Embodiment Construction
[0009] Below in conjunction with embodiment, the specific embodiment provided according to the present invention is described in detail as follows:
[0010] The required components of the present invention:
[0011]
[0012] First, the adhesive, inorganic powder and non-woven fabric are evenly mixed to produce a polymer sheet for use, and then the polyisocyanate and combined polyether are foamed into a polyurethane sheet with a polyurethane production line, and the polymer sheet is compounded on both sides of the polyurethane sheet. Polyurethane composite panels are produced. Finally, spray the fireproof nano-coating on the surface of the polyurethane plate, and the spraying thickness is 5-20 μm. Naturally air-dried to obtain a polyurethane composite board coated with a fireproof nano-coating.

Abstract
The invention discloses a production method of a polyurethane composite plate with a fireproof coating. Two surfaces of polyurethane rigid foam are both provided with a polymer sheet, nonwoven fabrics are filled in the polymer sheets, and a fireproof nano coating is painted on the surface of the polyurethane composite plate composed of polyurethane and polymer sheets. The production method comprises the following steps: preparing polymer sheets from an adhesive, inorganic powder, and nonwoven fabrics, foaming polyisocyanate and combined polyether in a polyurethane production line to produce a polyurethane plate, at the same time, compounding polymer sheets to two surfaces of the polyurethane plate so as to produce a polyurethane composite plate, finally, spraying a fireproof nano paint onto the surface of the polyurethane composite plate, and naturally drying to obtain a polyurethane composite plate with a fireproof coating.
Description
technical field [0001] The invention relates to the field of building material processing, in particular to a method for producing a polyurethane composite board with a fireproof coating. Background technique [0002] Polyurethane composite board is a commonly used building material in the market. Because of its good adhesiveness, it is often used to bond with various metal materials to form a composite board, which is used for the insulation layer of houses. However, the production process is complex, continuous production cannot be realized, and the production cost is relatively high. At the same time, the polyurethane composite board also has the defect that it is easy to burn in case of fire. Contents of the invention [0003] The invention provides a polyurethane composite board production process with a fireproof coating, which is to provide a layer of polymer sheet on both sides of the rigid polyurethane foam, and a non-woven fabric is arranged in the sheet; The su...
