Abstract
The invention discloses a preparation process of a flame-resistant washable filter material and belongs to the technical field of filter materials. The filter material is formed by mixing a polyester or polypropylene staple fiber and a three-dimensional crimped polyester staple fiber, wherein the fineness and the length of the polyester or polypropylene staple fiber are 3-25 dtex and 40-90 mm respectively; the fineness and the length of the three-dimensional crimped polyester staple fiber are 6-20 dtex and 30-55 mm respectively; such fibers are mixed by means of opening, carding, lapping and needle punching. The preparation method further comprises the following steps: drying the fiber mixture at 120-260 DEG C; allowing the dried fiber mixture to enter an ironing device of 150-200 DEG C for ironing; cutting the ironed fiber mixture into rings to form a finished product of the filter material, wherein the fiber cross points of the filter material are fixed by glue dots and the fiber surfaces of the filter material are coated with a layer of smooth glue. The filter material is good in filter effect, washable, long in service life, wide in application range, environmentally friendly, free of pollution, and low in production cost.
Description
Technical field:
The present invention relates to filtering material technical field, be specifically related to the preparation technology of anti-flaming washable filter material.
Background technology:
As everyone knows, a large amount of dust is contained (as dust in air, dust, flue dust, mine dust, sand dust, powder etc.) particle, because the very light in weight of these dust granules, so when the air effect flowed is in these dust granules, the weight of dust granule itself can be offset, these dust are made to be in a kind of floating state, only in the space of relative closure, air geo-stationary when, dust just can drop on the ground in gravitational effect, Here it is room that why door and window closes is in the situation of nobody residence, after a period of time, the dust that one deck is thick can be seen in furniture and ground.Dust in air content number with a lot of objective factor relevant, as weather condition, seasonal variations, industrial production, exploitation of mineral resources, desertification of land, soil erosion, environmental pollution etc.Dust on human body, on produce, on product quality, on environment, on natural scene attractive in appearance, have impact to the ecological balance.
Because to industrial negative effect, people expect that it is unfavorable to prevent, and result in three global large crises: shortage of resources, environmental pollution, ecological disruption not.Environmental pollution refers to natural or artificial destruction, adds certain material and exceed the self-purification capacity of environment and produce the behavior of harm in environment.(or due to artificial factor, environment is subject to the pollution of harmful substance, makes the normal life of biological growth and breeding and the mankind be subject to adverse effect.) because human factor makes the formation of environment or state change, Environmental Quality declines, thus upset and destroy the phenomenon of the normal working and living condition of the ecosystem and the mankind.
Air is one of the mankind's requisite environmental key-element of depending on for existence and development.But the increasing of population, mankind's activity is frequent, and natural cause impact makes atmosphere pollution serious, and environment protection is our instant obligation.The environment that the mankind depend on for existence is made up of natural environment and social environment.Natural environment is human lives and the summation of producing necessary natural conditions and natural resources, i.e. the summation of the natural cause such as stability of sunlight, temperature, weather, earth magnetism, air, water, rock, soil, animals and plants, microorganism and the earth's crust.And social environment be the mankind on the basis of natural environment, for improving constantly material and spiritual life level, by for a long time planned, on purpose develop, a kind of artificial environment progressively created and set up.Social environment is the mark of human material's civilization and spiritual civilization development, and it constantly changes along with economic and scientific and technical development.The quality of social environment, to the live and work of the mankind, has great impact to the progress of society.
Air environmental pollution is the emphasis of China's environment pollution control, the most important thing that air filting material has become relevant enterprise to develop, and current fire-retardant filtering material is not water-fastness, and service life is short, and after renewal, discarded filtering material is to environment.
Summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide the preparation technology of a kind of good filtration effect, cost of manufacture is low, environmental pollution is little anti-flaming washable filter material.
The preparation technology of anti-flaming washable filter material of the present invention, it comprises following steps:
1, the preparation of filtering material:
It is mixed by terylene or polypropylene short fiber, three-dimensional crimp polyester staple, and wherein the fibre fineness of terylene or polypropylene short fiber is 3-25dtex, and length is 40-90mm; The fibre fineness of three-dimensional crimp polyester staple is 6-20dtex, and length is 30-55mm; During mixing, completed by shredding, combing, lapping, this several method of acupuncture.
2, the preparation of fire retardant glue:
Acrylate polymer, cyclic phosphate fire retardant, sodium dihydrogen phosphate are mixed according to the ratio uniform of 30-55:40-60:4-10.
3, filtering material is immersed in the fire retardant glue of step 2 and the mixture of water, runs with the speed of 2-8 m/min, roll through two roll-in, by removing moisture, dry at the temperature of 100-200 degree Celsius.
4, the material two-side made in step 3 is evenly sprayed the mixture of fire retardant glue and water, dry to enter in the flat equipment of lying of 150-200 degree Celsius at the temperature of 120-260 degree Celsius and plate, be cut into circle, form fiber intersection points and fixed the filtration finished-product material covered by smooth glue-line with fiber surface by glue point.
As preferably, the speed of acupuncture in described step 1 is 1500-2200 beat/min, and bestock is 2500-4500 piece/meter.
As preferably, the bake out temperature in described step 3 is lower than the bake out temperature in step 4.
As preferably, the sodium dihydrogen phosphate in described step 2 replaces with according to poly terephthalic acid.
As preferably, the acrylate polymer in described step 2 replaces with aqueous polyurethane, melmac mixture.
Beneficial effect of the present invention: its good filtration effect, water-fastness, long service life, applicable scope is wide, environment friendly and pollution-free, and cost of manufacture is low.
