Abstract

The invention relates to a U-PVC pipe with a high impact resistant performance. The U-PVC pipe comprises the following components in parts by weight: 100 parts of PVC-SG8 resin, 1 to 10 parts of ABS resin powder, 1 to 10 parts of solubilizer, 1 to 10 parts of heat stabilizer, 0.1 to 5 parts of lubricant, 0 to 5 parts of processing modifier, 5 to 50 parts of filling agent, and 0.5 to 5 parts of titanium dioxide. The pipe comprises ABS powder, the chain sections of butadiene rubber of ABS can absorb the impact energy, and thus the pipe can well resist the impact. At the same time, the amount of added ABS powder is little, the influence on the processing property and product stability is small, and the production is barely affected. A proper amount of CPE is added to increase the capacity of the ABS/PVC system, in the microscopic view, the phase separation degree is decreased, and thus the impact resistant effect is enhanced.

Description

A kind of high-impact U-PVC pipe fitting
Technical field
The present invention relates to a kind of U-PVC pipe fitting, specifically relate to a kind of high-impact U-PVC pipe fitting.
Background technology
U-PVC universal pipe, pipe fitting are a kind of products that Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) starts in the nineties to promote the use of, light weight, inexpensive, corrosion-resistant is had compared with galvanized steel tubing, cast iron pipe fittings, the advantages such as flow velocity is fast and easy for installation are desirable water supply pipe in building regeneration products.
But the poor heat stability of U-PVC pipe fitting work in-process, melt viscosity is large, and plasticizing poor fluidity, must add the additives such as stablizer, fluidizer, lubricant in production application, could machine-shaping.Current U-PVC pipe fitting auxiliary material adds more, but shock resistance is poor.Therefore, research and develop that a kind of auxiliary material addition is few and the U-PVC pipe fitting of shock resistance successful is very necessary.The present invention produces thus.
Summary of the invention
For the above-mentioned technical problem of prior art, the object of this invention is to provide a kind of high-impact U-PVC pipe fitting, this U-PVC pipe fitting auxiliary material addition is few, and good impact resistant effect.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of high-impact U-PVC pipe fitting, comprises following component: PVC-SG8 resin 100 parts, ABS resin powder 1-10 part, solubilizing agent 1-10 part, thermo-stabilizer 1-10 part, lubricant 0.1-5 part, modifier 0-5 part, weighting agent 5-50 part and titanium dioxide 0.5-5 part.
Described solubilizing agent is one or more in chlorinatedpolyethylene, Chlorinated Polypropylene III or chlorinated polybutylenes.
Described thermo-stabilizer is inorganic lead salt composite thermal stabilizer.
Described lubricant is one or more in metal soap, stearic acid and derivative thereof, polyester or saturated hydrocarbons lubricant.
Described modifier is one or more in Process Technology of Polymer properties-correcting agent or common polychloroethylene processing modifier.
Described Process Technology of Polymer properties-correcting agent is CALCIUM ACRYLATE analog copolymer.
Described common polychloroethylene processing modifier is chlorinatedpolyethylene.
Described weighting agent is one or more in the inorganic calcium salt after calcium carbonate, calcium sulfate, silicate or activation.
Described titanium dioxide is one or both of Rutile type Titanium Dioxide or anatase thpe white powder.
Beneficial effect of the present invention is as follows:
High-impact U-PVC pipe fitting of the present invention, adds ABS powder, by the sorption of divinyl rubber segment impact energy in ABS, reaches good shock resistance effect; ABS powder addition is few, affects less on processing characteristics and product stability, less to Influence of production; By adding the addition of C PE to reach the compatibilization effect to ABS/PVC system, on microcosmic, minimizing system is separated degree, makes anti-impact effect better.
Embodiment
Below in conjunction with specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
embodiment 1-8
Solubilizing agent in the present embodiment 1-8 can be chlorinatedpolyethylene, one or more in Chlorinated Polypropylene III or chlorinated polybutylenes, thermo-stabilizer can be inorganic lead salt composite thermal stabilizer, lubricant can be metal soap, stearic acid and derivative thereof, one or more in polyester or saturated hydrocarbons lubricant, modifier can be one or more in acrylics multipolymer (ACR) Process Technology of Polymer properties-correcting agent or common polyvinyl chloride (CPE) modifier, weighting agent can be calcium carbonate, calcium sulfate, silicate or activation after inorganic calcium salt in one or more, titanium dioxide is one or both of Rutile type Titanium Dioxide or anatase thpe white powder, act as product to brighten.
comparative example 1
PVC-SG8 resin: 100 parts
Solubilizing agent chlorinatedpolyethylene (CPE): 2.5 parts
Inorganic lead salt thermo-stabilizer: 6.0 parts
Lead stearate lubricant: 1.2 parts
ACR processes activator: 4.0 parts
Titanium dioxide: 2.4 parts
Activated Calcium carbonate weighting agent: 20.0 parts
performance test
One, drop impact experiment is adopted to carry out shock strength test.Experiment condition is as follows:
1, drop hammer quality: 1.25kg, height of the fall: 1.0m.
test result
Comparative example 1 pipe fitting breakage rate: 40%;
The pipe fitting breakage rate of embodiment 1-8: 66.7%.
Breakage rate reduces: (66.7%-40%)/40%=66.75%
2, drop hammer quality: 1.5kg, height of the fall: 1.0m.
test result
Comparative example pipe fitting breakage rate: 30%;
Embodiment 1-8 pipe fitting breakage rate: 50%.
Breakage rate reduces: (50%-30%)/30%=66.67%
That is, after adding ABS resin powder, the breakage rate of U-PVC pipe fitting reduces about 66.7%.
Two, tension test.
Comparative example material extending elongation at break average out to 126.83%, embodiment 1-8 material extending elongation at break average out to 114.05%.
That is, adding along with ABS resin powder, Materials Fracture elongation decreases.
The present invention reaches target, and the shock resistance compared to current pipe fitting improves 50%-200%.
Above-described embodiment only illustrates inventive concept of the present invention for explaining, but not the restriction to rights protection of the present invention, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should fall into protection scope of the present invention.
