preparation example Construction

[0013] The invention provides a method for preparing an air outlet panel of an automobile air conditioner, wherein the preparation method comprises: mixing polyethylene, polypropylene, azodicarbonamide, phenolic resin, an emulsifier and a plasticizer, heating and molding to obtain Panel body M; mix wood fiber, polyester fiber and isocyanate to form colloid N; apply colloid N on the surface of panel body M, and obtain an air outlet panel after baking, wherein, relative to 100 parts by weight of polyethylene , the consumption of polypropylene is 50-100 parts by weight, the consumption of azodicarbonamide is 20-45 parts by weight, the consumption of phenolic resin is 30-45 parts by weight, the consumption of emulsifier is 2-10 parts by weight, plasticizing The consumption of the agent is 2-10 parts by weight, the consumption of the wood fiber is 80-120 parts by weight, the consumption of the polyester fiber is 80-100 parts by weight, and the consumption of the isocyanate is 20-55 ...

Embodiment 1

[0021] After mixing 100g of polyethylene, 65g of polypropylene, 30g of azodicarbonamide, 35g of phenolic resin, 4g of octylphenol polyoxyethylene ether and 4g of dioctyl phthalate, heating and molding to obtain the panel body M; 90g of wood fiber, 85g of polyester fiber and 35g of isocyanate are mixed to form colloid N; Colloid N is coated on the surface of panel body M, and after baking, air outlet panel A1 is obtained, wherein the weight average molecular weight of polyethylene is 12000, poly The weight average molecular weight of propylene is 8000, the baking temperature is 50° C., and the baking time is 10 minutes.

Embodiment 2

[0023] After mixing 100g of polyethylene, 85g of polypropylene, 35g of azodicarbonamide, 40g of phenolic resin, 8g of benzyldimethylphenol polyoxyethylene ether and 8g of dioctyl phthalate, heating and molding to obtain a panel blank Body M; 110g wood fiber, 95g polyester fiber and 45g isocyanate are mixed to form colloid N; colloid N is coated on the surface of panel body M, and after baking, air outlet panel A2 is obtained, wherein the weight average molecular weight of polyethylene The weight average molecular weight of polypropylene is 12000, the baking temperature is 75°C, and the baking time is 25min.

Abstract

The present invention discloses an automobile air conditioning vent panel and a preparation method thereof. The preparation method comprises: mixing polyethylene, polypropylene, azodicarbonamide, phenolic resin, an emulsifier and a plasticizer; heating and molding to obtain a panel blank M; mixing wood fiber, polyester fiber and isocyanate to form a colloid N; coating the colloid N on the surface of the panel M; and baking to obtain the vent panel. The invention solves the problem of weak sound insulation effect of the vent panel.

Description

technical field [0001] The invention relates to automobile air conditioner accessories, in particular to an automobile air conditioner air outlet panel and a preparation method thereof. Background technique [0002] With the rapid growth of the automobile industry, the auto parts industry has also developed rapidly. As an important component to improve the comfort of automobiles, automobile air conditioners have been recognized by the majority of automobile manufacturers and consumers. Usually, the wind speed of the air outlet of the automobile air conditioner is adjustable. When the wind speed increases, the noise of the air outlet also increases. At present, the sound insulation effect of the existing air outlet panel is relatively poor. Contents of the invention [0003] The invention provides an air outlet panel of an automobile air conditioner and a preparation method thereof, which solves the problem of poor sound insulation effect of the existing air outlet panel. ...
