Embodiment

[0032] A preparation method for an anti-fog headlight material, comprising the following steps:

[0033] Step 1: Add 60-80 parts of polyphenylene ether, 5-20 parts of flow modifier, 5-15 parts of toughening agent, 1-5 parts of interface modifier, 1-10 parts of dry neutralizer, and other additives 0.5-2 parts are mixed in a mixer for 1-3min to obtain a mixture.

[0034] Step 2: Add the mixture obtained in the above step 1 into the twin-screw extruder through the hopper; add the reinforcement into the twin-screw extruder from the side feeding port; granulate at a temperature of 250-350°C, and the screw speed is 400- 800r / min, get the headlight material.

[0035] The polyphenylene ether is one of isotactic polystyrene, syndiotactic polystyrene, and high-impact polystyrene graft-modified polyphenylene ether, preferably high-impact polystyrene graft-copolymerized phenyl ether.

[0036] The flow modifier is one of polybutadiene, high-impact polystyrene, nylon 6, and polybutylene ...

Abstract

The invention discloses an anti-fogging headlight material and a preparation method thereof. The material disclosed by the invention comprises the following components in parts by weight: 60-80 partsof polyphenyl ether, 5-20 parts of a flow modifier, 5-15 parts of a flexibilizer, 5-20 parts of an enhancer, 1-5 parts of an interfacial modifier, 1-10 parts of a drying neutralizer and 0.5-2 parts ofother additives. The invention further discloses a preparation method of the anti-fogging headlight material. The material disclosed by the invention solves the headlight fogging problem, and has thecharacteristic of low material dispersion property. In addition, the anti-fogging headlight material disclosed by the invention further has moisture resistance and high rigidity, and the requirementthat the lamp assembly is not influenced by strong vibration is met. Furthermore, due to good flowability of the material, the requirement that the thickness of the parts of the headlight assembly isreduced can be met, and the manufacturing cost is reduced. The product further has the characteristics such as light weight, excellent dimensional stability, short molding cycle, high finished productyield and the like.

Description

technical field [0001] The invention relates to a microfoaming film material and a preparation method thereof, in particular to an anti-fog headlight material and a preparation method thereof, and belongs to the technical field of polymer materials. Background technique [0002] When the gas produced by the plastic parts in the lamp adheres to the wall of the lamp bowl, the fogging problem of the car lamp will occur, and the lamp will fade; on the other hand, the fogging of the headlight may also be caused by the high air humidity, causing the air The water vapor in the lamp condenses in the headlights, causing fogging. In this way, it will not only affect the appearance of the lamps, but also threaten the driving safety due to the deterioration of the light distribution. Headlights produced by the world's leading companies will have this problem. [0003] At present, the main solution is to put a special desiccant for car lights in the car lights. However, this method ca...
