Problems solved by technology

[0003] And the waste PVC materials that will be recycled to produce new PVC sheets are easy to produce unattractive appearance, and more raw materials after aging will lead to a short service life of new PVC sheets, and due to insufficient decomposition of raw materials in the production process Thoroughly, so it will cause the new PVC material to be more toxic, so the quality cannot reach the quality of the original material

Abstract

The invention discloses a composite PVC sheet produced by using waste PVC. The composite PVC sheet is prepared from the following materials in parts by weight: 90 to 100 parts of old PVC reclaimed material, 50 to 60 parts of PVC resin, 5 to 10 parts of a plasticizer, 3 to 8 parts of light calcium carbonate, 10 to 15 parts of paraffin, 0.5 to 1 part of a mildew preventive, 3 to 5 parts of a stabilizer, 5 to 9 parts of an ultraviolet absorbent, 20 to 30 parts of plant fiber, 15 to 20 parts of butyl rubber, 2 to 3 parts of a dispersing agent, 0.1 to 1 part of a coloring agent, 1 to 2 parts of a reinforced and modified filler and 15 to 25 parts of a vinyl chloride grafted copolymer with ethylene-vinyl acetate resin as a substrate. According to the composite PVC sheet produced by using the waste PVC disclosed by the invention, reasonable raw materials are selected and the proportion of the raw materials is reasonable, so that the prepared composite PVC sheet has the advantages of good high-temperature resistance and good anti-resonance effect; in addition, tests show that the conventional service life of damping sheets can also be achieved in a high temperature working environment; the obtained composite PVC sheet also has good water resistance, high viscosity, a shock absorbing function and a noise eliminating function.

Description

technical field [0001] The invention relates to the technical field of automobile brake system materials, in particular to a composite PVC sheet produced from waste PVC. Background technique [0002] PVC material is widely used because of its good processing performance, flex crack resistance and strong corrosion resistance. Due to the substantial increase in the cost of raw materials in the PVC industry in recent years, PVC manufacturers must start with reducing raw materials in order to reduce production costs and improve economic benefits. [0003] And the waste PVC materials that will be recycled to produce new PVC sheets are easy to produce unattractive appearance, and more raw materials after aging will lead to a short service life of new PVC sheets, and due to insufficient decomposition of raw materials in the production process Thoroughly, so it will cause the new PVC material to be more toxic, so the quality cannot reach the quality of the original material. Cont...
