Rubber latex refers to the colloidal emulsion formed by polymer particles dispersed in water, also known as latex. It is customary to call the aqueous dispersion of rubber particles latex, and the aqueous dispersion of resin particles emulsion. Products made from latex are called latex products, such as sponges, gloves, toys, rubber hoses, etc.
It is believed that many friends are not very familiar with polyurethane rubber sound insulation and shock absorption pads. This kind of decoration material is mostly used in public places with strong noise to meet the overall environment of public places and consumers' requirements for noise. In order to help friends better understand the product of polyurethane rubber sound insulation and shock absorption pads, we will introduce the characteristics and uses of polyurethane rubber sound insulation and shock absorption pads in detail. Interested friends, let's get to know!
Policy advantages of recycling rubber: developing circular economy and comprehensive utilization of renewable resources are the theme of social development today. The recycling of waste rubber has been highly valued by our country, and has been put on the agenda, which is encouraged by the state; Turn waste into treasure, turn harm into benefit, purify the environment, and establish a conservation oriented society. The Eleventh Five Year Plan for National Economic and Social Development, Part VI: Building a Resource conserving and Environment friendly Society. Chapter 22: "Developing circular economy", Section 5: "Strengthening the comprehensive utilization of resources and promoting the recycling of waste paper, waste metals, waste tires and waste electronic products." Part III, Article 35, "Production of powder, reclaimed rubber, liquid asphalt, tires, carbon ink, steel wire, waterproof materials, rubber seals, and logging products from waste rubber such as waste tires". Article 40 "Refurbishment and comprehensive utilization products of waste tires" enjoy preferential policies for comprehensive utilization of resources according to regulations.
Resource advantage of recycled rubber: With the development of rubber industry and automobile industry, a large number of waste tires, rubber products and other leftovers are increasing. According to statistics, only the scrap volume of tires in China is no less than 1.5 million tons every year, increasing at a rate of 10% every year, while the recent recovery rate is only 30%. Because the waste rubber can not be comprehensively utilized, most of it becomes industrial waste, which not only wastes a lot of available resources, but also causes black pollution, seriously affecting the living environment of human beings. China's annual rubber consumption ranks first in the world. At the same time, China is also a country with serious shortage of rubber resources. It imports rubber every year, accounting for 60% of the total consumption, and has no fundamental way to get rid of the status quo in a short time.
Generally speaking, recycled rubber additives can be classified into the following categories according to their functions and properties, such as vulcanizing agents, accelerators, active agents, reinforcing fillers, plasticizers, antioxidants, colorants, latex additives and additives for other purposes.
The main categories of recycled rubber additives and rubber additives are: 1. Vulcanizing agent (cross-linking agent), accelerator, activator and anti coking agent; 2. Antioxidants, anti ozone agents, anti flex cracking agents, light stabilizers, UV absorbers, harmful metal inhibitors, physical antioxidants, anti termite agents, anti mold agents, etc; 3. Including carbon black, white carbon black, metal oxide, inorganic salt, resin, etc; 4. Adhesives and adhesives for meta methylcellulose system and cobalt salt system; 5. Process operation aids include plastisol, solubilizer, plasticizer, softener, homogenizer, lubricant, dispersant, viscosifier, isolating agent, release agent, etc; 6. Colorants, foaming agents, defoamers, thickeners, creaming agents, wetting agents, emulsifiers, stabilizers, coagulants, thermosensitive agents, anti webbing agents, preservatives, preservatives, flame retardants, antistatic agents and aromatics.
