Embodiment Construction
[0007] Below in conjunction with embodiment, the specific embodiment provided according to the present invention is described in detail as follows:
[0008] First, the adhesive, inorganic powder and non-woven fabric are mixed uniformly at 1:1:1 to produce a polymer sheet for use, and then the polyisocyanate and combined polyether are foamed into a polyurethane sheet by a polyurethane production line, and the polymer sheet is Composite to both sides of the polyurethane board to produce a polyurethane composite board.
[0009] The amount of polyisocyanate, combined polyether and foaming agent is 150:100:20 in parts by weight.

The invention discloses a production method of a rigid-foam polyurethane composite plate. According to the production method, a layer of polymer sheet is arranged on each of two sides of rigid-foam polyurethane, non-woven fabrics are arranged in the polymer sheets. The production method comprises the following steps of: producing the polymer sheets by using adhesive, inorganic powder and the non-woven fabrics; foaming polyisocyanate and combined polyether to produce a polyurethane plate by using a polyurethane production line and compositing the polymer sheets to the two sides of the polyurethane plate at the same time, thus obtaining the polyurethane composite plate. When used, the rigid-foam polyurethane composite plates are cut according to required size firstly, and then the cut rigid-foam polyurethane composite plates are spliced and adhered to walls, thus obtaining seamless integrated heat-insulating walls.
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. 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 complicated, continuous production cannot be realized, and the production cost is relatively high. Contents of the invention [0003] The invention provides a polyurethane composite board production process. It is provided with a layer of polymer sheets on both sides of rigid polyurethane foam, and non-woven fabrics are arranged inside the sheets; The cloth is mixed evenly to produce a polymer sheet, and then the polyisocyanate and combined polyether are foamed into a polyurethane sheet with a polyurethane ...
