Problems solved by technology

However, its price is relatively high, as high as 35,000 to 45,000 yuan per ton, which greatly increases the application cost of domestic tire and rubber industries. At present, there is no mature and low-cost large-scale raw material production technology in China. The development of the industry has brought many restrictions. At present, the existing tackifying resins in the domestic market have poor adhesion, poor moisture resistance and high temperature resistance, so the rubber prepared by using it has the disadvantages of easy breakage and poor strength.

Abstract

The invention discloses a novel tackifying resin material for a tire and a synthesizing method, and relates to the technical field of synthesis of chemical raw materials. The novel tackifying resin material for the tire and synthetic raw materials comprise tert-butyl phenol, phenyl dimethyl ethanolamine, tetramethylammonium and methylbenzene. The substituent group of the novel tackifying resin material has a certain branching degree. Compared to rubber molecules, the novel tackifying resin material has the advantages that the compatibility is excellent, the novel tackifying resin material is easy to disperse in a sizing material, the rubber bonding performance is good, the initial bonding performance is improved, the bonding holding period is prolonged, the tackifying effect is remarkable, the preparation process is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of synthesis of chemical raw materials, in particular to a new tackifying resin material for tires and a synthesis method. Background technique [0002] There is an increasing need in the tire industry for improved rubber adhesion. Multiple layers of rubber-coated fabric are usually layered on top of each other, followed by components such as cushion, pads, and tread to build a tire. The layers of components must have sufficient surface tack to firmly bond to each other and maintain the desired relative position of the parts prior to vulcanization. Lack of adhesion makes build handling difficult with creep and displacement. Tackiness of the uncured vulcanized rubber compound is therefore always one of the most important properties required for building tires. In the tire industry, tackifiers are commonly used to provide build tack to rubber compounds. Unlike natural rubber, synthetic rubber does not have ...
