Insulating rubber pads with natural rubber as the main raw material are widely used in power distribution rooms, laboratories and other places; the price of natural rubber is high and the price fluctuates greatly, so more rubber reclaimed rubber is used in the production of rubber pads. The use of latex reclaimed rubber instead of natural rubber to produce insulating rubber pads has advantages that cannot be ignored in terms of cost, process and performance. Reasonable use of latex reclaimed rubber can produce more cost-effective insulating pads.
1. The advantages of using latex reclaimed rubber for insulating rubber pads
Compared with natural rubber, the price of reclaimed latex rubber is low. The replacement of natural rubber to produce insulating rubber pads can effectively reduce the cost of raw materials and improve the ability of rubber product manufacturers to control the cost of raw materials. From the processing performance point of view, reclaimed latex rubber has better fluidity and plasticity, and it is not easy to cause vulcanization inversion during vulcanization. It is used for rubber mat production with low power consumption and good vulcanization effect. From the perspective of the performance of the finished product, the finished product size of the insulating rubber pad added with latex reclaimed rubber is more stable and has better aging resistance.
2. Tips for using latex reclaimed rubber for insulating rubber pads
There are black insulating rubber pads and various colored insulating rubber pads on the market. The insulating rubber pad 2LLYY914 has higher requirements for electrical insulation and elasticity of rubber. When using latex reclaimed rubber to replace natural rubber to produce insulating rubber pads, rubber product manufacturers need to choose appropriate latex reclaimed rubber, reasonably determine the amount of latex reclaimed rubber, appropriately adjust rubber product formulas, and reduce more raw material costs while ensuring product quality.
(1) Selection of latex reclaimed rubber for rubber pads: When using latex reclaimed rubber to reduce the production cost of insulating rubber pads, it is necessary to select appropriate indicators of reclaimed rubber according to the physical properties of the insulating rubber pad, including tensile strength, elongation at break, and hardness , Abrasion resistance, etc.; white latex reclaimed rubber can produce white and color insulating rubber pads, or directly use red and green latex reclaimed rubber to produce red and green insulating rubber pads, and black latex reclaimed rubber is more cost-effective.
(2) Usage and dosage of reclaimed latex rubber in rubber pads: In actual production, natural reclaimed rubber can replace all natural rubber to produce insulating rubber pads, or use natural rubber together to produce products with higher performance. Insulating rubber pad processing companies generally determine the amount of latex reclaimed rubber blended by the mechanical strength requirements of the insulating rubber pad and the physical performance indicators of the reclaimed rubber. In theory, the higher the rubber content, the higher the rubber content can replace the more natural rubber.
(3) Formula of insulating rubber pad containing latex reclaimed rubber
When using reclaimed rubber to reduce the raw material cost of natural rubber insulating rubber pads, rubber product manufacturers can rationally adjust the type and amount of compounding agents in the formula to improve product performance, and increase the amount of reclaimed rubber to a certain extent, reducing more raw material costs. For example, when the hardness of the insulating rubber pad is high, the amount of high wear-resistant carbon black should be appropriately increased; by increasing the amount of sulfur to increase the cross-linking density of the vulcanized rubber, and then the strength of the rubber pad; appropriately increase or decrease sulfur, softeners, and anti-aging according to the change in the amount of reclaimed rubber Dosage, etc.
Reasonable use of reclaimed latex rubber in insulating rubber pads can achieve a win-win situation of quality and cost. Later, the editor will continue to discuss with you the production technology and formula design skills of insulating rubber pads containing latex reclaimed rubber.
