The flexible pipe of PVC is inexpensive, generally acknowledge it is also apply maximum outdoor pipe materials at present, but there are some defects in the flexible pipe that existing PVC hose tubing is made, such as expose to the weather for a long time out of doors, aging ratio is very fast, and radiation resistance is poor, and the way overcoming this defect at present adds antioxidant with UV light absorber, but the material added costly, causes PVC hose production cost higher.
Summary of the invention
The object of this invention is to provide the preparation technology of a kind of radioprotective communication tubing, not only greatly can improve the radiation resistance of tubing, and cost compare is low, be applicable to applying compared with prior art, strong shock resistance, and product component is cheap, the market competitiveness is large.
The technical solution used in the present invention is as follows:
A preparation technology for radioprotective communication tubing, includes following processing step:
1), by weight, be made up of following raw material: organosilicon modified crylic acid resin 58-60 part, stearoyl benzoyl methane 3-5 part, zinc oxide 2.2-4 part, trimeric cyanamide 3.5-5.5 part, clorafin 3.5-5.5 part, MBS resin 14-17 part, Fluorspar Powder 2-3 part, light calcium carbonate 1.5-1.7 part, lubricating auxiliary agent 1.5-2.5 part, nickel metal powder 0.5-1.2 part;
2), Fluorspar Powder, light calcium carbonate, nickel metal powder are pulverized through Ultrafine Grinding, the concentration of the steeping fluid in impregnation chamber is 8 ~ 12%, the activator of steeping fluid is selected from dimethylbenzene or acetic acid primary isoamyl alcohol, the temperature of steeping fluid is 48 ~ 50 DEG C, dipping time is 5-8h, powder after dipping, through washing, spraying dry, obtains powder siccative;
3), by powder siccative mix with remaining feed composition, stir and be heated to 90-100 DEG C, insulation 2-3 hour, is chilled to 30 DEG C, and insulation 1.2-1.8 hour, reheats to 105-120 DEG C, and insulation 1-1.5 hour, is cooled to normal temperature with 4-6 DEG C/min;
4), finally single screw extrusion machine is added, at 182-188 DEG C of plasticizing forming, the pipe of extrusion moulding, enter in the forming mould of rotation through longitudinal stretching, then through vacuum forming, namely cross directional stretch is shaping obtains rigidity communication tubing, and its longitudinal stretching is than being 0.8-1.2, and cross directional stretch is than being 1.3-1.4.
Powder siccative is mixed with remaining feed composition, stirs and be heated to 95 DEG C, be incubated 2.5 hours, be chilled to 30 DEG C, be incubated 1.5 hours, reheat to 112 DEG C, be incubated 1.2 hours, be cooled to normal temperature with 5 DEG C/min.
Raw material of the present invention with organosilicon modified crylic acid resin, MBS resin for major ingredient, with the addition of nickel metal powder, lubricating auxiliary agent simultaneously, not only greatly can improve the radiation resistance of tubing, and cost compare is low, be applicable to applying compared with prior art, strong shock resistance, and product component is cheap, the market competitiveness is large.
