Abstract
The present invention provides a kind of processing technologys of automotive battery pallet, are related to automobile component processing technique field.A kind of automotive battery pallet is directly produced by the raw material that glass fibre, PP and necessary additive collectively constitute and is obtained；The raw material with can root product requirement be correspondingly adjusted；Glass fibre average length reaches 10-12mm in the finished product；Tensile strength is 1.3 times of SMC material intensity.Production technology material selection of the invention flexibly, can the different additive of on-line control, fiber content and fibre length to reach the requirements of final products；The mechanical performances such as shock resistance, the creep resistant of product and heat resistanceheat resistant performance are good；Semi-finished product are removed in the light weight online production technique of product, and raw material and production cost are low, product recoverable, with short production cycle.
Description
Technical field
The present invention relates to a kind of processing technologys of automotive battery pallet.
Background technique
With the development of automotive light weight technology technology, plastics and its composite material are applied to the range of auto parts and components increasingly
Extensively, opposing metallic material has lightweight (density there was only steel density 1/6~1/7), at low cost, easy processing etc. significant excellent
Gesture is especially in inside gadget on automobile and is widely applied, wherein most widely used is fibre reinforced composites.And
Long glass fiber-reinforced polypropylene product relative to other fibre reinforced materials as SMC product, GMT product have high production efficiency, at
The advantages such as this low, easy reclaiming, product lighter (density there was only steel density 1/6~1/7), performance be strong, gradually replace SMC
And GMT, become the developing direction of current automotive industry fibre reinforced composites.Long glass fiber-reinforced polypropylene adds at home at present
The situation that work technique is lower still in technical level, special equipment falls behind, at home the exploitation on auto parts and components, design and answer
With only a small amount of product.
Summary of the invention
For above situation, the present invention provides a kind of automotive battery pallet processing technology, to push long glass fiber reinforced
The research and development and development of PP Production Technology and product structure at home improve long glass fiber-reinforced polypropylene production technology application water
It is flat, fibre reinforced composites are further widened in the application of field of automobile parts and components, catch up with and surpass foreign same type for home products
Product is made contributions.
To achieve the goals above, technical scheme is as follows:
A, polymer base particles and additive are transported in gravity mixing weighing unit, according to automotive battery support
The mechanical property requirements of disk carry out the mixture of material；
B, the good raw material of mixture is sent into double screw extruder and is plasticized, the mixture of melting passes through a film mould
Capitiform is fed directly into the opening of twin-screw mixer extruding machine at the thin polymer film similar to waterfall, the thin polymer film；
C, while the mixture of melting forms the thin polymer film of similar waterfall by a sheeting die, glass fibers
Rove is tieed up by specially designed creel, the top that thin polymer film is introduced in after preheating, dispersion with it is thin
Film converges to be entered in double screw extruder together；
D, rove is cut by screw rod in double screw extruder, and they are mildly mixed into fritting polymer it
In, it is then sent directly into the material charging region of compacting tool set and forms, after molded curing molding, demoulding.
The invention has the advantages that raw material selection is flexibly, can be contained by the different additive of on-line control, fiber
Amount and fibre length reach the requirement of final products；The mechanical performances such as shock resistance, the creep resistant of product and heat resistanceheat resistant performance are good, quality
Gently；Material can produce the more complex product of structure；Online manufacturing method semi-finished product are removed, and raw material and production cost are low, and
Product recoverable, it is with short production cycle.
