Embodiment 1

[0021] Polypropylene: 68, talcum powder: 25, glass fiber: 7 are weighed and prepared according to parts by weight, and the material sheet is obtained by calendering. The sheet cutting should be cut with a cutting machine, or cut with a hacksaw. The heart wheel should be broken; the size of the sheet should be equal to or smaller than the finished product. When each piece of LFT material enters the mold, the gap between the two materials should be more than two centimeters;

[0022] Then put the weighed sheet into the oven to preheat. It is not advisable to stack more than two layers in the oven. This is to make the material easy to heat through and reduce the heating time. The preheating temperature is 200-220°C and the time is 3-4 minutes. , If the temperature is too high, it will decompose and smoke and affect the performance. If the temperature is too low or the heating is impermeable, it will affect the product pressing effect. After the sheet is preheated, it will be very ...

Embodiment 2

[0025] Polypropylene: 74, talcum powder: 23, glass fiber: 3 are weighed and prepared according to parts by weight, and the material sheet is obtained by calendering. The sheet cutting should be cut with a cutting machine, or cut with a hacksaw. The heart wheel should be broken; the size of the sheet should be equal to or smaller than the finished product.

Embodiment 3

[0029] Polypropylene: 70, talcum powder: 25, glass fiber: 5 are weighed and prepared according to parts by weight, and the material sheet is obtained by calendering. The sheet cutting should be cut with a cutting machine, or cut with a hacksaw. The heart wheel should be broken; the size of the sheet should be equal to or smaller than the finished product. When each piece of LFT material enters the mold, the gap between the two materials should be more than two centimeters;

[0030] Then put the weighed sheets into the oven to preheat. It is not advisable to stack more than two layers in the oven. This is to make the material easy to heat through and reduce the heating time. The preheating temperature is 200-220°C and the time is 3-4 minutes. , If the temperature is too high, it will decompose and smoke and affect the performance.

Abstract

The invention relates to a reinforced polypropylene resin material for passenger vehicle engine bottom guard plates, which is characterized by comprising a glass fiber/mineral powder reinforced polypropylene resin (PP+MD+GF) composite material in the following parts by weight: 68-78 parts of polypropylene, 22-25 parts of talcum powder and 3-7 parts of glass fiber. A mold pressing process of the bottom guard plate comprises PP+MD+GF material preparation, preheating and pressing. The invention has the advantages of low glass fiber content, light weight, low price and the like, and the molding process of mold pressing after plate preheating is used. The reinforced polypropylene resin material is beneficial to cost reduction and is applicable to economical passenger vehicle engine bottom guard plates.

Description

Technical field: [0001] The invention relates to a passenger car engine bottom guard plate made of reinforced polypropylene resin, which is used for the economical passenger car bottom guard plate. Background technique: [0002] The bottom guard plate of the engine has the functions of preventing the abnormally raised ground from directly colliding with the engine, isolating the mud and gravel from the ground from being involved in the engine bearing belt, and the air-conditioning compressor, etc., and helping the lower part of the engine to form a stable airflow to reduce the high-speed running noise produced. [0003] The engine bottom guard plate of Xiaohongqi series vehicles is made of UPGF (SMC) material, which has problems such as bulky parts, high cost and narrow recycling range of UPGF (SMC) material (currently it can only be used as filler), which cannot meet the weight reduction requirements , Reducing costs and increasing the recyclability of materials. Inventi...
