Problems solved by technology

Generally, high-pressure fireproof decorative laminates with a thickness of 0.7-1.5mm are single-sided decorations and need to be pasted on medium-density fiberboards, particle boards, woodworking boards and other substrates, while high-pressure fireproof decorative laminates with a thickness of 1.8-4.5mm are mostly It is double-sided decoration and can be used independently; however, the high-pressure fireproof decorative laminate is directly used for ordinary home improvement doors, the thickness is generally 38-42mm, the quality of the font is too large, the fireproof and sound insulation effects are poor, the hardness is high, it is not easy to saw and The edge is prone to defects such as edge collapse, and the price is also high

preparation example Construction

[0063] The preparation raw material ratio of the melamine-formaldehyde resin used in the preparation process of the impregnated surface paper for bonding is: the molar ratio of melamine and formaldehyde is 1:1.65, the quality of caprolactam is 13.5% of the quality of melamine, the quality of diethylene glycol 18% of the quality of melamine, the quality of sucrose is 1.5% of the quality of melamine, and the quality of thiourea is 2.2% of the quality of melamine; the preparation method of this melamine formaldehyde resin comprises the following steps: 1. adding metered formaldehyde in the reactor, Add water to adjust its mass concentration to 30%, then adjust the pH value of the solution to 9.2 to 9.5 with a 30% sodium hydroxide aqueous solution, start heating, and after the temperature is raised from room temperature to 40°C, add the measured Melamine, thiourea and sucrose, and the solution becomes clear when the temperature continues to rise to 70°C; ②After the solution becomes...

Embodiment 1

[0069] A kind of wooden substrate high-pressure decorative door panel according to the present invention, such as figure 2 As shown, the decorative door panel includes a substrate layer 3, a buffer layer 4 disposed on the substrate layer 3, a decorative layer 5 disposed on the buffer layer 4, and a wear-resistant protective layer 6 disposed on the decorative layer 5; A layer of impregnated surface paper layer for bonding is added between the substrate layer 3 and the buffer layer 4;

[0070] Such as figure 1 As shown, the substrate layer 3 includes at least two layers of wood substrate ply 1 (thickness of the wood substrate layer is 0.2-0.5mm) after flame retardant treatment, and the wood substrate layer 1 after flame retardant treatment An impregnated surface paper layer 2 for bonding is provided between the layers (that is, a layer of impregnated surface paper layer for bonding is provided between every two layers of wood substrate layers that have undergone flame-retardan...

Embodiment 2

[0079] The decorative layer of this embodiment is pressed with a hemp surface treatment and a louver-shaped mold.

[0080] A method for preparing a high-pressure decorative door panel with a wooden base material, comprising the following steps:

[0081] (1) Preparation of substrate layer

[0082] a.: Preparation of flame retardant liquid: uniformly mix ammonium polyphosphate, ammonium dihydrogen phosphate, and diammonium hydrogen phosphate according to the mass ratio of 1:1:1 to obtain a mixture, and then according to the mass ratio of the mixture to water as 1: 3, mixed evenly, heated to 40°C and stirred evenly, and the flame retardant liquid was prepared;

[0083] b. Flame retardant treatment of wood substrates: dry Chinese fir veneer in a wood drying room at 60-80°C until the moisture content is below 6%, then enter the pressure impregnation tank equipped with the fire retardant solution prepared in step a, add Pressurize to 0.4-0.48MPa, pressurize for 40 minutes and then...

Abstract

The invention discloses a high-pressure decorative door sheet comprising wood base materials and a preparation method of the door sheet. The door sheet comprises base plate layers, buffer layers, decorative layers and wear-resistant protective layers which are sequentially arranged from bottom to top, wherein the base plate layer comprises at least two wood base material layers and impregnated surface paper layers for bonding are arranged between the wood base material layers. The plate layers are sequentially stacked in an intermittent hot press in the order of one wear-resistant protection layer, one decorative layer, one buffer layer, one impregnated surface paper layer for bonding, one base plate layer, a polypropylene isolating membrane, the other base plate layer, the other impregnated surface paper layer for bonding, the other buffer layer, the other decorative layer and the other wear-resistant protection layer and then subjected to high-temperature and high-pressure one-time hot press molding. The high-pressure decorative door sheet comprising the wood base materials is flame-retardant, fireproof, wear-resistant, scratch-resistant, waterproof, damp-proof, impact-resistant, fouling-resistant and scrape-resistant, the decorative layers and the base materials are subjected to one-time hot press molding and can be used without pasting, decorative surface layers cannot peel off and mildew, the surface is easy to clean, the formaldehyde release amount and TVOC release amount are low, and no heavy metals are contained.

Description

technical field [0001] The invention belongs to the technical field of decorative door panels, and relates to a one-time molding high-pressure decorative door panel of a wooden base material and a preparation method thereof; in particular, it relates to a one-time molding high-pressure flame retardant with rotary-cut veneer or technical veneer applied with a flame retardant as the base material A door panel product for decorating interior and exterior doors and its production method. technical background [0002] At present, my country's interior doors mainly include solid wood interior doors, solid wood composite doors, sandwich molded hollow doors, steel-wood composite doors, etc. The solid wood interior doors are made of natural logs as a whole or spliced ​​with paint or paint for surface finishing. The solid wood composite door is made of hardwood frame, the door core is filled with spliced ​​wood or laminated wood, a piece of MDF is used on both sides, and the surface i...
