Embodiment 1 to 10

[0064] The solvent-free heat-insulating and anti-corrosion paint in the embodiment 1 to 10 of the present invention is realized by the following production process:

[0065] Component A: Use a high-speed disperser to mix the epoxy resin and the active diluent evenly. During the mixing process, add rheology agent, rutile titanium dioxide and airgel, and disperse at high speed to a maximum fineness of 60 microns; then add hollow glass microspheres, Stir well.

[0066] Component B: Add curing agent to the high-speed disperser, add rheology agent and rutile titanium dioxide during stirring, disperse at high speed to a maximum fineness of 60 microns, then add hollow glass microspheres, stir evenly, then add epoxy accelerator and Adhesion promoter, stir well.

[0067] Before use, component A and component B were mixed according to the weight ratio shown in Table 1 to prepare solvent-free heat-insulating and anti-corrosion coatings in various embodiments of the present invention.

Embodiment 1

[0068] The composition of the solvent-free thermal insulation and anticorrosion coatings provided in Examples 1 to 6 is shown in Table 2. If there is no corresponding component in Table 2, the component will not be added during the production process. The weight composition of Examples 7 to 10 is the same as that of Example 1.

Abstract

The invention provides a solventless thermal-insulation anticorrosive coating and an anticorrosive coating layer. The solventless thermal-insulation anticorrosive coating includes epoxy resin, an epoxy reactive diluent, a curing agent, an aerogel, and hollow glass microspheres. According to the solvent-free thermal-insulation anticorrosive coating provided by the invention, the epoxy resin, the reactive diluent, the curing agent, the aerogel and the hollow glass microspheres cooperate for use, so that the thermal insulation, compressive strength, corrosion resistance, durability and workability of the solvent-free thermal-insulation anticorrosive coating can be improved, and heat preservation, thermal insulation, low-temperature leakage protection, fire protection, corrosion resistance under a thermal-insulation layer and thermal shock protection on high-heat low-temperature steel surfaces can be provided to prevent heat loss and improve processing efficiency; and in addition, the coating has an extremely-low VOC content, can significantly improve construction efficiency, reduce construction time, and realize zero VOC emission, thereby ensuring that the coating conforms to extremely-strict environmental protection laws and regulations.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a solvent-free heat-insulating anti-corrosion coating and an anti-corrosion coating. Background technique [0002] In many refineries, it is normal procedure to isolate areas that operators may come into contact with above 60°C to prevent contact burns and skin scalds. Insulation is also often necessary at higher operating temperatures to prevent heat loss and improve processing efficiency. [0003] In general, the insulation materials used are mainly based on rock wool, cellular glass and calcium silicate. These materials have different water absorption rates, but all need to be wrapped with stainless steel or tied with special tape to fix the seal and prevent water from seeping into the gaps and reaching the steel surface. [0004] Unfortunately, in almost all cases, once installed, even an initial waterproof seal with proper mastic can be damaged by mishandli...
