Abstract

The invention relates to the field of rubber industry, in particular to an environment-friendly bonding accelerator as well as a preparation method and application thereof. The invention discloses the preparation method of the environment-friendly bonding accelerator. The preparation method at least comprises the following steps of (1) material preparation: adding resorcinol, phenol, paraformaldehyde, formaldehyde and modifying agents into a reaction kettle according to a certain proportion ratio; (2) reaction: performing reaction on the mixed materials in the step (1) for 1 to 8h at 80 to 120 DEG C; performing temperature-rise dewatering for 3 to 8h at normal pressure; then, performing reduced pressure dewatering to 150 to 180 DEG C to obtain the environment-friendly bonding accelerator.

Description

technical field [0001] The invention relates to the field of rubber industry, in particular to an environment-friendly adhesion promoter and its preparation method and application. Background technique [0002] With the rise of the global low-carbon economy, "green production" has become one of the important strategic guidelines for the sustainable development of my country's rubber industry. Enlarging the industrial structure and vigorously developing clean production processes are the foundation of "green natural rubber production"; adjusting products The key to future competition is to strengthen the environmental protection of products and replace toxic and harmful products with green products. For the rubber additives industry, the development of high-performance, non-toxic, and non-polluting accelerators has become the most important research direction for industry technicians. [0003] At present, it is necessary to add resorcinol as an adhesion promoter in the bondin...
