Abstract
The invention discloses a preparation method of an environment-friendly heat-preservation rubber-plastic product, which comprises the steps of adding raw materials into a mixer in proportion, and uniformly stirring to obtain a mixture; adding the mixture into a reaction kettle for mixing reaction, then extruding and granulating by using a double-screw extruder to obtain modified granules, and grinding the modified granules into powder; and then mixing the polyurethane, the powder, the foaming agent, the emulsifier and phenolsulfonic acid, putting the mixture into a stirrer, uniformly stirring the mixture, injecting the mixture into a mold, mixing and foaming the mixture, curing the mixture, and demolding the cured product to obtain the environment-friendly heat-preservation rubber-plastic product. The method of the invention adopts the recovered waste PVC plastic to be modified after being crushed as the production raw material, thereby not only realizing the harmless and resource utilization of the waste plastic and relieving the shortage of plastic resources, but also being environment-friendly, pollution-free, recyclable and beneficial to the society. Meanwhile, the prepared rubber and plastic product is waterproof, moistureproof, heat-insulating, long in service life, simple in preparation process, safe and environment-friendly in production process and suitable for large-scale industrial production.
Description
Technical Field
The invention relates to a preparation method of an environment-friendly heat-preservation rubber and plastic product.
Background
The rubber industry is an important component of chemical industry in China, the basic raw materials of the rubber industry are natural rubber and synthetic rubber, and various chemical processing aids are required to be added in order to manufacture rubber products meeting the requirements of actual use performance and improve the processing technological performance. At present, the general production of rubber and plastic products uses nitrile rubber and polyvinyl chloride resin as main materials, other auxiliary materials are added for high-temperature blending, then a vulcanizing agent and a foaming agent are added for vulcanization foaming, and finally the preparation of the rubber and plastic products is realized. The rubber plastic material has the excellent performances of softness, winding resistance, cold resistance, heat resistance, flame retardance, water resistance, low heat conductivity coefficient, shock absorption, sound absorption and the like, and can be widely applied to the industries of central air conditioners, buildings, chemical engineering, vehicles, electric appliances and the like. Polyvinyl chloride, abbreviated as PVC in English, is an initiator of vinyl chloride monomer in peroxide, azo compounds and the like; or a polymer polymerized by a free radical polymerization mechanism under the action of light and heat. PVC has been the most widely used plastic in the world and is used in a very wide range of applications. The product can be widely applied to the aspects of building materials, industrial products, daily necessities, packaging films, bottles, foaming materials, sealing materials, fibers and the like. Due to the wide application of PVC materials, waste materials are very low, the PVC materials are difficult to degrade naturally, and the PVC materials are rarely effectively utilized in the prior art. The waste PVC plastic is a great public nuisance for environmental pollution, but if waste is changed into valuables, the environmental pollution problem can be changed, and the healthy development of the plastic industry is promoted, so the invention provides a preparation method of an environment-friendly heat-preservation rubber and plastic product by combining the formula design and the process of a packing box, the waste PVC plastic is regenerated to prepare a raw material, and the rubber and plastic product prepared by processing the waste PVC plastic has excellent mechanical properties and meets the use requirements of the rubber and plastic product.
Disclosure of Invention
The invention aims to provide a preparation method of an environment-friendly heat-preservation rubber and plastic product.
In order to realize the aim, the invention provides a preparation method of an environment-friendly heat-preservation rubber-plastic product, which comprises the following steps:
