Abstract

The invention discloses a high-temperature resistant and highly-condensed type waterproof seal puddle. The seal puddle is characterized by comprising the following raw materials in parts by weight: 30 to 45 parts of butadiene rubber, 30 to 45 parts of polyisobutene, 5 to 10 parts of carbon black, 0.5 to 1 parts of ebonite, 5 to 10 parts of nano calcium carbonate, 5 to 10 parts of superfine talcum powder, 0.3 to 1 part of antioxidant 1010, and 0.3 to 1 parts of anti-aging agent RD. The high-temperature resistant and highly-condensed type waterproof seal puddle has the advantages that the component proportion in the prescription is optimized, and the nano calcium carbonate is prepared, thus the puddle cannot overflow, flow and move at high temperature of 130 to 150 DEG C or under the external force of the type mentioned above, and has higher resistance to high temperature and high coagulative power.

Description

Technical field [0001] The present invention belongs to the field of rubber sealing rubber, and especially refers to a high temperature resistant, high cohesion waterproof sealing cement.It is used for waterproof, insulation, and sealing for electric power, communication, oil, construction, mining and other fields. Background technique [0002] Traditional waterproof sealing cement is under the action of high temperatures above 70 degrees and certain external forces (such as wrapped on cables, joint cables, or pipeline connections, external PVC tape or other materials wraps).Waterproof sealing performance. Invention content [0003] The purpose of the present invention is to overcome the above deficiencies, providing a high -temperature, high -condensed waterproof sealing cement. [0004] The present invention is achieved through the following technical solutions: a high temperature resistance, high cohesion waterproof sealing cement, including the following weight raw materials...
