Description

technical field [0001] The invention relates to a treatment agent, in particular to a surface treatment agent for thermoplastic elastomers. Background technique [0002] The general name of thermoplastic elastomer is TPE, which is also divided into TPU is thermoplastic polyurethane elastomer, TPV is vulcanized thermoplastic elastomer, TPR, etc. TPR is widely used in shoe sole materials in China. According to relevant data, the consumption of thermoplastic elastomer (TPE) in the world will be close to 2.2 million tons in 2006, and the total output value will exceed 11 billion US dollars. The world consumption will maintain an average annual growth rate of 6.4 parts between 2001 and 2006. The high-speed growth will drive all industries For the use of TPE in various industries, my country is a distribution center for footwear production, and the demand for TPR, a shoe sole material, is increasing day by day. The existing TPE treatment agent usually uses SBS (styrene-butadiene t...
