Abstract
The invention discloses an insulated PVC plastic comprising the compositions in parts by weight of: 50 parts of PVC resin; 10-30 parts of VAGH; 10-15 parts of stearic acid; 3-5 parts of plasticizer; 2.5 parts of titanium oxide; 1.5 parts of nano calcium carbonate; 0.6 part of antioxidant; 1-3 parts of heat stabilizer; 0.01 part of lubricant. In the invention, the VAGH and the stearic acid are mixed with the PVC resin in order to increase the thermal stability of the PVC plastic and improve the insulation performance thereof. In this way, the insulated PVC plastic can be widely used in a low-frequency insulation field. The invention is wide in application scope and simple in process and convenient in production.
Description
Technical field
The present invention relates to a kind of insulation PVC plastics, belong to the macromolecule chemical industry technical field.
Background technology
The PVC industry in whole world development rapidly; have a extensive future; the potentiality that each state all has an optimistic view of PVC with and to the benefit of ecotope; PVC is just superior with it, particular performances proves that to common people its effect and status are that any other products all can't replace; social development needs it; environment protection needs it, and it is the inexorable trend of our civilization of human society progress.The PVC plastics can be made the low frequency insulating material, its chemical stability, but because the thermostability of polyvinyl chloride is relatively poor, long-time heating can cause decomposing, and emits HCL gas, makes the polyvinyl chloride variable color, so its range of application is narrower, influence the range of application of PVC plastics.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of Heat stability is good is provided, the insulation PVC plastics of applied range.
Technical scheme: a kind of insulation PVC plastics of the present invention, the parts by weight of its component are:
Polyvinyl chloride resin: 50 parts;
