the application prospect of air filting material in atmospheric environment is administered will be more wide.At present, our employed fire-retardant filtering material is because water-fast washing not, promptly needs more to renew when dust containing capacity reaches capacity after, and this has promptly increased the spending of enterprise, and the while has been caused pollution to environment again.And the anti-flaming washable filter material of my company's development removes water to rinse well and can reuse after dust containing capacity reaches capacity, and this greatly reduces the cost of enterprise, has reduced the pollution to environment simultaneously again.
Summary of the invention:
Task of the present invention is to propose a kind of fire-retardant, water-fast preparation method who washes, economizes on resources filtering material, task of the present invention is finished like this: it comprises polyester staple fiber, three-dimensional crimp polyester staple, low-melting fiber and fire retardant glue, it is characterized in that: step 1: it is by polyester staple fiber, fibre fineness is 6-35dtex, and length is 50-80mm; Three-dimensional crimp polyester staple, fibre fineness are 6-25dtex, and length is 51-70mm; Low-melting fiber, fibre fineness is 2-10dtex, length is 40-70mm, above weight ratio is 50:15:35, evenly mixes, by shredding, combing, lapping, hot melt molding, 180-240 ℃ of fuse machine temperature, 1-6 meters/minutes of the speeds of service make the well-proportioned hot melt molding of several fibers be-body, make the base material of 3-30mm.Step 2: the preparation of fire retardant glue: the ratio by weight 40-60:35-60:2-6 of melmac, phosphate flame retardant, poly terephthalic acid diester is evenly mixed.Step 3: step 1 is soaked in the mixed solution of step 2 and water,, rolls, moisture content is removed, under 90 ℃-240 ℃ temperature, dry through two roll-ins with 0.5-6 meters/minutes speed operation.Step 4: with the fire retardant glue of the two-sided uniform sprinkling step 2 of the material made in the step 3 and the mixed solution of water, dry under 90 ℃-200 ℃ temperature, the press that enters 130 ℃-200 ℃ flattens the rolling of cutting edge then.Anti-flaming washable filter material has fiber intersection points and is covered by smooth glue-line with fiber surface by glue point is fixing.The present invention has following effect: this material is not only fire-retardant but also water-fast to be washed, and water cleans more than 9 times, and its flame retardant effect still can reach more than the E level, the initial resistance of this filtering material :≤20-80pa, dust containing capacity: 〉=50-400g/m
