The processing of CPVC injecting products.
Above-mentioned pellet can be used for the processing of CPVC injecting products, but CPVC composition have passed through granulation before injection molding
Process has that degree of plasticification is bad when being otherwise molded, to influence the physical property and finish of product.However, being granulated
Process increases energy consumption when business manpower, the investment of equipment and production to a certain extent, increases being produced into for product
This.It needs one kind at present to exempt to be granulated injection molding CPVC composition, to simplify the manufacturing procedure of CPVC injecting products.
Summary of the invention
In order to solve the problems, such as to need to be granulated preplasticizing before CPVC composition is molded in the prior art, the purpose of the present invention is
One kind is provided to exempt to be granulated injection molding CPVC composition.
To achieve the goals above, the present invention adopts the following technical scheme: one kind is exempted to be granulated injection molding CPVC composition, by
Following group of parts by weight is grouped as: 100 parts of CPVC resin, 4-6 parts of stabilizer, and low-density non-oxidized polyethylene wax 0.5-1.5
Part, 0.5-1.5 parts of high density oxidized polyethylene wax, 5-10 parts of impact modifier, 3-6 parts of processing aid, antioxidant 1-1.5
Part, 2-5 parts of filler.
Low-density non-oxidized polyethylene wax: density is between 0.9-0.92g/cm at 25 DEG C3Polyethylene wax；High density oxidation
Polyethylene wax: density is between 0.96-0.98g/cm at 25 DEG C3Oxidized polyethylene wax, wherein oxidized polyethylene wax be polyethylene
Wax is made through oxidation technology.

Preferably, the antioxidant is antioxidant 1076.
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.
Table 1
| CPVC resin (100 Part) | Stabilizer (4 parts) | Low-density is non-oxide poly- Ethylene waxes (0.5 part) | High density oxidic polyethylene Wax (0.5 part) | Impact modifier (8 parts) | Processing aid (2 parts) | Antioxidant (1.5 Part) | Filler (3 parts) | |
| Comparative example 1 | Chlorinity is 66% CPVC resin | Octyl mercaptan organotin Stabilizer 17MOK | AC-617A | AC-316A | ACR PA-101 | PA-20 | 1076 | Titanium dioxide |
| Comparative example 2 | —— | —— | —— | —— | CPE 135A | —— | —— | —— |
| Comparative example 3 | —— | —— | —— | —— | MBS TH-21 | —— | —— | —— |
Table 2
| Density (kg/m3) | Vicat softening temperature DEG C | Tensile yield strength minimum (MPa) | Notch overarm arm impact strength (A type, 23 DEG C, kJ/m2) | Glossiness | |
| Comparative example 1 | 1472 | 104.3 | 44.1 | 7.1 | It is high |
| Comparative example 2 | 1471 | 104.5 | 47.7 | 8.0 | It is high |
| 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.
Table 3
| CPVC resin | Stabilizer | Low-density is non-oxide Polyethylene wax | High density oxidation Polyethylene wax | Impact modifier | Processing helps Agent | It is anti-oxidant Agent | Filler | |
| Comparative example 3 | The CPVC that chlorinity is 66% Resin (100 parts) | Octyl mercaptan Organotin Stabilized 17MOK(4 parts of agent) | AC-617A (0.5 part) | AC-316A (0.5 part) | MBS TH-21 (8 parts) | PA-20 (2 parts) | 1076 (1.5 parts) | Titanium dioxide (3 parts) |
| Comparative example 4 | The CPVC that chlorinity is 66% Resin (100 parts) | Octyl mercaptan Organotin Stabilized 17MOK(4 parts of agent) | AC-617A(1 parts) | Nothing | MBS TH-21 (8 parts) | PA-20 (2 parts) | 1076 (1.5 parts) | Titanium dioxide (3 parts) |
| Comparative example 5 | The CPVC that chlorinity is 66% Resin (100 parts) | Octyl mercaptan Organotin Stabilized 17MOK(4 parts of agent) | Nothing | AC-316A (1 part) | MBS TH-21 (8 parts) | PA-20 (2 parts) | 1076 (1.5 parts) | Titanium dioxide (3 parts) |
Table 4
| Density (kg/m3) | Vicat softening temperature DEG C | Tensile yield strength minimum (MPa) | Notch overarm arm impact strength (A type, 23 DEG C, kJ/m2) | Glossiness | |
| Comparative example 3 | 1471 | 104.6 | 57.2 | 8.1 | It is high |
| 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.
