Problems solved by technology

[0002] Existing melamine-formaldehyde resin impregnated products are mainly impregnated with ordinary decorative paper, and there are also a small number of products such as veneer and veneer impregnated with impregnated decorative paper. Since the main difference between veneer and decorative paper lies in its non-uniformity, the horizontal The tensile strength of grain is low, and it is easy to be damaged during dipping and veneering operations, and cracks are easy to occur on the surface after veneering, especially when the veneering temperature is high, the defects produced are more obvious; at the same time, the existing melamine formaldehyde resin impregnated products are generally Does not have antimicrobial properties
Therefore, the existing melamine formaldehyde resin impregnated paper and impregnated veneer products cannot meet the antibacterial requirements.

Abstract

The invention relates to antibacterial terpolycyantoamino-formaldehyde resin impregnated veneer which is characterized in that the veneer is prepared by steps as follows: synthesis of terpolycyantoamino-formaldehyde resin, preparation of a terpolycyantoamino-formaldehyde resin veneer impregnation adhesive, preparation of a antibacterial terpolycyantoamino-formaldehyde resin veneer impregnation adhesive, manufacturing of antibacterial impregnated veneer and the like. The prepared veneer can be directly adhered, under a certain technological condition, to the surface of an artificial board, timber and the like which have antibacterial requirements. After adhesion, the surface of a product needs no finishing treatment, and the surface has good antibacterial performance, heat resistant, wear resistance and the like.

Description

Technical field [0001] The present invention is a building decorative material and is a kind of antibacterial melamine formaldehyde resin.It is widely used in surface decorative materials such as indoor decorative materials, furniture, flooring, etc. with antibacterial requirements. Background technique [0002] The existing melamine formaldehyde resin immersion products are mainly based on impregnated ordinary decorative paper, and a small part of the use of impregnated decorative paper processing wood, thin wood and other products. Because the main difference between thin wood and decorative paper is the existence of its existence, the horizontal horizontal wood horizontallyThe tattoo resistance strength is low, and it is easily damaged during impregnation and veneer operation. After the surface of the surface, the surface is prone to cracks, especially when the surface temperature is high, the more obvious the defects produced.No antibacterial performance.Therefore, the existi...
