Background technique
Quick, life Energy and comfort is transmitted to meet the information of society, the mortality of electric appliance is accelerated, and generates therewith a large amount of
Electronic apparatus rubbish, the producer improve the quality of product as far as possible to extend the service life of product, adapt to consumer to production
The rigors of product.But large percentage is hardware and plastic casing in the electric appliance of recycling, and the recycling dispersion of plastics is not easy
Degradation, re-works the features such as performance is poor, keeps the cost recovery of plastics high, utilization rate is low.
Currently, electric appliance casing majority is by ABS resin and corresponding auxiliary agent machine-shaping, ABS is typical thermoplasticity
Plastics are that they can re-work molding with the maximum difference of thermosetting plastics.But the plastic casing of recycling passes through
Use in several years, surface discolouration, degradation have no use value.PBT has crystal property, so having preferable resistance to organic
Solvent corrosion and mechanical property.Crystalline plastic is since strand is regular and does not have polar group, more difficult combination with decorative surfaces；And
ABS is easy friction in process and forms electrostatic, as some coating, be easily coated on table because of polarized itrile group on strand
Layer, and be not easy to fall.
The above two classes Compatibility in Plastics is poor, and the surface that is such as mixed can generate blistering, mercury line, seriously understands peeling, so
The compatibility of two kinds of plastics is very big to the performance and appearance effects of product.

Step 2, in parts by weight, by 100 parts of ABS particle, 4-8 parts of methyl methacrylate, 4-8 parts of styrene, peroxidating two
0.1-0.5 parts of isopropylbenzene mixing, mixture are sent into dual-screw-stem machine and carry out fusion-grafting, make on pelleter after graft is cooling
Grafted pellets 1,2- methylene chloride is dissolved, is subsequently poured into methanol, sediment is dried in vacuo after filtering, and is obtained pure by grain
Grafted pellets after change；
Step 3, in parts by weight, 4-10 parts of grafted pellets 100 parts of ABS particle, step 2 being obtained, 40-60 parts of PBT, MBS
0.3-0.7 parts of 2-6 parts, 1-3 parts of alumina silicate fibre and lubricant squeeze on the twin screw extruder after mixing in a high speed mixer
Be granulated out to get.
Preferably, in step 1 ABS particle partial size≤3mm.
Preferably, in step 2 temperature of dual-screw-stem machine be 170-210 DEG C, revolving speed 90-100rpm.
Preferably, grafted pellets and 1 in step 2,2- methylene chloride, methanol amount ratio be 1 g:30 mL:100 mL.
