Description
Technical field
The invention belongs to technical field of polymer materials, especially a kind of heat-resistant impacts bumper material.
Background technology
In the prior art, partial automobile bumper is that have the advantages that intensity is high, but be easy hair using made of metal
Change shape, easily get rusty, to pacify Installed display lamps difficult, and bumper bar made of plastics then has the shortcomings that impact strength is poor.It is answered
Ensure:It is less than 4km/h when colliding speed, is unlikely to that irremediable structure is caused to destroy;When colliding speed less than 8km/h,
It will not cause heavy losses.Plastics bumper bar is substantially instead of made of metal bumper.Raw material is as making bumper
Plastics, should have good toughness, lower temperature resistance, weatherability, solvent resistance (because surface will paint) and japanning jail
Degree.Plastics used based on MODIFIED PP, but MODIFIED PP there is also shock resistances low, heat-resistant aging and dimensional stability compared with
The defect of difference, it is difficult to meet the requirement of bumper bending strength and impact strength equilibrium.Those skilled in the art's divination by means of the milfoil is to be developed
A kind of bumper material that novel heat-resistant high impact-resistant is hit.
Invention content
In view of the above-mentioned problems, the present invention is intended to provide a kind of bumper material of heat-resistant impact.

Part;B liquid:It is 14-17 parts of styrene, 1-2 parts of co-catalyst, attapulgite 6-8 parts organically-modified;
2nd step, reaction injection molding:A liquid, B liquid are uniformly mixed, under nitrogen protection, closed insurance is injected at 65 DEG C
In thick stick mold, polymerisation, rear curing process 1min are carried out;
The major catalyst is tungsten hexachloride, by tungsten hexachloride in molar ratio 1:Tungsten hexachloride and tert-butyl benzene is added in 1 ratio
Phenol dissolves in acetone, is stirred to react 20h at 65 DEG C, boils off acetone and obtain major catalyst;The co-catalyst is alkyl aluminum;
The organically-modified attapulgite is prepared using following steps:
The phosphoric acid solution immersion treatment 30min for being 15% by attapulgite use quality score, then dries attapulgite, will
Attapulgite uses treatment fluid immersion treatment 20min, treatment fluid to be prepared using following methods:By dialkyl group carbazole salt, 16
Alkyl pyridinium chloride/a- cyclodextrin, calgon are 1 by weight:0.5:2 ratio mixing, is then added mixture weight
The aqueous acetone solution of 20 times of amount, is prepared into treatment fluid.
Preferably, the A liquid:85 parts of dicyclopentadiene monomer, 27 parts of polystyrene, 0.08 part of major catalyst, stabilizer
1.2 part;B liquid:15 parts of styrene, 1.7 parts of co-catalyst, 6.5 parts of organically-modified attapulgite.
The present invention has the following advantages compared with prior art:
The present invention is shifted poly- in a kind of preparation process for the bumper material that heat-resistant impacts using the open loop of dicyclopentadiene
The strongly exothermic the characteristics of can causing radical polymerizable vinyl monomer simultaneously closed, and polystyrene is added and is blended, it designs
A kind of interpenetrating polymer networks structure new method of new ring-opening metathetic polymerization synchronized compound structure-controllable.Using organically-modified recessed
Convex stick soil carries out intercalation synthesis polymerization to polymer, promotes the heat resistance of material, heat resistance improves significantly.
