Problems solved by technology

The wooden fire doors made by this process are easy to crack, which affects the fire performance and aesthetics of wooden fire doors
The fireproof substrates used in the existing wooden fire doors are all flat wooden substrates, which cannot be made into complicated shapes.
The edge banding strips of the existing wooden fire doors are basically ordinary veneer without fireproof treatment, and the edge banding made of this common veneer reduces the fire performance of wooden fire doors

Abstract

A fireproof UV pre-coated paper sequentially comprises a first fireproof layer, a paper layer, a second fireproof layer and a fireproof UV paint layer from bottom to top, and the raw material of the first fireproof layer is the same as that of the second fireproof layer. The thickness of the paper layer is 25-50 filaments, and the air permeability of the paper layer is 200-230 [mu]m / Pa.s. The first fireproof layer and the second fireproof layer both comprise following raw materials in parts by weight: 10-20 parts of fireproof liquid and 90-100 parts of an aqueous paint. The fireproof liquid isprepared from the following raw materials in parts by weight: 1-3 parts of a fireproof flame retardant and 2-5 parts of deionized water. The aqueous paint is one of aqueous acrylic emulsion or aqueous polyurethane emulsion. The solid content of the aqueous acrylic emulsion is 38%-46%, and the solid content of the aqueous polyurethane emulsion is 35%-44%. The paper layer is soaked in the aqueous acrylic emulsion containing the fireproof liquid or the aqueous polyurethane emulsion containing the fireproof liquid, the first fireproof layer is formed on the lower surface of the paper layer, the second fireproof layer is formed on the upper surface of the paper layer, the paper layer has a primary fireproof performance, the second fireproof layer is coated with the fireproof UV paint, and thefireproof performance of the paper layer is further improved.

Description

technical field [0001] The invention belongs to the technical field of decoration, and in particular relates to a fireproof UV precoated paper and a manufacturing method thereof. Background technique [0002] Fire doors are one of the facilities for building fire separation. They are usually used on firewalls, entrances and exits of stairwells or openings of pipe wells, and play an important role in reducing fire losses. Existing wooden fire doors are generally manufactured by the following process. First, soak the wooden substrate in fireproof liquid, then dry the wooden substrate soaked in fireproof liquid, apply fireproof material after drying, and finally apply fireproof paint. The wooden fireproof door made by this process is easy to crack, which affects the fireproof performance and aesthetics of the wooden fireproof door. The fireproof substrates selected by existing wooden fire doors are all flat wooden substrates, which cannot be made into complicated shapes. The ...
