Preparation method of multi-component flame retardant easy-to-clean filtering material and non-woven filtering material

Abstract

The invention discloses a preparation method of a multi-component flame retardant easy-to-clean filtering material and a non-woven filtering material, and relates to a preparation method of a filtering material. The preparation method of the multi-component flame retardant easy-to-clean filtering material comprises the steps of unpacking and checking 30-40% of melting point polyester staple fiber, 20-30% of flame retardant polyester staple fiber in 20-30% of three types of fibers and 8-15% of aramid staple fiber according to percentage by mass for evenly mixing, then loosening and carding, lapping after carding, adding lapped raw materials into a hot melt forming area, enabling low-melting-point polyester staple fiber of the filtering material to melt firstly at high temperature of 190-215 DEG C and be subjected to hot melting and bonding with evenly-lapped high-melting-point polyester staple fiber and the aramid staple fiber to form a whole body which is a finished product. The preparation method is simple; the product is environmentally friendly and safe; the strength of the filtering material after spray finishing is improved; the hand feel of the filtering material is stiff, thus facilitating pleating; the effective filtering area is increased; and the filtering material is stable and durable in flame retardant performance and good in decontamination effect.

Description

[0001] Technical field: [0002] The invention relates to a method for preparing a filter material, in particular to a method for preparing a multi-component flame-retardant and easy-to-decontaminate filter material and a non-woven filter material. Background technique: [0003] With the continuous development of science and technology and modern industry, people pay more and more attention to the air quality of outdoor environment and indoor air quality, the continuous development and improvement of dust removal and purification technology and the expansion of application range, no matter in quantity or variety and New requirements have been put forward in terms of quality. [0004] The development and application of non-woven filter materials has many advantages, because it has a certain thickness, the fibers are intricately formed into a network structure, the pores are many and the path is tortuous, the filter area is increased, the airflow resistance is small, and the f...

Problems solved by technology

However, the non-woven air filter materials currently used have relatively few functions, unstable flame retardancy, and are not resistant to washing. Especially in summer, when the temperature rises, the air filter material is saturated with dust, easy to pollute, and consumes a lot. Cause the filter to block and stop, affecting the normal operation of the air conditioning filter system
