Problems solved by technology

[0002] With the rapid development of the economy, the environmental pollution is becoming more and more serious. Among them, industrial waste gas and automobile exhaust gas seriously affect people's healthy life. Automobile air-conditioning filters can filter the air entering the compartment from the outside to improve the cleanliness of the air. At present , the filter material for automotive air conditioners can only filter and absorb leaves, tiny particles, pollen and dust, etc., and has no bactericidal effect, and dirt such as dust will accumulate on the filter material for a long time and will also breed bacteria. These dust and bacteria enter from the air outlet In the car, it will also pose a threat to the health of the people in the car. In addition, in recent years, the phenomenon of PM2.5 and smog has become serious, and the requirements for the dust collection efficiency, adsorption capacity, and dust holding rate of filter materials are higher.

Embodiment 1

[0017] The air-conditioning filter material includes a non-woven layer and a graphene network layer, and the non-woven layer contains 30% bamboo fiber, 60% polyester fiber, and 10% skin-core composite fiber. Wherein, the polyester fiber is polyethylene terephthalate fiber; the skin-core composite fiber is an eccentric skin-core composite fiber, which uses polyether ester elastomer as the core layer and polyester as the skin layer.

[0018] The preparation method of filter material for air-conditioning, the steps are as follows,

[0019] 1) Preparation of non-woven fabric layer: Bamboo fiber, polyester fiber, sheath-core composite fiber are mixed and opened, sent to the cotton feeding box, carded, laid, and then passed through hot air at a temperature of 190°C at a speed of 12m / min The box is thermally bonded, and the thickness is adjusted by rollers to obtain a non-woven layer;

Abstract

The invention discloses a filtering material for an air conditioner and a preparation method thereof, and relates to the technical field of a filtering material. The filtering material is prepared from a nonwoven fabric layer and a graphene network layer, wherein the nonwoven fabric layer contains 30-50% of bamboo fiber, 40-60% of polyester fiber and 10-30% of sheath-core composite fiber. The preparation method comprises the following steps: impregnating the nonwoven fabric layer in a graphene propylene glycol solution; drying to obtain the filtering material. The filtering material prepared by the invention has perfect bacteria inhibiting and killing ability and great absorbability, and can absorb tiny particles in air, filter air pollutants such as pollen, haze and PM2.5 and inhibit the growth and reproduction of bacteria; moreover, the filtering material also has excellent air permeability, smooth air circulation inside and outside a car is ensured, and the air quality in the car is improved.
