A kind of high-strength fire-retardant decorative panel
Technical field:
The utility model relates to a kind of high-strength fire-retardant decorative panel, belongs to building and ornament materials.
Background technology:
Decorative panel is building finishing industry a kind of decorating and renovating material commonly used, almost all adopt decoration facial tissue and ox-hide base paper heat of immersion thermosetting resin (melamine resin, phenol formaldehyde resin, urea-formaldehyde resin) after the hot press moulding moulding, pattern is various, thickness is generally from 0.5-1.2mm, though having maximum problem is that used resin has certain refractoriness, but because of matrix is paper, do not reach reliable flame retardant effect, and discharge a large amount of toxic smogs during burning, require under the more and more higher situation at fire safety, the application of common decorative is restricted.And state's inner trim panels base paper mostly is regeneration kraft greatly, and intensity is lower, and especially transverse tensile strength is low, and the high or distortion as used stickup base material moisture content very easily causes plate face cracking, and influence is used.
Summary of the invention:
The purpose of this utility model is to solve the not high and low problem of tensile strength of fireproof performance that existing decorative panel exists, and a kind of high-strength fire-retardant decorative panel that a kind of surfacing is various, pattern is various, fireproof performance is good, tensile strength is high is provided.This plate oxygen index (OI) can reach more than 38, can not discharge poisonous asphyxiant gas, and tensile strength can reach 70MPa, water-fast, shock-resistant, surperficial anti-pollution of while, and dimensional stability is good.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-strength fire-retardant decorative panel of the utility model is the fireproof decoration plate of a kind of thickness at 0.8-1.2mm, it is made up of decorative layer, cushion coat, fireprotection layer, base layer, it is characterized in that: described centre at decorative layer and base layer is provided with cushion coat and fireprotection layer, described decorative layer adopts the facing paper that has flooded thermosetting resin to constitute, pattern is various, monochromatic paper and printing paper are arranged, and surfacing can be pitted skin, inferior light, high light or special-shaped pitted skin; Described cushion coat adopts the kraft that has flooded thermosetting resin to constitute, described fireprotection layer adopts the glass cloth formation of having flooded thermostable phenolic resin and having added the pure dissolubility phenolic resins of fire retardant, and described base layer adopts the kraft that has flooded thermosetting resin to constitute; Described fireprotection layer reaches difficult combustion grade standard through the synthetic integral body of high temperature (more than 130 ℃) high pressure (more than the gauge pressure 19Mpa) and decorative layer, cushion coat and base lamination.The utility model is widely used in office space, hotel, kitchen tools, high patience and the high place of fire protection requirement.
Beneficial effect:
The utility model surfacing is various, pattern is various, fireproof performance is good, tensile strength is high, this plate oxygen index (OI) can reach more than 38, can not discharge poisonous asphyxiant gas, and tensile strength can reach 70MPa, water-fast, shock-resistant, surperficial anti-pollution of while, dimensional stability is good.:
Description of drawings:
Fig. 1 is the structure chart of a kind of high-strength fire-retardant decorative panel of the utility model.
The specific embodiment:
As shown in the figure, a kind of high-strength fire-retardant decorative panel of the utility model is the fireproof decoration plate of a kind of thickness at 0.8-1.2mm, it is made up of decorative layer 1, cushion coat 2, fireprotection layer 3, base layer 4, it is characterized in that: described centre at decorative layer 1 and base layer 4 is provided with cushion coat 2 and fireprotection layer 3, described decorative layer 1 adopts the facing paper that has flooded thermosetting resin to constitute, pattern is various, and monochromatic paper and printing paper are arranged, and surfacing can be pitted skin, inferior light, high light or special-shaped pitted skin; Described cushion coat 2 adopts the kraft that has flooded thermosetting resin to constitute, described fireprotection layer 3 adopts the glass cloth formation of having flooded thermostable phenolic resin and having added the pure dissolubility phenolic resins of fire retardant, and described base layer 4 adopts the kraft that has flooded thermosetting resin to constitute; Described fireprotection layer 3 is pressed into an integral body through high temperature (more than 130 ℃) high pressure (more than the gauge pressure 19Mpa) and decorative layer 1, cushion coat 2 and base layer 4, reaches difficult combustion grade standard.
Among the embodiment of the present utility model, the thickness of cushion coat and fireprotection layer can be made other thickness according to the needs of product requirement.The pre-soaked resin of decorative layer can adopt melamine resin and cyanurotriamide modified urea resin, and the pre-soaked resin of cushion coat can adopt cyanurotriamide modified urea resin, phenol formaldehyde resin, Lauxite.The pre-soaked resin of base paper can adopt phenol formaldehyde resin, cyanurotriamide modified urea resin and Lauxite.The decorative panel surfacing can be various ways such as inferior light, Gao Guang, pitted skin, special-shaped pitted skin.
