Abstract
The invention relates to a long glass fiber reinforced polypropylene resin engine skid plate of a passenger vehicle, which is characterized in that the engine skid plate is prepared by using the long glass fiber reinforced polypropylene resins as a raw material through the steps of fusing the long fiber reinforced thermoplastics (LFT) into sheets; putting the obtained sheets into a mould for 40sec at the normal temperature according to a preset method; and carrying out mold stripping, wherein the pressure of the mould is 22MPa, and the pressure keeping time of the mould is 18sec. Because the whole forming process of the engine skid plate is implemented only through a single heating course, the energy consumption is low; meanwhile, the intermediate links such as storing, transporting and preheating prepreg materials are reduced, therefore, the energy consumption and manual work are saved, and the production cost is low.
Description
Technical field:
The present invention relates to backplate at the bottom of a kind of manned vehicle driving engine of long glass fiber reinforced profax resin.
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 long glass fiber reinforced profax resin, be to be base material with long glass fiber reinforced profax resin (LFT-D) composite material, need not preheating during online production and can in mould, compression molding go out end backplate goods, forming process has only the course of a single heating, and energy consumption is lower; Reduced intermediate links such as preimpregnation material storage, transportation and preheating, saved energy consumption and artificial, productive costs is lower; The goods producer can determine raw MAT'L and proportioning voluntarily according to the different demands of goods, batching degree of freedom height; Wearing and tearing to fiber in the forming process are less, can guarantee the length of glass fibre better, make end article have more excellent mechanical property and outward appearance; To the former wearing and tearing still less; The utilization again of waste material is reclaimed in easier realization.
Technical scheme of the present invention is achieved in that backplate at the bottom of the manned vehicle driving engine of long glass fiber reinforced profax resin, it is characterized in that: be made up of by following parts by weight long glass fiber reinforced profax resin (LFT-D) composite material:
Polypropylene: 72-78 glass fibre: 20-26
Its end backplate technology is as follows:
1) long glass fiber reinforced profax resin LFT gets the raw materials ready
According to end backplate geomery, calculate the weight and the size of required LFT sheet material, directly cut LFT fusion sheet material from general extruder extrusion;
2) compacting
With LFT fusion sheet material, put into mould according to prior preordering method, in case put matched moulds immediately well, mold temperature normal temperature, die pressure 22MPa, dwell time 18sec gets final product depanning about 40sec; For preventing the product distortion, just the depanning product should rationally be placed, and can be placed on if necessary on the simple shaper, and cooling is taken off again slightly.
Good effect of the present invention is to have favorable shock resistance, decay resistance and excellent low-temperature properties with the protective case that Blanket strengthens the thermoplastic composite compression molding, and weight is lighter, it not only can keep driving engine clean, but also can reduce the resistance of air, the noise that produces when reducing running car; It adopts the concavo-convex groove structure around end backplate flat board, to increase end backplate product integral rigidity, reduce distortion and stress; Have in light weight, lighter by 74% than backplate at the bottom of the SMC, cost is low, hanging down 73%, meet the automobile environment-protection laws and regulations requirement than backplate cost at the bottom of the SMC is the recyclable and utilization again of product, and because the online production of LFT-D material, directly the fusion sheet material can be delivered in the mould, saved middle buying material and the fore-warming operation of sheet material, enhanced productivity.
Long glass fiber reinforced profax resin (LFT-D) composite property satisfies backplate requirement at the bottom of the motorcar engine.
Long glass fiber reinforced profax resin (LFT-D) composite property
The specific embodiment:
The present invention will be further described below in conjunction with embodiment:
Embodiment 1:
At first with polypropylene: 78, glass fibre: 22, weigh by weight and get the raw materials ready, long glass fiber reinforced profax resin (LFT) is extruded 115 ℃ of extrusion temperatures through general extruder.
According to end backplate geomery, calculate the weight and the size of required LFT sheet material, directly cut long glass fiber reinforced profax resin LFT molten sheet code material from the extrusion of specific extruder.
With the long glass fiber reinforced profax resin LFT fusion sheet material that downcuts, put into mould again according to prior preordering method.In case put matched moulds immediately well, mold temperature is a normal temperature, die pressure 22MPa, dwell time 18sec, molding cycle 40sec.For preventing the product distortion, just the depanning product should rationally be placed, and can be placed on if necessary on the simple shaper, and cooling is taken off again slightly.
Embodiment 2:
At first with polypropylene: 75, glass fibre: 25, weigh by weight and get the raw materials ready, long glass fiber reinforced profax resin (LFT) is extruded 249 ℃ of extrusion temperatures through general extruder.
According to end backplate geomery, calculate the weight and the size of required LFT sheet material, directly cut long glass fiber reinforced profax resin LFT molten sheet code material from the extrusion of specific extruder.
With the long glass fiber reinforced profax resin LFT fusion sheet material that downcuts, put into mould again according to prior preordering method.In case put matched moulds immediately well, mold temperature is a normal temperature, die pressure 22MPa, dwell time 18sec, molding cycle 40sec.For preventing the product distortion, just the depanning product should rationally be placed, and can be placed on if necessary on the simple shaper, and cooling is taken off again slightly.
