Problems solved by technology

[0005] However, for most veneer decorative papers made by impregnating melamine resin, in order to improve the bonding strength and storage period during the preparation process, the producers will increase the ratio of formaldehyde to urea and melamine, so that the decorative paper obtained by impregnating glue High content of free formaldehyde
The release cycle of formaldehyde in decorative paper and wood-based panels is long. Although the veneer decorative paper can better seal the release of formaldehyde inside the wood-based panel substrate, it will release formaldehyde and VOCs itself, and formaldehyde will still appear in the panel after veneering. The release amount is high or even exceeds the standard, which affects indoor air quality and people's health

Embodiment 1

[0033] The laminated decorative paper with flame retardant effect of this embodiment is prepared by the following method:

[0034] 1) Preparation of modified starch paste: add phosphate amphoteric starch into water to prepare a starch dispersion with a mass concentration of 1%, heat it in a water bath to 85°C for 30 minutes to fully gelatinize, and cool to obtain a modified starch paste;

[0035] According to the mass ratio of coniferous wood pulp to hardwood pulp at a ratio of 3:7, take the coniferous wood pulp and hardwood pulp to be beaten separately, mix and decompose, add titanium dioxide dispersion, retention aid, wet strength agent and modified starch The paste is evenly mixed so that the amount of titanium dioxide added is 20% of the absolute dry pulp mass, the amount of retention aid is 0.8% of the absolute dry pulp mass, the amount of wet strength agent is 1.2% of the absolute dry pulp mass, and the amount of modified starch is 1.0% of the mass of the absolute dry pulp, a...

Embodiment 2

[0041] The laminated decorative paper with flame retardant effect of this embodiment is prepared by the following method:

[0042] 1) Preparation of modified starch paste: add phosphate amphoteric starch to water to prepare a starch dispersion with a mass concentration of 1.2%, heat it in a water bath to 90°C for 15 minutes to fully gelatinize, and cool to obtain a modified starch paste;

[0043] According to the mass ratio of coniferous wood pulp and hardwood pulp of 4:6, take coniferous wood pulp and hardwood pulp to be beaten separately, mix and decompose, add titanium dioxide dispersion, retention aid, wet strength agent and modified starch The paste is evenly mixed so that the amount of titanium dioxide added is 22% of the absolute dry pulp mass, the amount of retention aid is 1.0% of the absolute dry pulp mass, the amount of wet strength agent is 0.8% of the absolute dry pulp mass, and the amount of modified starch is 1.2% of the mass of the absolute dry pulp, adjusted to neu...

Embodiment 3

[0049] The laminated decorative paper with flame retardant effect of this embodiment is prepared by the following method:

[0050] 1) Preparation of modified starch paste: add phosphate amphoteric starch to water to prepare a starch dispersion with a mass concentration of 1.5%, heat it in a water bath to 90°C for 25 minutes to fully gelatinize, and cool to obtain a modified starch paste;

[0051] According to the mass ratio of coniferous wood pulp and hardwood pulp as 3.5:6.5, take the coniferous wood pulp and hardwood pulp to be beaten separately, mix and decompose, add titanium dioxide dispersion, retention aid, wet strength agent and modified starch The paste is evenly mixed so that the amount of titanium dioxide added is 25% of the absolute dry pulp mass, the amount of retention aid is 1.2% of the absolute dry pulp mass, the amount of wet strength agent is 1.0% of the absolute dry pulp mass, and the amount of modified starch is 1.5% of the mass of the absolute dry pulp, adjuste...

Abstract

The invention relates to veneering decorative paper having a flame-retardant effect and a flame-retardant veneering artificial board using the same. The veneer decorative paper is prepared by the following method: 1) taking needle leaf wood pulp and broad leaf wood pulp, respectively beating, mixing and defibering, adding a titanium dioxide dispersion liquid, a retention aid, a wet strength agentand modified starch paste, to prepare original paper; 2) carrying out double-side coating on the obtained original paper with silica sol to obtain modified paper A; (3) carrying out impregnation treatment on the modified paper A with a borax solution to obtain modified paper B; and 4) carrying out double-side coating and gluing on the modified paper B with a soybean protein glue liquid with the gluing amount of 12-15 g/m<2>, and then carrying out press polishing with a press polishing machine. The obtained veneering decorative paper makes a flame-retardant agent added to the paper by using silica sol coating and borax solution impregnating, so the limit oxygen index of the decorative paper and the ignition time of the veneering artificial board are improved, and a good effect on preventingthe expansion and spreading of fire is achieved. The decorative paper does not contain formaldehyde, can greatly reduce the formaldehyde release amount of the veneering artificial board, and is suitable for promotion and use.

Description

Technical field [0001] The invention belongs to the technical field of artificial board veneer decorative paper, in particular to a veneer decorative paper with flame retardant effect, and also to a flame-retardant veneer artificial board using the decorative paper. Background technique [0002] Flame-retardant veneer wood-based panels are based on flame-retardant wood-based panels or ordinary wood-based panels, covered with flame-retardant veneer decorative paper on the surface, and are prepared by low-pressure short-cycle hot pressing technology with flame-retardant performance levels The veneer board has the advantages of rich pattern color change, low price, and certain flame retardant effect. It is widely used in living room table cabinet furniture, kitchen cabinets, decorative wall panels, hanging panels, ceilings, and partitions in public places. [0003] Since the main raw materials of veneer wood-based panels are wood products or wood fibers, which are extremely flammable ...
