Abstract
The invention relates to a method for preparing a regenerated cotton filtration material with antiflaming property and water resistance. The preparation process of the invention comprises the following steps: step (1) air-laid material preparation: the filtration material is prepared by carrying out opening, mixing and air laying on the regenerated cotton short fibers and polyester short fibers, and various regenerated cottons and polyester short fibers are evenly laid into a whole; step (2) antiflaming glue preparation: the antiflaming flue is prepared according to the weight ratio that melamine resin or polyvinyl acetate compound or acrylic ester polymer to cyclophosphate or organic phosphate or nitrogen organic phosphate flame retardant is 40-70:30-60; and step (3) the mixture of the antiflaming glue and water prepared in step (2) is evenly sprayed on the double surfaces of the air-laid material prepared in the step (1), and the filtration material is obtained after the processes of drying and ironing by an ironing machine. The filtration material of the invention not only can resist flaming, also can resist washing, is easy to degrade, lower use cost, and reduce emission of the pollutant, thus achieving the effects of environmental protection and energy saving and emission reduction.
Description
Technical field:
The present invention relates to a kind of filtering material and preparation method thereof, particularly a kind of preparation method of regenerated cotton filtration material with antiflaming property and water resistance.
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 homemade fire-retardant filtering material is not owing to water-fastly wash and be difficult for degraded, promptly needs more to renew when dust containing capacity reaches capacity after, and this had both increased the spending of enterprise, and the while has been caused pollution to environment again.And the regenerated cotton filtration material with antiflaming property and water resistance of my company development removes water to rinse well and can reuse after dust containing capacity reaches capacity, and this greatly reduces the cost of enterprise, reaches refuse reclamation simultaneously and has reduced pollution to environment again.
Summary of the invention:
The technical problem that the present invention solves is the preparation method who discloses a kind of regenerated cotton filtration material with antiflaming property and water resistance.
The preparation method of a kind of regenerated cotton filtration material with antiflaming property and water resistance of the present invention, it is characterized in that: it is by several regeneration cotton short fibers and polyester staple fiber, and shredding by a certain percentage mixes, air lay forms base material, is sprayed on to dry after the fire retardant glue of proportioning by a certain percentage to form again; Preparation technology of the present invention is: step (1), the preparation of airlaid material: filtering material, it is to be 0.5-16dtex by fibre fineness, length is that regeneration cotton short fiber, the fineness of 10-25mm is 10-20dtex, length is that the polyester staple fiber of 51-80mm is by shredding, mix, air lay forms, the air lay motor speed be 1-10 rice/minute, making the well-proportioned shop of several regeneration cottons and polyster fibre is one, the regeneration cotton short fiber: polyester staple fiber=85: 15 weight ratios, thickness are 1-7mm; Step (2), the preparation of fire retardant glue: with melmac or polyvinyl acetate compound or acrylate polymer: the weight ratio of cyclic phosphate or phosphate or nitrogen phosphate flame retardant :=40-70: 30-60 is carried out proportioning; Step (3), with the prepared fire retardant glue that goes out of the two-sided uniform sprinkling step (2) of the airlaid material made in the step (1) 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 finish preparation of the present invention by smooth glue-line covering by glue point.
Not only fire-retardant but also water-fast the washing and easily degraded of filtering material that the present invention is prepared so can be widely used in relevant use field both at home and abroad, reduced use cost, reduced the discharging of pollutant, thereby reached the effect of protection environment and energy-saving and emission-reduction.
