Abstract

The invention provides composite wax for a PVC pipeline and a preparation method of the composite wax, and belongs to the technical field of composite waxs. The composite wax for the PVC pipeline is prepared from, by weight, 20-30 parts of paraffin, 15-25 parts of VP copolymer, 10-15 parts of vegetable wax, 20-35 parts of oxidized polyethlene wax, 5-10 parts of stearic acid, 6-12 parts of filler, 3-7 parts of polyolefin, 10-20 parts of ethylene bis stearamide, 10-30 parts of pigment powder. 1-2 parts of a dispersing agent, 2-5 parts of a defoaming agent and 1-4 parts of a thickening agent. According to the scheme, the paraffin, the vegetable wax, the oxidized polyethlene wax and the stearic acid are compounded for use, and the prepared composite wax can well improve the overall uniformity and lubricity, so that the performance of the PVC pipeline can be improved when the composite wax is applied to the PVC pipeline.

Description

technical field [0001] The invention belongs to the technical field of composite wax, and in particular relates to a composite wax for PVC pipes and a preparation method thereof. Background technique [0002] PVC is the abbreviation of PVC, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. Wax is generally added during its production to improve its performance. [0003] When the existing wax is used for PVC pipes, each component is applied to the surface of the PVC pipe...
