Embodiment Construction

[0010] A rigid polyurethane foam insulation material with fireproof and anticorrosion function, 20-30 parts of modified high-chlorinated polyethylene is melted into a 30% solution under high-speed stirring, and 10-15 parts of acrylic resin and epoxy resin are mixed : Add 4-5 parts, add 1-2 parts of organic expansive soil under low-speed stirring, and stir for about ten minutes; then add 2-5 parts of melamine, 6-10 parts of pentaerythritol, 6-10 parts of zinc aluminate, 13 - 15 parts of ammonium polyphosphate, 2-6 parts of chlorinated paraffin, 2-6 parts of titanium dioxide, 4-8 parts of flame retardant, etc., after stirring for 30 minutes, send it to the grinder for grinding, and stop grinding after the detection fineness reaches 90μm; Add 1-2 parts of defoamer under stirring, and add all the remaining 10-15 parts of solvent and stir evenly. Apply the prepared fire-proof intermediate to the base material that has been sprayed with a penetrating primer on the rigid polyurethane...

Abstract

The invention is a rigid polyurethane foam insulation material with fireproof and anticorrosion function and its preparation method, which is composed of rigid polyurethane foam, penetrating primer, fireproof intermediate paint and anticorrosion sealing topcoat, and is characterized in that the surface of rigid polyurethane foam is sprayed A layer of penetrating primer, spray a layer of fireproof intermediate paint on top of the penetrating primer; finally spray a layer of anti-corrosion sealing topcoat on the dried substrate. The manufacturing process of the rigid polyurethane foam insulation material is as follows: spray a layer of penetration primer with a thickness of 30-40 μm on the polyurethane foam, and spray a fireproof intermediate paint with a thickness of 1-3 mm on the penetration primer; finally spray a layer of thickness 30-40μm anti-corrosion sealing topcoat. According to the polyurethane rigid foam fireproof and anticorrosion paint of the present invention, it has the properties of firm adhesion to the base layer, corrosion resistance, and can be sprayed and formed on any curved surface. The special paint has the advantages of thin coating, long flame resistance time, less smoke generation, and low toxicity.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a spray-formed rigid polyurethane foam SPF: Sprayed Polyurethane Foam thermal insulation layer used in the construction field, more specifically a rigid polyurethane foam thermal insulation material with fireproof and anticorrosion functions and its preparation method. Background technique [0002] Rigid polyurethane foam is a material with thermal insulation and certain waterproof functions. The foam has good thermal insulation and heat insulation functions, extremely low thermal conductivity, and is impermeable, non-hygroscopic, insulating, sound-absorbing, oil-resistant, and chemically resistant. , light weight, very suitable for various types of new buildings and existing roof waterproofing and heat preservation, so it is widely used in the heat preservation, heat insulation and waterproof of roofs, walls and floors of various industrial and civil buildings. [0003] Among th...
