Abstract

The invention discloses a novel silane coupling agent and a preparation method thereof. The novel silane coupling agent comprises 45-65 percent of retinoid metal salts containing aromatic groups, 4-5 percent of white carbon black and 30-60 percent of silane coupling agent and can be prepared by mixing the retinoid metal salts containing aromatic groups with the white carbon black under the normal temperature condition, stirring for 5-15min at the rotation speed of 1000-1200rpm, uniformly adding the silane coupling agent and continuously stirring for 5-15min at the rotation speed of 1000-1200rpm. Compared with the prior art, the invention can effectively solve the transportation and the weighing of the silane coupling agent and is suitable for shallow and cored products. In addition, the novel silane coupling agent disclosed by the invention has the functions of reducing the consumption and resisting the curing reversion. The cost of users can be greatly saved.

Description

technical field [0001] The invention relates to a coupling agent, in particular to a silane coupling agent for rubber. Background technique [0002] Coupling agents refer to chemical substances that can improve the bonding force between inorganic reinforcing materials or fillers and polymer interfaces, and are often used as surface modifiers for inorganic powder materials. According to the chemical structure, the coupling agents mainly include silanes, titanates, phosphorus-containing compounds, amines and complexes. Among them, the silane coupling agent is the one with the most varieties and the largest dosage. However, most silane coupling agents have a problem, that is, silane coupling agents are generally transparent liquids, which will be hydrolyzed when in contact with water or moisture, which brings great inconvenience to their transportation and use. In order to solve this problem, various companies have proposed different improvement schemes. For example, for Si6...
