Domestic Automotive Industry flourishes in recent years, turns into Global Auto production and marketing big country, as petroleum resources are nervous, oil price
Rise steadily, automotive light weight technology turns into the key subjects of China Automobile Industry, and the application of engineering plastics is automotive light weight technology
Inevitable choice.Plasticization of Automobile degree shows industry manufacture level.Foreign Automobile inner and outer decorative parts are all using working of plastics.Automobile using
Plastics are more than 160 kilograms/.The exploitation and application of nonmetal structure part are carried forward vigorously in recent years, with metal phase ratio, engineering plastic
Many advantages, such as material has light specific gravity, corrosion-resistant, easy-formation, is especially suitable for maker complex component, and production efficiency is high.As
Automobile structure engineering plastics, it is largely glass or the fine enhancing modification of nylon of carbon.Glass fiber enhanced nylon has intensity high, resistance to
The features such as warm nature can be good, moderate.
Cooling fan is one of critical component for ensureing automotive safety operation.Technique mistake is removed using metal manufacture cooling fan
Journey is complicated, and low into production efficiency, metal fan easily gets rusty, weight is big.With fiberglass reinforced PP manufacture cooling fan can realize once into
Type, and the performance such as corrosion-resistant, high temperature resistant, impact strength, flexural strength is good, meets automobile requirement.But PP and glass
Consistency problem between fibre be present, influence the performance quality of final products.
The content of the invention

Toughener in the step (2) is ethylene-octene copolymer POE, SBS elastomer
SBS, at least one of the terpolymer EPDM, ethylene-vinyl acetate EVA of ethene, propylene and alkadienes maleic acid
Acid anhydride graft polymers.
The addition of alkali-free glass fibre in the step (2) is total prescription quality (i.e. toughener and nylon base-material
Gross mass) 20-25%.
The rotating speed of dual-screw-stem machine in the step (2) is 300-350rpm, and temperature is 235-255 DEG C.
Feed proportioning uses automatic material-dispensing system dispensing.
Beneficial effect
(1) present invention improves the combination phase between glass fibre by carrying out coupling processing on nylon base-material surface
Capacitive；
(2) blanking of the invention in bielectron Weightlessness balance, ensure that blending is granulated uniform and stable, under being stirred than traditional-handwork
Material, which is granulated, has better performance quality；
(3) automatic material-dispensing system of the present invention carries out dispensing, ensures that formula materials processing is accurate, is turned into efficiently and continuously
Industry, while greatly reduce cost of labor.
