Abstract

The invention relates to the field of automobile part preparation, in particular to a preparation method of an automobile headlamp shell. The preparation method comprises the following steps that 1, 30-50 parts by weight of polypropylene resin, 1-3 parts by weight of glass fibers, 1-2 parts by weight of mica powder, 0.5-1 part by weight of nano-bismuth powder, 0.5-1 part by weight of sodium persulfate, 1-2 parts by weight of talcum powder and 0.1-0.3 part by weight of rare earth lanthanum are mixed and then heated to 220 DEG C-260 DEG C, the temperature is kept at 220 DEG C-260 DEG C for 1-2 h, and then a melt mixture is prepared; 2, the melt mixture prepared in the step 1 is injected into a double-screw extruder, stirred, mixed and extruded into a die cavity through melting, cooling is performed, and the automobile headlamp shell is formed. According to the prepared automobile headlamp shell, the lamp shell is easily taken out through lubricating oil, and the impact strength, the hardness and the abrasive resistance of the lamp shell are improved through the used material components.

Description

A kind of preparation method of car lighting lamp lamp housing
Technical field
The present invention relates to auto parts and components preparation field, be specifically related to the preparation method of a kind of car lighting lamp lamp housing.
Background technology
Current car lighting lamp lamp housing, owing to being positioned at headstock or the tailstock, is easily subject to clash into and damage;And it is by relatively During little grazing, easily wear and tear.
Summary of the invention
For solving problem of the prior art, it is an object of the invention to provide a kind of improve impact strength, improve hardness and The preparation method of the car lighting lamp lamp housing of anti-wear performance.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that: the preparation side of a kind of car lighting lamp lamp housing Method, it is characterised in that comprise the steps:
(1) by acrylic resin 30-50 part, glass fibre 1-3 part, 1-2 part mica powder, bismuth meal end 0.5-1 part, sodium peroxydisulfate 0.5-1 part, Pulvis Talci 1-2 part, Rare Earth Lanthanum 0.1-0.3 part mixing post-heating to 220-260 degree Celsius, and it is maintained at 220-260 Degree Celsius 1-2h, prepares molten mixture, and described number is parts by weight;(2) molten mixture that step (1) is prepared Injecting double screw extruder, stirring mixing also melt extrudes to die cavity, and cooling forms car lighting lamp lamp housing.
Die cavity in step (2) is the die cavity that preparation forms car lighting lamp lamp housing.
In step (2), it is cooled to natural cooling.
In step (1), by acrylic resin 40 parts, 2 parts, 2 parts mica powders of glass fibre, bismuth meal end 1 part, sodium peroxydisulfate 1 Part, Pulvis Talci 2 parts, Rare Earth Lanthanum 0.1 part mixing post-heating to 260 degrees Celsius, and it is maintained at 260 degrees Celsius of 1-2h.
In step (2), it is cooled to use circulating cooling water cooling.
In step (2), cavity surface one layer of lubricating oil of coating.
Car lighting lamp lamp housing prepared by the present invention, lubricating oil makes lamp housing be easier to take out, the material composition of use, Improve the impact strength of lamp housing, hardness and wearability.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention made concrete introduction.
Embodiment 1
(1) by acrylic resin 30 parts, 1 part, 1 part mica powder of glass fibre, 0.5 part of bismuth meal end, sodium peroxydisulfate 0.5 part, Talcum 1 part of powder, Rare Earth Lanthanum 0.1 part mixing post-heating to 260 degrees Celsius, and it is maintained at 260 degrees Celsius of 1-2h, prepare molten mixture, Described number is parts by weight;
(2) molten mixture that step (1) prepares injecting double screw extruder, stirring mixing also melt extrudes to die cavity, Cooling, cavity surface one layer of lubricating oil of coating, shape car lamp housing of illumination lamp.
