Problems solved by technology

Although the epoxy resin system has the advantages of high bonding strength, corrosion resistance, and long operating time, it has disadvantages such as low tolerance to temperature changes, poor toughness, and poor weather resistance. Pulverization, cracking and other phenomena will begin to appear
[0004] However, the existing polyurethane potting adhesives with high adhesive strength on the market have short operating time and poor high and low temperature resistance and cannot meet the requirements of use; while polyurethane potting adhesives with long operating time and good high and low temperature resistance have low adhesive strength and poor performance. Disadvantages such as high viscosity and high cost

Abstract

A pouring sealant for wind-driven generator cladding protection comprises a component A and a component B, wherein the mass ratio of the component A to the component B is 100:30; the component A comprises the following raw materials in parts by mass: 45-55 parts of polyol, 35-38 parts of calcium powder, 4-5 parts of a water removing agent, 5-10 parts of titanium dioxide, 0.5-1 part of a defoamingagent, 0.3-0.5 part of an adhesion promoter and 0.2-0.5 part of a wetting and dispersing agent; the component B comprises the following raw materials in parts by mass: 75 parts of carbodiimide modified MDI-50 and 25 parts of polymerized MDI. The pouring sealant is solvent-free, environmentally friendly and low in viscosity, can be cured at room temperature, and has the advantages of low cost, highadhesive strength, long operating time, good weather resistance, excellent high and low temperature resistance, namely no cracking after 120 cycles at -40-110 DEG C according to the frequency of 1 cycle per hour, capability of being used in a relatively wide temperature range, and the like.

Description

technical field [0001] The invention belongs to the technical field of polyurethane adhesives, and in particular relates to a potting adhesive used for coating protection of wind power generators and a preparation method thereof. Background technique [0002] With the development of economy and technology, environmental protection issues have become more and more important. Among them, wind power generation is currently one of the most environmentally friendly and energy-saving power generation methods. Therefore, it is urgent to develop a resin to protect it by potting to prolong its service life. [0003] At present, the resins used for potting of wind turbines mainly include epoxy resin and polyurethane. Although the epoxy resin system has the advantages of high bonding strength, corrosion resistance, and long operating time, it has disadvantages such as low tolerance to temperature changes, poor toughness, and poor weather resistance. It will begin to appear chalking, ...
