Problems solved by technology

[0003] When the composite board is used in the kitchen, because the temperature in the kitchen is high during cooking, it is required that the composite board has good heat dissipation performance. Excellent anti-oil performance, the traditional composite board cannot have good heat dissipation and anti-oil performance at the same time, therefore, the application of the composite board is limited

Abstract

The invention discloses an anti-fouling heat dissipation composite board and a preparation method thereof, and relates to the technical field of new materials. The preparation method comprises the following steps of: firstly, sequentially reacting pretreated straws subjected to alkali boiling, peeling and crushing with glycidyl methacrylate and polyethyleneimine under the action of an emulsifier OP-10 and benzoyl peroxide to prepare modified straws; then mixing the modified straws with a copper ion solution, and carrying out micro-crosslinking in an organic solvent by using carbon dioxide to obtain mixed modified straws; then mixing the mixed modified straws with an isocyanate adhesive, spreading the mixture between two polypropylene micro-porous membranes, and carrying out hot press molding to obtain a composite board blank; and finally treating the composite board blank with dopamine, then fumigating the composite board blank with an acid solution, and drying the composite board blank to obtain the anti-fouling heat dissipation composite board. The anti-fouling heat dissipation composite board prepared by the invention has excellent heat dissipation performance and good oil stain resistance.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an antifouling and heat dissipation composite board and a preparation method thereof. Background technique [0002] Composite panels are generally divided into: metal composite panels, wood composite panels, color steel composite panels, rock wool composite panels and so on. Composite panels are widely used in daily life due to their excellent properties. [0003] When the composite board is used in the kitchen, because the temperature in the kitchen is high during cooking, it is required that the composite board has good heat dissipation performance. The traditional composite board cannot have good heat dissipation and oil resistance performance at the same time, so the application of the composite board is limited. Contents of the invention [0004] The object of the present invention is to provide an anti-fouling and heat-dissipating composite board and a preparation...
