Abstract

The invention relates to a non-combustible rubber treating agent and application thereof.The treating agent is composed of a component A and a component B. The component A is prepared from 70%-85% of dichloromethane, 0-15% of acetone and 0-20% of N, N-dimethylformamide; the component B is trichloroisocyanuric acid; and the mass ratio of the component A to the component B is 100: (2-8). The non-combustible rubber treating agent provided by the invention cannot be ignited through an open fire ignition experiment, and according to the detection of GB / T3536-2008 measuring of Flicker Point and Ignition Point of Petroleum Products, the rubber treating agent has no flash point (no Ignition Point); and a conveyor belt rubber product synthesized from natural rubber, chloroprene rubber and butadiene styrene rubber treated by the rubber treating agent is bonded by using a polyurethane type adhesive, and the bonding strength of a damaged conveyor belt rubber matrix can be achieved. The adhesive is applied to the field of maintenance of heavy-load industrial conveying belts and the field of adhesion of rubber products.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a non-combustible rubber treatment agent. Background technique [0002] Rubber is a non-polar material with poor adhesion. The adhesives used for bonding rubber in the prior art mainly include instant dry adhesive, neoprene, polyurethane glue and solvent-based polyurethane. In the field of large-area rubber bonding and industrial conveyor belt maintenance, instant adhesives are rarely used; although neoprene-type adhesives are used more, but due to slow curing and low bonding strength, its bonding quality is critical for many industries. The situation is also difficult; polyurethane type adhesives are increasingly used in the field of heavy-duty conveyor belt maintenance due to their solidified blocks and high bonding strength. In the prior art, when using polyurethane adhesives to bond rubber, it is usually necessary to carry out "chemical modification tre...
