Latex recycled rubber is a kind of recycled and environmentally friendly rubber products, which are made from waste latex products after recycling. In the rubber products industry, latex reclaimed rubber is more and more widely used. Many friends do not know how to use latex recycled rubber after purchasing it, or operate according to the method of mixing natural rubber, in fact, this is wrong.
First, latex reclaimed rubber mixed rubber formula
The mixing formula of latex reclaimed rubber is developed and adjusted by latex reclaimed rubber manufacturers according to product performance requirements and market demand, and under normal circumstances, latex reclaimed rubber manufacturers will provide standard formulas for customers to use. These formulations have been tested many times to have good stability and reliability, and customers can also choose the right formula for production according to their own needs. Some latex reclaimed rubber manufacturers can also provide customized compounding formulations according to the specific needs of customers. For example, according to the customer's product requirements and process conditions, adjust the composition ratio and additive type of latex reclaimed rubber and other rubber grades. This customized formulation can better meet the specific needs of customers and improve the performance and quality of the product.
The general latex reclaimed rubber compound formula provided by Hongyun recycled rubber: latex reclaimed rubber 30kg, TBBS accelerator 0.24kg, primary indirect zinc oxide 0.75kg, stearic acid 0.1kg, sulfur 0.35kg, vulcanization temperature 145 °C, vulcanization time 10-20 minutes
Second, the price of latex reclaimed rubber compound
The price of latex reclaimed compound is affected by several factors. The first is the cost of raw materials, including the procurement cost of waste latex, the cost of recycling treatment, the cost of auxiliary materials, etc.; Secondly, the recycling price of waste latex products will be affected by factors such as market supply and demand, recycling channels and so on; In addition, the cost of regeneration treatment is affected by factors such as equipment investment, energy consumption, and desulfurizer selection; Finally, the cost of auxiliary materials for mixing is basically not much different.
The production process also has a greater impact on the price of latex reclaimed rubber. Different latex regeneration production processes have an impact on product quality and cost. The use of advanced regeneration processing technology and equipment can improve production efficiency and reduce production costs, thereby affecting the price of latex reclaimed rubber. The fineness, taste, environmental grade, tensile strength, tear elongation, stability, etc. of latex reclaimed rubber and mixed rubber all have a greater impact on the price.
The price of latex reclaimed rubbermixed rubber finished products is related to color, strength, elongation, specific gravity, taste, environmental protection, etc., generally 8 MPa odorless black latex reclaimed rubber compound price 6-7 yuan / kg, 8 MPa light color or color odorless latex reclaimed rubber compound 8-11 yuan / kg.
Third, latex reclaimed rubber mixing process
The mixing method of latex reclaimed rubber is similar to traditional rubber, mainly including mixing equipment selection, mixing process and other links, compared with natural rubber, eliminating the process of plastic refining 1 stage and 2 stages, and there must be a process of parking to restore the degree of crosslinking.
The first is the selection of mixing equipment. The mixing equipment of latex reclaimed rubber can choose a mill, a mixer, etc. The open mill is suitable for small batch production and simple operation, but the mixing effect is relatively poor, the pollution is large, and the energy consumption is high; The mixer is suitable for mass production, the mixing effect is better, the pollution is small, but the equipment investment is high. It is necessary to select the appropriate mixing equipment according to the production scale and product performance requirements.
The second is the mixing process. The mixing process includes mixing temperature, mixing time, additive feeding sequence, etc. Reasonable control of the mixing process can improve the quality and stability of latex reclaimed rubber. Controlling the mixing temperature and time can make the dispersion and fluidity of latex reclaimed rubber better, and improve the processing performance of the product. The mixing temperature of latex reclaimed rubber is generally controlled below 90 °C, and the mixing time can generally be within 4-7 minutes according to feeding. High temperature and long-term mixing can easily lead to the aging of the compound, and the addition of antioxidants or anti-coking agents to the mixer can alleviate it. If there is no water cooling equipment or cooling equipment can not meet the demand in summer, the amount of superimposed grease plasticizer is the most common problem in summer.
In summary, it can be seen that latex reclaimed rubber manufacturers generally provide standard formulas for customers to use, and can also provide customized formulas according to the special needs of customers; The price of latex reclaimed rubber compound rubber is affected by many factors such as raw material cost, production process, performance requirements and so on; The mixing method of latex reclaimed rubber includes the selection of mixing equipment and the mixing process. Hongyun Reclaimed Rubber provides free latex reclaimed rubber mixing formula and vulcanization process guidance, and the mixing center can undertake the nearby compound rubber business. Through the reasonable selection of rubber mixing formula and mixing process, it is possible to produce latex reclaimed rubber products with stable quality and excellent performance.
