Abstract
The invention provides the application of thermoplastic elastic bodies in vehicle fittings, wherein metals or engineering plastics are made into stocks of vehicle fittings to be gained, then the metal blocks or the engineering plastic blocks are arranged in a die, finally the thermoplastic elastic bodies is coated on the metal blocks or the engineering plastic blocks via mechanography. The mechanography comprises injection molding, extrusion molding, foaming molding and the like. The application of thermoplastic elastic bodies provided by the invention in the vehicle fittings adopts the mechanography to recombine the thermoplastic elastic bodies outside the vehicle fittings blocks which are needed to be gained, thereby gaining more rigid frameworks and vehicle fittings which have certain soft handle feeling or mechanical elasticity or insulation, and further being equipped with safety, transfigurement and practicability. The metal blocks or the engineering plastic blocks impacted in the intermediate portion occupy part of work piece volume, thereby leading materials at lower price to replace materials at higher price, and one time molding forming is simpler than sticking composite technology to lead the manufacture costs of the vehicle fittings with the same property to be reduced.
Description
What technical field the present invention relates to is the application of a kind of thermoplastic elastomer (TPE) in auto parts machinery, belongs to technical field of macromolecular composite compound, also belongs to auto parts machinery manufacturing technology field.
It is a kind of with rubber and thermoplastic characteristic that background technology thermoplastic elastomer (TPE) (Thermoplastic elastomer) is also referred to as thermoplastic elastomer (Thermoplastic rubber), the high resiliency that shows rubber at normal temperatures, macromolecular material that again can plasticizing forming under the high temperature also is called for short TPR or TPE.Because it has high resiliency, need not vulcanize, easy-formation, reusable edible, energy-conservation, etc. advantageous characteristic.Now become rubber, plastics a kind of new material afterwards, obtained swift and violent development all over the world.The dual performance of rubber that thermoplastic elastomer (TPE) had and plastics and broad characteristic make it can be applicable to auto industry and make multiple auto parts machinery, it is reported that kind of an auto parts machinery has used thermoplastic elastomer (TPE) surplus in the of existing 30.But as can be seen, adopting thermoplastic elastomer (TPE) to make auto parts machinery at present all is to be raw-material with single thermoplastic elastomer (TPE), or with binding agent thermoplastic elastomer (TPE) is compound on the other materials, comes with some shortcomings on performance, price from the report.
Summary of the invention is at above-mentioned deficiency, technical problem to be solved by this invention is that thermoplastic elastomer (TPE) and metal or other hard materials (mainly being engineering plastics) are had is good compound, so that the application technology of the high performance thermoplastic elastomer (TPE) of a kind of low price in auto parts machinery to be provided.
The application of thermoplastic elastomer (TPE) provided by the invention in auto parts machinery, earlier metal or engineering plastics are made auto parts machinery blank to be obtained, again metal or engineering plastics blank are placed mould, with mechanography thermoplastic elastomer (TPE) is coated on outside metal or the engineering plastics blank at last.Said mechanography comprises technologies such as injection moulding, extrusion modling and foaming.
The application of thermoplastic elastomer (TPE) provided by the invention in auto parts machinery, adopt mechanography directly thermoplastic elastomer (TPE) to be compound to outside the auto parts machinery blank of required acquisition, to obtain that the auto parts machinery that certain soft feel or mechanical elasticity or insulation are arranged again than hard frame is arranged, have more safe aesthetic utility.Middle metal that embeds or engineering plastics blank a part of workpiece volume that accounted for, make lower price material substitution the material of higher price, and once molded and shaped simpler than the bonding combination process, the manufacturing cost of the auto parts machinery with same performance is descended.In addition, the present invention does not use the more sharp environmental protection of binding agent.
The application of thermoplastic elastomer (TPE) provided by the invention in auto parts machinery, before molded, in the thermoplastic elastomer based material, add weight content below 20%, diameter is at the thermosetting plastics particle of 0.5-3 millimeter, be used for the auto parts machinery with holds such as fabrication direction dish, handle, handle, made holds sense preferably.
The application of thermoplastic elastomer (TPE) provided by the invention in auto parts machinery, before molded, in the thermoplastic elastomer based material, add weight content at the luminescent powder below 5%, be used to make gadget in instrument board, handle, switch or other cars, so that when driving at night, use observation easily.
The specific embodiment 1, in automotive seat handrail skeleton pattern, annotate body formed automobile armrest skeleton with ABS, this skeleton is placed automotive seat handrail mould, be injected in the mould with thermoplastic elastomer (TPE), make thermoplastic elastomer (TPE) be wrapped in skeleton and form the automotive seat handrail outward.Gained automotive seat handrail has hard skeleton and flexible extexine.
2, in the thermoplastic elastomer (TPE) particle, add weight content 12%, diameter is at 1.3 millimeters bakelite particle, join in the extruder stub bar after mixing all.Compound is heated in bringing-up section, and thermoplastic elastomer (TPE) melting and not melting of bakelite are clamp-oned in the steering wheel mould that is equipped with the steel frame of handwheel through barrel is constantly mixed, make and make the steering wheel that is coated with the thermoplastic elastomer (TPE) that contains solids.
3, when thermoplastic elastomer (TPE) is mixing, add weight content at 3% luminescent powder, common granulation.Make instrument board with this material, the instrument board of noctilucence performance must be arranged.
4, earlier with thermoplastic elastomer (TPE) injection-molded one deck metal tube outside, the reusable heat thermoplastic elastic molded one deck that foams outside it must the compartment handle, and is soft flexible.
Claims (3)
1. the application of thermoplastic elastomer (TPE) in auto parts machinery, it is characterized in that earlier metal or engineering plastics being made auto parts machinery blank to be obtained, again metal or engineering plastics blank are placed mould, with mechanography thermoplastic elastomer (TPE) is coated on outside metal or the engineering plastics blank at last.
2. the application of thermoplastic elastomer (TPE) as claimed in claim 1 in auto parts machinery, it is characterized in that before molded in the thermoplastic elastomer based material, adding weight content below 20%, diameter is at the thermosetting plastics particle of 0.5-3 millimeter.
3. the application of thermoplastic elastomer (TPE) as claimed in claim 1 in auto parts machinery is characterized in that adding weight content at the luminescent powder below 5% in the thermoplastic elastomer based material before molded.
