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:
The present invention relates to backplate at the bottom of a kind of manned vehicle driving engine of RPP resin material, be used for backplate at the bottom of the economical manned vehicle.
Background technology:
Backplate at the bottom of the driving engine, has the ground that prevents anomalous upheaval in the face of the direct impact of driving engine, isolated from functions such as ground-surface mud, sandstone are involved in motor bearing belt, the air-conditioning compressor, and help the driving engine bottom to form steady air flow, the noise that produces when reducing high-speed cruising.
Backplate adopts UPGF (SMC) material at the bottom of the driving engine of little red flag family car, exist product heaviness, cost height and UPGF (SMC) MAT'L recycling narrow range problems such as (can only be used as filler at present), can not satisfy the requirement of falling heavily, falling cost and improving the recyclable degree of utilization of material.
Summary of the invention:
The object of the present invention is to provide backplate at the bottom of a kind of manned vehicle driving engine of RPP resin material, be to be base material with glass fibre/mineral powder RPP resin (PP+MD+GF) composite material, it has advantages such as glass fiber content is low, lightweight, low price, die press technology for forming after the preheating of employing sheet material.Help falling and heavily fall cost, be suitable for backplate at the bottom of the economical manned vehicle.
Technical scheme of the present invention is achieved in that backplate at the bottom of a kind of manned vehicle driving engine of RPP resin material, it is characterized in that: be made up of by following parts by weight glass fibre/mineral powder RPP resin (PP+MD+GF) composite material:,
Polypropylene: 68-78
French talc: 22-25
Glass fibre: 3-7
Its end backplate mould pressing process is as follows:
1) glass fibre/mineral powder RPP resin PP+MD+GF gets the raw materials ready
With the weight of calculating, to get the raw materials ready with weighing, sheet material cutting should be cut off with plate shearing machine, or with the hacksaw cutting, and is should heart wheel sheet when with emery wheel cracked; The sheet material size should with goods quite or less than normal, during every LFT material progressive die tool, should take between two block of material for more than two centimetres;
2) preheating
The sheet material that weighs up is put into the baking oven preheating, should not surpass two-layer stacking in the case, this is for the easy heat penetration of material, and minimizing time of heat, preheating temperature is 200～220 ℃, and the time is 3～4 minutes, and the too high meeting of temperature decomposes to smolder influences performance, temperature is crossed low or heating can not influence the product pressing result thoroughly, is very soft condition after the sheet material preheating is good;
3) compacting
The sheet material that preheating is good takes out from baking oven, correctly puts into mould as early as possible, if number of sheets is many, answers multi agent cooperation, puts into mould according to prior preordering method, in case put matched moulds immediately well, 40～55 ℃ of mold temperatures, dwell time 45sec.
Good effect of the present invention is to adopt the concavo-convex groove structure around end backplate flat board, to increase end backplate product integral rigidity, reduces distortion and stress; Have (lighter by 70%) in light weight, cost low (than backplate cost at the bottom of the SMC low 70%), meet the automobile environment-protection laws and regulations requirement than backplate at the bottom of the SMC, it is the recyclable and utilization again of product, therefore backplate of this end can be applicable to have boundless application prospect on the multiple vehicle.
