Novel regenerative environment-friendly rubber moulding board and manufacturing method thereof

Abstract

The invention adopts substrate materials of waste plastics, waste rubber tires, pulverized fuel ashes, waste sheet particles and synthetic fibers, goes through the steps of plastication, molding, cooling and other steps, produces outer products composed mainly of waste plastics and pulverized fuel ashes as well as inner products composed mainly of waste rubber particles and waste sheet particles, and then cools the outer and the inner produces with high pressure by a molding composite method; after the natural abscise, a composite board is prepared with the outer layer as plastic-ash material and the inner layer as rubber-wood material. The invention selects some waste raw materials for matching, adopts a special production method and manufactures a novel reproductive environment-friendly rubber molding board which has the advantages of good plasticity, extensibility, stability, etc., and has good popularizing and application value.

Description

technical field [0001] The invention is a new building material developed according to the ten new technology requirements of the Ministry of Construction and market demand, especially a new type of recycled and environmentally friendly rubber formwork and its manufacturing method. Background technique [0002] As we all know, most of the templates currently on the market use cement, sand and water as raw materials. They are mixed and stirred to form a slurry, which is injected into the model with the predetermined shape of the template, and it is gradually solidified and maintained to reach the allowable strength. A concrete structure after the formwork is removed, and the concrete structure can be used in engineering. Formwork is an essential equipment in construction engineering. At present, the formwork surface materials used in engineering usually include wooden plywood formwork and steel formwork. Due to the high cost of steel molds. Due to the defects of heavy weig...

AI Technical Summary

Problems solved by technology

Heavy weight, easy to deform, easy to oxidize and rust, and the shape cannot be changed on site, and its elasticity is worse than that of wooden plywood formwork, so that there are fewer and fewer occasions where steel forms are used

At present, the wooden formwork used in the market is mainly made of trees, which is soft in texture, not resistant to various bumps on the construction site, and has a short service life. Generally, it can only be recycled three to four times, and it is difficult to demould after use. It is easy to leave the oil stains used for easy demoulding, which will cause adverse effects on the ecological environment

Wooden formwork is easy to absorb water, which makes the moisture ratio of concrete unbalanced, resulting in poor concrete surface quality and insufficient strength, and these formworks cannot be reused, which is not only a great waste of forest resources, but also waste due to inability to reuse It is difficult to clean up the material, these characteristics make the wooden formwork urgently need a new type of recycled environmental protection formwork to replace
