Problems solved by technology

Since the urea-formaldehyde resin is easy to hydrolyze and pyrolyze after curing, the high-pressure decorative board made of urea-formaldehyde resin-impregnated recycled paper as the core paper of the high-pressure decorative board has low tensile strength, and the humidity or temperature changes greatly after being combined with the substrate. It is easy to crack when it is used, and it is easy to break when it needs to open holes, drill holes, etc. during use

Embodiment 1

[0039] Preparation process of micro (nano) cellulose reinforcing agent

[0040] The conventional preparation method of the micro (nano) nano cellulose reinforcing agent adopted in the following examples of the present invention is as follows:

[0041] The wood pulp fiber paddles are added to the reaction vessel containing a sulfuric acid solution with a mass fraction of 30%, the mass ratio of the wood pulp fiber paddles to sulfuric acid is 1:10, heated and stirred at 60-70°C, fully hydrolyzed for 4-6 Add it to a high-speed homogenizer for about 6 hours to homogenize for about 6 hours, and obtain a milky white suspension that is a micro (nano) nanometer cellulose reinforcing agent for use.

Embodiment 2

[0043] Preparation process of reinforced melamine modified urea-formaldehyde resin

[0044] The preparation method that the present invention adopts is as follows:

[0045] Among them, the molar ratio of urea to formaldehyde used in the melamine-modified urea-formaldehyde resin is 1:1.90, the amount of melamine added is 10% of the amount of formaldehyde, and the amount of polyvinyl alcohol added is 0.2% of the total resin.

[0046] (1) First, add a metered amount of formaldehyde into the reaction kettle, add a micro (nano) cellulose reinforcing agent of 3 to 10% of the total amount of the resin for stirring, and adjust the concentration of the formaldehyde solution with 30% by mass of sodium hydroxide. When the pH reaches 9.0, start to heat up, and add melamine, polyvinyl alcohol and primary urea with 75% of the total amount of urea.

[0047] (2) Heat up to 85-88°C in 30 minutes, keep warm for 35 minutes, then add glacial acetic acid catalyst to adjust the pH value to 6.8, ...

Embodiment 3

[0050] Preparation process of reinforced melamine-formaldehyde resin for impregnating decorative paper

[0051] Production method of the present invention is as follows:

[0052] Among them, the molar ratio of melamine to formaldehyde in the melamine formaldehyde resin is 1:3.0;

[0053] (1) Add measured formaldehyde into the reaction kettle, add water to adjust the concentration to 30%, adjust the pH value to 9.2-9.5 with liquid caustic soda, and raise the temperature to 40°C.

[0054] (2) Add measured melamine into the reaction kettle, and the solution becomes clear when the temperature continues to rise to 70°C.

[0055] (3) Continue to heat up to 90-94°C, and after about 40 minutes of heat preservation, start to measure the water insolubility in 20°C water, measure the water-soluble ratio after the fogging point, and add 6% of the total mass of the resin when the glue:water ratio reaches 1:5 Ammonium dihydrogen phosphate and sodium pyrophosphate composite flame retarda...

Abstract

The invention discloses a production method of a high-strength high-pressure decorating plate. Firstly various needed strengthening thermosetting resins are prepared, kraft paper is socked in the strengthening thermosetting resins for gluing, and a soaking base plate blank is obtained after soaking and drying; monochrome paper or printing paper is soaked in the prepared strengthening thermosetting resins for gluing, and pre-socking decorative paper is obtained after soaking and drying; or metal drawbench aluminum foil with the pre-gluing back serves as the decorative paper; the wood pulp kraft paper is soaked in the prepared strengthening thermosetting resins for gluing, and pre-soaking buffer paper is obtained after soaking and drying; the soaking base plate blank, the pre-soaking decorative paper and the pre-soaking buffer paper are cut, paved according to requirements of prepared decorative plates, filled in a hot press for pressing, cooling, releasing, disassembling and plate discharging after paving, and treated to obtain the high-strength high-pressure decorating plate product. By means of the technical scheme, the production method can produce the high-strength high-pressure decorating plate which is fire-resistant, water-tolerant, moisture-resistant, impact-resistant, pollution-resistant, attractive and durable.

Description

technical field [0001] The invention relates to a production method of a decorative board, which belongs to the technical field of building material preparation technology, in particular to a production method of a high-strength and high-pressure decorative board. Background technique [0002] At present, my country's interior decoration materials mainly include paints, coatings, soft decoration materials wallpaper, wall coverings and decorative panels. Most paints and coatings contain volatile organic pollutants, which will cause a certain degree of potential harm to the use or the health of the occupants. Wallpapers, wall coverings, etc. have the disadvantages of being not waterproof, not moisture-proof, easy to fall off when the humidity is high, and easy to mold. Most of the glue used for pasting is a benzene solution of rubber adhesives. Most of the decorative panels are made of wood or wood derivatives, which are pasted on the substrate after being painted. [0003] ...
