Macromolecular moistureproof blocking agent

Abstract

The invention discloses a macromolecular moistureproof blocking agent. The moistureproof blocking agent is a double-liquid product prepared from two components of a main agent A and an auxiliary agentB, the ratio in parts by weight of the main agent A to the auxiliary agent B is 1 to 1, the component A is prepared from the elements in parts by weight: 60-70 parts of macromolecular polyether, 3.5-5 parts of chain extender, 0.7-1.0 part of self-made catalyst, 0.7-0.9 part of organic silicon surface active agent, 0-0.2 part of foaming agent, 10-15 parts of TCPP, 4-6 parts of flame retarding agent, 1-3 parts of anti-static agent, 4-6 parts of rutile titanium dioxide, 4-6 parts of aluminum hydroxide, 4-6 parts of light calcium carbonate, 2-4 parts of light magnesium carbonate, 0.01-0.05 part of anti-UV agent and 0.1-0.2 part of organic tin. The component B is various kinds of isocyanate, in particular DG-1521 material or PAPI. The initial viscosity of the reactive mixture of the macromolecular moistureproof blocking agent is very low, the macromolecular moistureproof blocking agent can be convenient to permeate and level, meanwhile, time is adjustable, the hardening time is short, theblocking agent is elastic, has the high binding strength, is flame retarding and antistatic, can block and fill under the existence of water and waterproof environment, and is applicable to various kinds of severe environments.

Description

technical field [0001] The invention relates to a moisture-proof sealing agent, in particular to a polymer moisture-proof sealing agent. Background technique [0002] Adhesive reinforcement plugging filling materials are widely used in explosion-proof fuel tanks in aerospace and other industries, plugging and sealing of underground power systems in coal mines, and moisture-proof sealing. Sealing agents are also widely used for waterproofing, moisture-proofing, insect-proofing and rodent-proofing in floors and other places. Traditional sealing agents include fireproof cement and inorganic sealing materials. This kind of anti-blocking agent has poor flame retardant and antistatic properties Low, insufficient toughness, inconvenient construction, high cost and other disadvantages, a polymer moisture-proof sealing agent is proposed. Contents of the invention [0003] The object of the present invention is to provide a polymer moisture-proof sealing agent, the initial viscosit...
