Embodiment 1

[0028] Slurry preparation: under normal temperature and pressure, weigh 10 parts of water-based polyurethane resin, 50 parts of aluminum hydroxide, 0.5 parts of phosphorus-based flame retardant, and 39.5 parts of deionized water, and stir thoroughly, wherein the dispersion speed is 300-1200r / min, Disperse for 10-60 minutes until the resin slurry content reaches 20%.

[0029] Preparation of core layer: glass fiber thin mat weight 40g / m 2 , impregnated with water-based polyurethane resin slurry and then dried in an oven to obtain a prepreg core layer.

[0030] Hot press molding: Lay wear-resistant layer, decorative layer, five prepreg core layers, and balance layer sequentially from bottom to top, and carry out hot press compounding. The molding temperature is 130°C, the molding time is 20min, and the molding pressure is 10MPa. Afterwards, it is cut to obtain the finished product, and the combustion grade of the product reaches Class A.

Embodiment 2

[0032] The difference between this embodiment and embodiment 1 is: glass fiber felt grammage 80g / m 2 , the content of resin slurry is 40%, the molding time is 15min, and three prepreg core layers are used during hot pressing to obtain a product with a combustion grade of A grade.

Embodiment 3

[0034] The difference between this embodiment and embodiment 1 is: glass fiber felt grammage 50g / m 2 , impregnated with water-based epoxy resin slurry, the content of resin slurry is 70%, the molding temperature is 140°C, and the molding time is 25min, so as to obtain a product whose combustion level reaches Class A.

Abstract

The invention discloses a water-based formaldehyde-free fireproof antibacterial special functional board, wherein the water-based formaldehyde-free fireproof antibacterial special functional board sequentially comprises a wear-resistant layer, a decorative layer, a core layer and a balance layer from top to bottom, and the core layer is prepared by dipping a glass fiber mat in water-based resin slurry. Compared with the prior art, the characteristics of the glass fiber and the resin are organically combined, and the glass fiber reinforced plastic has the advantages of being good in fire resistance and water resistance, high in strength, mildew-proof, antibacterial, good in heat insulation and sound insulation and the like. Various decorations can be made on the surface, and different sizes and patterns such as highlight, matte and wood grain effects can be customized according to customer requirements. The provided plate is good in size stability and high in tensile strength, impact strength and bending strength, and can be widely applied to the field of home furnishing, decoration of public places and the like.

Description

technical field [0001] The invention belongs to the field of construction and relates to a decorative material, in particular to a water-based formaldehyde-free fireproof and antibacterial special functional plate and a preparation method thereof. Background technique [0002] Existing decorative boards are mostly made of wood pulp paper impregnated with thermosetting resin and then pressed under high temperature and high pressure. This type of traditional decorative board has disadvantages such as poor fire resistance, no antibacterial, no mildew proof, poor environmental protection, no waterproof, and poor mechanical properties. The thermosetting resin used in decorative panels on the market is the traditional "trialdehyde resin", which has a high formaldehyde emission and is harmful to human health. Moreover, urea-formaldehyde resin and phenolic resin contain more volatile organic compounds. It has a strong taste and endangers the health of workers. Most of the resin sol...
