Problems solved by technology

Due to the limitation of casting process and anti-theft factors, metal tree pit cover plate has complicated installation process and has been greatly limited in application; reinforced concrete cover plate can prevent theft, but its water permeability and air permeability are poor, which has certain effects on tree growth. Influence; the thermal stability of the plastic cover is poor, and it is easy to age and damage after long-term sunlight; the wooden cover has poor strength and corrosion resistance due to the characteristics of the wood itself, and its service life is short
If there is no cover board or gravels are piled directly in the tree pit, it will cause a lot of urban dust and pollution

Abstract

The invention discloses a method for manufacturing a reclaimed rubber thread plate by utilizing rubber threads produced by polishing for large waste rubber tyre retreading and application of the reclaimed rubber thread plate as a tree pit cover plate. The method comprises the following specific steps: raw material preparation: collecting large engineering tyres, preparing the rubber threads by utilizing a polisher and sieving the rubber threads; and reclaimed rubber thread plate preparation: adding additives, mixing the rubber threads with the additives and stirring the mixture, and carrying out hot-pressing and vulcanizing to prepare the plate. The reclaimed rubber thread plate prepared by the method has the following beneficial effects: the thicker rubber threads are adhered by adhesives and are hot-pressed and vulcanized to prepare the bottom layer of the rubber plate, the thinner rubber threads are adhered by adhesives and are hot-pressed and vulcanized to prepare the surface layer of the rubber plate, and multiple layers of rubber thread structures tightly form the reclaimed rubber plate; therefore the reclaimed rubber thread plate has the characteristics of low cost, good tensile elasticity and strong air and water permeability; and when being used in the green tree pit, the reclaimed rubber thread plate can be processed on the site according to the specific position requirement of the tree and is simple and convenient to construct.

Description

technical field [0001] The present invention relates to a manufacturing method and application of a regenerated rubber wire board, in particular to a method for manufacturing a regenerated rubber wire board by using the rubber wire refurbished and polished of giant waste rubber tires and the use of the regenerated rubber wire board for tree pit cover plates use. [0002] The "regenerated rubber wire board" in the present invention is a regenerated board made from the rubber wire polished during the retreading process of giant waste tires. Background technique [0003] At present, in my country, more than 1 million tons of large-scale engineering tires are eliminated by major mines every year. This kind of large engineering tire has a diameter of 1.2 to 4 meters and a weight of 1.2 to 5.5 tons. In my country, it is mainly imported. The production of one requires about 4 tons of high-quality rubber raw materials. After this tire is used normally, more than 70% of its rubber ...
