preparation example Construction

[0012] The invention provides a method for preparing an automobile air-conditioning heat insulation pad, wherein the preparation method comprises:

[0013] (1) Cut the aluminum silicate fiber into long strips with a length of 2-6cm, then mix the aluminum silicate fiber with silica airgel, aluminum sol, and potassium hexatitanate whisker, and add solvent and stir evenly , forming a mixed liquid M;

[0014] (2) Pour the mixed liquid M in the step (1) into a molding mold for drying to obtain a heat insulation pad; wherein,

[0015] Relative to 100 parts by weight of aluminum silicate fibers, the amount of silica airgel is 120-150 parts by weight, the amount of aluminum sol is 30-50 parts by weight, and the amount of potassium hexatitanate whiskers is 15-35 parts by weight share.

[0016] Through the above technical scheme, the present invention mixes aluminum silicate fiber with silica airgel, aluminum sol, and potassium hexatitanate whisker, and adds a solvent to stir evenly, ...

Embodiment 1

[0025] The aluminum silicate fiber is cut into strips with a length of 2 cm, and then the aluminum silicate fiber, silica airgel, aluminum sol and potassium hexatitanate whisker are mixed according to the weight ratio of 100:130:35:20 Mix in proportion, add deionized water and stir evenly to form a mixed solution M; vacuum filter the mixed solution M, pour it into a molding mold and dry it at 80°C for 10 hours, and then dry it at 400°C for 1 hour to obtain a thermal insulation Pad A1. Among the above raw materials, the density of aluminum silicate fiber is 100kg / m 3 , whose diameter is 1 mm.

Embodiment 2

[0027] The aluminum silicate fiber is cut into strips with a length of 6 cm, and then the aluminum silicate fiber, silica airgel, aluminum sol and potassium hexatitanate whisker are mixed according to the weight ratio of 100:140:45:30 Mix in proportion, add ethanol and stir evenly to form a mixed solution M; vacuum filter the mixed solution M, pour it into a molding mold and dry it at 120°C for 15 hours, and then dry it at 450°C for 2 hours to obtain a thermal insulation mat A2 . Among the above raw materials, the density of aluminum silicate fiber is 120kg / m 3 , whose diameter is 3 mm.

Abstract

The invention discloses an automobile air conditioner heat insulation mat and a preparation method thereof. The preparation method comprises the following steps: cutting aluminum silicate fibers into strips in the length of 2cm to 6cm, then mixing the aluminum silicate fibers with silicon dioxide aerogel, alumina sol and potassium hexatitanate whisker, adding solvent, uniformly stirring to form a mixed solution M; pouring the mixed solution M into a forming mold, and drying to obtain the heat insulation mat. For 100 parts by weight of aluminum silicate fibers, the consumption of the silicon dioxide aerogel is 120 to 150 parts by weight, the consumption of alumina sol is 30 to 50 parts by weight, and the consumption of the potassium hexatitanate whisker is 15 to 35 parts by weight. The heat insulation mat prepared by utilizing the preparation method does not produce peculiar smell in a high temperature environment and is unlikely to deform and drop after being subjected to the high temperature influence for a long time.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto air conditioner heat insulation pad and a preparation method thereof. Background technique [0002] In the automotive air conditioning system, the exhaust air duct is often made of plastic products. If it is exposed to high temperature for a long time, it will cause the exhaust air duct to soften. Therefore, the inner wall of the air duct is often provided with a layer of heat insulation pad. The traditional heat insulation pad will produce peculiar smell in high temperature environment, and it is easy to deform under the influence of high temperature for a long time, causing it to fall off from the inner wall of the air duct. Contents of the invention [0003] The object of the present invention is to provide a heat insulation pad for automobile air conditioners and a preparation method thereof. The heat insulation pad prepared by the preparation method will not produce pecul...
