Problems solved by technology

The composite ecological wood has a certain waterproof, moisture-proof, insect-proof, and fire-proof effects, but it is not environmentally friendly. Its composition contains toluene, which is harmful to the human body, and the flame-retardant effect is not good. When it burns, it generates a lot of smoke. It is easy to pollute the environment when it is discharged into the air. In addition, the recyclable effect of the composite ecological wood is poor

Abstract

The invention relates to the technical field of ecological wood foamed materials, and provides an environment-friendly ecological wood and negative oxygen ion powder blended closed-cell secondary foamed material and a preparation method thereof. Negative oxygen ion powder of the environment-friendly ecological wood and negative oxygen ion powder blended closed-cell secondary foamed material can be effectively combined with vinyl chloride-vinyl acetate copolymers, an impact resistant modifier and plant fiber under the situation of maintaining high biological activity, the dispersity of the negative oxygen ion powder on vinyl chloride-vinyl acetate copolymer molecules is effectively promoted, all original excellent physical properties of vinyl chloride-vinyl acetate copolymers can be effectively maintained, enough negative oxygen ions can be effectively and fully released, a prepared finished product can continuously release negative oxygen ions in a static state, the concentration reaches up to 1,500 per cubic centimeter, the prepared finished product can continuously release the negative oxygen ions in a dynamic state, the concentration reaches up to 8,000 per cubic centimeter, the environmental air quality can be improved, human health is promoted, and the preparation method of the foamed material is easy to operate, easy to achieve and suitable for large-batch production and use.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to an environmentally friendly ecological wood / negative oxygen ion powder blended closed-cell secondary foaming material and a preparation method thereof. Background technique [0002] At present, the decorative boards used for furniture, interior and exterior decoration, etc. generally use wooden boards, particle boards, density boards, fiber composite boards, gypsum and fiber composite boards, and fireproof boards. Among them: wooden boards, particle boards, density boards, fiber composite boards, gypsum and fiber composite boards have poor flame retardancy and fire resistance, and the amount of smoke generated during the combustion process is large, which cannot meet the requirements for flame retardancy and fire protection. limitations, and not water-resistant, not moisture-proof. The fireproof board is generally a fireproof sandwich panel made of metal as the panel a...
