Abstract

The invention discloses a decorative laminated board with a bacteriostatic function and a preparation method thereof. The decorative laminated board comprises base paper, core paper and surface paper, and a melamine resin layer containing a bacteriostatic agent is coated on the surface paper. The preparation method comprises: dipping the surface paper, the core paper and the base paper in a thermosetting material respectively at first, and then performing drying under the condition that the temperature is 90-110 DEG C; coating a layer of melamine resin containing a bacteriostatic agent on the surface of the dried surface paper, and performing drying again; and placing the core paper and the surface paper on the base paper in sequence, performing pressing for 30-90 minutes at 135-150 DEG C and 15-20MPa, lowering the temperature to below 40 DEG C to obtain a semi-finished product, and finally, trimming and sanding the semi-finished product to obtain a decorative laminated board. The board prepared by virtue of the method can effectively inhibit the growth of microorganisms on the surface of the board and prevent propagation of diseases, and the rate of killing moulds and pathogenic bacteria (such as colibacillus and staphylococcus) on the surface of the board reaches 95% or higher and accords with and exceeds a national standard.

Description

technical field [0001] The invention belongs to the field of decorative materials, and relates to a decorative laminate, in particular to a decorative laminate with antibacterial function on the surface and a preparation method thereof. Background technique [0002] Microorganisms such as harmful bacteria, fungi and viruses in nature are the main reasons for human beings to suffer from infection and induce diseases. With the continuous improvement of people's awareness and requirements of the living environment, especially the awareness of health is also increasing. The production of antibacterial materials has become an emerging industry. Thermosetting resin impregnated paper high-pressure laminated boards are widely used as decorative boards in areas that are in direct contact with people, such as interior decoration, furniture, kitchen cabinets, laboratory countertops, and exterior walls. But the surface of the existing decorative laminated board is easy to breed bacter...
