Preferably, the filler is titanium dioxide.
Compared with prior art, what the present invention realized uses CPVC composition will the utility model has the advantages that the present invention exempts to be granulated to be molded
CPVC resin, stabilizer, low-density non-oxidized polyethylene wax, high density oxidized polyethylene wax, impact modifier, processing aid,
Antioxidant and filler compounding, the composition of acquisition need not move through granulating working procedure, are used directly for injection molding and obtain
Good physical performance, highly polished product.
Specific embodiment
Meet CPVC resin, stabilizer, low-density non-oxidized polyethylene wax, high density oxidized polyethylene wax, processing aid,
Antioxidant and filler type and dosage are constant, select different medicaments as impact modifier respectively, the component of selection and
The CPVC composition of dosage such as table 1, acquisition carries out injection molding, and it is as shown in table 2 to obtain properties of product.

Comparative example 3 | 1471 | 104.6 | 57.2 | 8.1 | It is high |
National standard | 1450~1650 | ≥103 | ≥50 | ≥8.1 |
From Table 2, it can be seen that the CPVC composition for selecting ACR to obtain as impact modifier, carries out injection molding, processability
Can be good, its vicat softening temperature of CPVC injecting products obtained is 104.3 DEG C, but tensile yield strength and the punching of notch overarm arm
Hit intensity is below national standard, can not normal use;Select CPE as CPVC injecting products made from impact modifier,
Notch overarm arm impact strength is improved, but tensile yield strength is still very low, not up to national standard;MBS is selected to make
For the CPVC composition that impact modifier obtains, processing performance and product strength obtained are up to state standards.
Meet CPVC resin, stabilizer, impact modifier, processing aid, antioxidant and filler type and dosage not
Become, low-density non-oxidized polyethylene wax, high density oxidized polyethylene wax difference or mixing is added, the component and dosage of selection are such as
Table 3, the performance of the CPVC composition of acquisition such as table 4.

Comparative example 4 | 1471 | 104.5 | 46.2 | 7.7 | It is high |
Comparative example 5 | 1471 | 104.2 | 56.7 | 8.2 | It is low |
National standard | 1450-1650 | ≥103 | ≥50 | ≥8.1 |
As can be seen from Table 4, low-density non-oxidized polyethylene wax is used alone as lubricant, CPVC obtained in comparative example 4
Product glossiness is high, but due to delaying plasticizing so that product tensile yield strength is lower, properties of product are lower than national standard;It is right
High density oxidized polyethylene wax is used alone as lubricant in ratio 5, accelerates plasticizing, the vicat softening temperature of product stretches
Yield strength, notch overarm arm impact strength are up to state standards, but glossiness reduces, and reduces the application of CPVC product
Field;Comparative example 3 has used low-density non-oxidized polyethylene wax and high density oxidized polyethylene wax simultaneously, balances the light of product
Damp degree and performance, resultant effect is more preferably.Therefore low-density non-oxidized polyethylene wax and high density oxidized polyethylene wax compounding is selected to make
With.
