Tire reclaimed rubber is made of waste tires through physical and chemical processes such as cleaning, crushing, desulfurization, etc., with low cost and good processing performance, retaining most of the properties of the original rubber, and applying tire reclaimed rubber to the preparation of adhesives, which can not only improve the performance of adhesives, but also effectively reduce production costs and realize the reuse of resources. Today, I will share with you the application skills and formula optimization points of tire reclaimed rubber in the preparation of adhesives.
As a substance that can join two or more materials together, adhesives have a wide range of applications in many fields such as construction, automotive, and electronics. Tire reclaimed rubber is widely used in the preparation of adhesives because of its good adhesive performance and aging resistance. In actual production, tire reclaimed rubber 2SLYY1110 can be used in combination with natural rubber, styrene-butadiene rubber, etc. to prepare adhesives; The adhesive using tire reclaimed rubber is not only low cost, but also has good heat, oil and chemical resistance.
When designing a tire reclaimed adhesive formulation, there are many factors to consider, including the compatibility of reclaimed rubber with other additives, the adhesive's bond strength, temperature resistance, and cost-effectiveness.
Tire reclaimed rubber and natural rubber are used together to prepare a general black adhesive formula reference: 100 parts of natural rubber, 100 parts of tire reclaimed rubber, 50 parts of benzofuran resin, 50 parts of white powder, and 1.5 parts of antioxidant.
Tire reclaimed rubber and natural rubber are used together to prepare a general black adhesive with good heat resistance.
100 parts of natural rubber, 100 parts of tire reclaimed rubber, 60 parts of zinc resinate, 50 parts of clay, 1.5 parts of antioxidant, 10 parts of polyisocyanate.
When preparing adhesives from tire reclaimed rubber, the wood rosin derivative tackifier used must be of high acid value in order to accelerate the diffusion and dissolution of rubber; The use of 50 parts of wood rosin or zinc resin acid acid instead of oxadene resin to increase the acid value is helpful for the dissolution of reclaimed rubber; To improve the heat resistance of the adhesive, an appropriate amount of heat resistance additives such as silicate or magnesium oxide can be added.
Tire reclaimed rubber has important application value in the preparation of adhesives, and through reasonable formula design and performance optimization, adhesive products with excellent performance and high cost effectiveness can be prepared. This not only helps to improve the resource utilization rate of the rubber industry, but also an important way to promote the green development of the rubber industry; In the future, Xiaobian will continue to share with you the specific application of tire reclaimed rubber in adhesives.
