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:
The present invention relates to a kind of anti-flaming washable filter material and preparation technology thereof, 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 country 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 order benefit of environment and development is outstanding.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 air filting material take on the role who becomes more and more important 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 technical that atmospheric environment is administered, along with country's 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 used fire-retardant filtering material is because water-fast washing not, promptly needs after saturated more to renew when dust containing capacity reaches, and this had both increased the spending of enterprise, again environment had been caused pollution simultaneously.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:
The technical issues that need to address of the present invention are the preparation methods that disclose a kind of anti-flaming washable filter material, to satisfy the problem of contemporary society to the resource energy-conserving and environment-protective, the said anti-flaming washable filter material of the present invention is to form basic material by several different terylene or the acupuncture by a certain percentage of polypropylene chopped fiber peacekeeping three-dimensional crimp polyester staple, and then be soaked in acrylate polymer, in the fire retardant glue solution that the cyclic phosphate fire retardant is made into by a certain percentage, yet roll through two roll-ins again, oven dry, spray fire retardant glue solution again, oven dry is plated again, form fiber intersection points and fix and the filtering material of fiber surface, promptly obtain the present invention by smooth glue-line covering by glue point.
The preparation method of anti-flaming washable filter material of the present invention comprises the steps:
(1) preparation of needling material:
It is by terylene or polypropylene short fiber, and fibre fineness is 2-20dtex, and length is 50-80mm; Three-dimensional crimp polyester staple, fibre fineness are 5-18dtex, and length is 40-60mm; Above weight ratio is 85: 15, evenly mixes, and forms by shredding, combing, lapping, acupuncture, and needing machine speed is 1000-1500 time/minute, and bestock is 2000-4000 piece/meter, makes that several terylene or polypropylene fiber are well-proportioned to be connected as a single entity.
(2) preparation of fire retardant glue:
Acrylate polymer, cyclic phosphate fire retardant are evenly mixed weight ratio by weight the ratio of 40-60: 40-60.
(3) needling material is soaked in the mixture of (2) and water, with 0.5-10 rice/minute the speed operation, roll through two roll-ins, moisture content is removed, under 90 ℃-240 ℃ temperature, dry.
(4) again with the two-sided uniform sprinkling (2) of the material made in (3) and the mixture of water, under 90 ℃-200 ℃ temperature, dry, the press that enters 130 ℃-200 ℃ flattens, the rolling of cutting edge then, form fiber intersection points and fix and the filtering material of fiber surface, promptly obtain the present invention by smooth glue-line covering by glue point.
Because this filtering material is not only fire-retardant but also water-fast to be washed, so can be widely used in relevant use field both at home and abroad, reduced use cost, reduce the discharging of pollutant, thereby reached the effect of protection environment and energy-saving and emission-reduction.
