Plate type solar heat insulation polyester cotton and processing technology thereof

Abstract

The invention discloses plate type solar heat insulation polyester cotton and a processing technology thereof. The processing technology comprises the following steps of: hotly shaping a heat insulation padded cotton quilt and a strong force padded cotton quilt in a first section oven to obtain a heat insulation cotton quilt layer and a strong force cotton quilt layer which have different grades and different hardness respectively; and spreading a layer of hot melt fiber net bonder to the strong force cotton quilt layer, and compounding with an radiation-proof aluminum foil to form a four-layer compound structure. The invention has performances of special requirements of high efficiency, heat storage, heat preservation, flame resistance and heat insulation, and raw material can be recycled by 100% due to no chemical reaction in the whole process. The toxicity and irritation will not be caused in the whole production process and the product, so that the human health is ensured and the environment is protected. The melting point is not less than 190 degrees centigrade and heat conducting coefficient is not more than 0.035W / m.k through detection, so the plate type solar heat insulation polyester cotton is suitable for use as heat insulation material of solar heat absorption pipe.

Description

technical field [0001] The invention relates to thermal insulation materials, especially fiber cotton. Background technique [0002] At present, the thermal insulation materials on the market are mainly rock wool, glass wool and other materials that are harmful to the human body and the respiratory system. Although rock wool has the characteristics of fire prevention and heat preservation, glass wool has good fire resistance. The improvement of health care awareness highlights the pollution of rock wool and glass wool to public places and the harm to the human body. Therefore, there is an urgent need for a new type of environmentally friendly cotton that can replace rock wool, glass wool, sponge and other traditional harmful insulation, flame retardant, and sound absorption. , especially the environmental protection products of various product packaging, interior decoration and thermal insulation materials in various fields that are in close contact with people's life, daily...
