Description
Technical field
The invention belongs to used in construction drainage material technical field, particularly relate to a kind of hard PVC water shoot and preparation method thereof.
Background technology
PVC drain pipe be a kind of with polyvinyl chloride (PVC) resin for raw material, the not plastic pipe of plasticizer-containing.Plastics tubing is widely used in the fields such as city water supply and sewage, building water supply and drainage, hot water service, heat supply heating abroad.In numerous tubing kind, the consumption of PVC pipeline has comparative advantage.In developed country, pvc pipe consumption generally accounts for 70 ~ 80% of plastics tubing market, and China's pvc pipe only accounts for about 50% of the total amount of plastics tubing.Wherein pipe fitting is about 1:8 with the consumption ratio of tubing.In the past in 10 years, Chinese Plastics pipe market average growth rate per annum is that 20%, 2000,2002 and 2003 annual production reach 700,000 ~ 800,000 t, 1,300,000 t and 1,500,000 t respectively, and rate of increase is 15%, and wherein pvc pipe accounts for 55%, PE pipe and accounts for 40%.2010, in national newly-built, renovating and enlarging engineering, construction drainage pipeline 80% adopted plastics tubing, and building rainwater drainage pipe 70% adopts plastics tubing, and the plastics tubing of urban discharging pipeline uses and reaches 30%.Expect 2015, the water shoot in national New Dwelling 85% adopts plastics tubing.Along with the pay attention to day by day of Environmental protection, in the five-year, country will drop into huge fund in network of drains construction, this means that the developing market space of underground drainage plastics pipes is strengthened.
In recent years, along with the increase of PVC drain pipe consumption, people have also had higher demand to PVC quality and function, and PVC dead meal is piled up for a long time simultaneously, not only causes environmental pollution, especially the wasting of resources.Given this, the present inventor, through test of many times, proposes a kind of hard PVC water shoot.
Summary of the invention
The object of the invention is to: a kind of hard PVC water shoot and preparation method thereof is provided, solve the deficiency that existing PVC drain pipe exists.
To achieve these goals, the present invention adopts following technical scheme:
A kind of hard PVC water shoot, is characterized in that: be made up of the Raw material processing of following weight part: 100 parts, waste PVC particle, one package stabilizer 3.5 ~ 5 parts, light calcium carbonate 7 ~ 9 parts, polyethylene wax 0.2 ~ 0.4 part, butyl stearate 1.5 ~ 2.5 parts, stearic acid 0.3 ~ 0.5 part, titanium dioxide 2.5 ~ 4 parts, 0.5 ~ 0.8 part, whitening agent, tribasic lead sulfate 1 ~ 2 part, lead stearate 1 ~ 1.5 part, titanate coupling agent 1.2 ~ 1.8 parts.
As preferably, described a kind of hard PVC water shoot, is characterized in that: be made up of the Raw material processing of following weight part: 100 parts, waste PVC particle, one package stabilizer 4.2 parts, light calcium carbonate 8 parts, polyethylene wax 0.3 part, butyl stearate 2 parts, stearic acid 0.4 part, titanium dioxide 3.2 parts, 0.7 part, whitening agent, tribasic lead sulfate 1.5 parts, lead stearate 1.2 parts, titanate coupling agent 1.5 parts.
The preparation method of described hard PVC water shoot is: according to said ratio, is mixed by raw material under 120 DEG C of conditions, then extrusion moulding under 180 DEG C of conditions, and wherein, extrusion pressure is 41MPa, and extrusion capacity is 45kg/h.
Compared with prior art, beneficial effect of the present invention is:
Hard PVC water shoot of the present invention adopts waste PVC particle to be raw material, cheap and be easy to get, and not only realize turning waste into wealth, economic environmental protection, also eliminates waste plastic and pollute, more achieve good economic benefit; After testing, this hard PVC water shoot tensile strength and shock strength higher; This hard PVC water shoot is not only applicable to water service pipe pipeline, also can be used for and Food Contact goods.
