Process for manufacturing and paving sidewalk rubber floor mat

Abstract

The invention discloses a process for manufacturing and paving a sidewalk rubber floor mat. The process flow comprises preparation of raw materials, prefabrication of reclaimed rubber panels, manufacture of sidewalk groundwork, pavement of the rubber panels and the like. The steps are as follows: uniformly stirring the prepared colloidal particles and polyurethane glue in a mixer according to a certain ratio to prefabricate into the reclaimed rubber panels; cleaning a basic road surface and then smearing an MDI environmentally friendly adhesive; and finally cutting the rubber panels into the thickness of 3.2-6mm as required, roll-pressing, checking and then trimming to put the obtained rubber floor mat into service in 48 hours. The process of the invention takes waste rubber products such as waste tires and the like as raw materials and has no secondary pollution, thus effectively solving the problems of resource recovery and utilization of the waste rubber products such as the waste tires and the like; and the process is applied to sidewalk pavement, thus effectively reducing the incidence of accidents.

Description

technical field [0001] The invention relates to a technology for effectively recycling and utilizing resources, in particular to a process for making and paving rubber floor mats for sidewalks that can recycle and reprocess waste tires and other harmful rubber products for paving sidewalks. Background technique [0002] China is a big country with rapid development of the rubber industry. The total consumption of rubber accounts for 22% of the world. At the same time, the waste tires and waste rubber products produced after use also increase at an equal rate. The volume exceeds 112 million pieces, about 3 million tons, and China has become the country with the largest waste rubber resources in the world; after years of research abroad, the utilization method of waste tire rubber materials is: crushing old car tires into crumbs , add chemical binders, and then bake to make rubber products. The domestic waste rubber processing skills are generally recycled into reclaimed rubbe...

Problems solved by technology

[0002] China is a big country with rapid development of the rubber industry. The total consumption of rubber accounts for 22% of the world. At the same time, the waste tires and waste rubber products produced after use also increase at an equal rate. The volume exceeds 112 million pieces, about 3 million tons, and China has become the country with the largest waste rubber resources in the world; after years of research abroad, the utilization method of waste tire rubber materials is: crushing old car tires into crumbs , add chemical binders, and then bake to make rubber products. The domestic waste rubber processing skills are generally recycled into reclaimed rubber, rubber powder, oil refining, and other direct utilization. Among them, waste tires are used for oil refining and Incineration power generation and other treatment methods, due to the inability to solve the problem of waste gas and wastewater discharge in the production process, have caused serious secondary environmental pollution problems. Although the country has explicitly banned them, most of the waste tires are still consumed in local methods. In terms of oil refining, the environmental pollution is shocking. As the country pays more and more attention to environmental protection, the utilization of a large number of waste tires has become an imminent thing; The reason is that the road is slippery, fission and other problems, and the safety factor is low. Once it falls, it will cause unnecessary harm to people, especially the elderly and children. In bad weather such as wind, rain, and snow, the possibility of accidents is greater, and it may even endanger Life, and the rubber pavement has excellent thermal expansion and contraction, and is not easy to freeze, which greatly reduces the possibility of accidents; at present, there is a blank in China to recycle rubber products such as waste tires and use them on sidewalks. Under the premise of polluting the environment and low energy consumption, rational use of waste rubber resources is a top priority, and if a technology can be invented to recycle and utilize a large number of waste tires and other rubber products and use it for paving sidewalks, it will definitely bring considerable social and economic benefits
