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

Embodiment 1
[0055] A preparation method of an environmentally friendly ecological wood / negative oxygen ion powder blended closed-cell secondary foaming material, comprising the following steps:
[0056] (1) Preparation of negative oxygen ion premixed powder: 100PHR tourmaline powder, 100PHR Wizard R series plastic / rubber additive 1250 mesh, 5PHR chelating titanate coupling agent, and 100PHR clay are blended and stirred for 12 The temperature was controlled to 80°C during the stirring process, and the negative oxygen ion premixed powder was obtained after the stirring was completed;
[0057] (2) Plant fiber pretreatment: Bake the plant fiber in an oven to reduce the water content of the plant fiber to below 2.5%, weigh 20 PHR of the above-mentioned treated plant fiber with a water content below 2.5%, and put it into a high-speed mixer , add 2PHR chelating titanate coupling agent, stir at high speed for 9 minutes and release;
[0058] (3) Mixing with an internal mixer: 25PHR of plant fiber...
Embodiment 2
[0071] The preparation method of the environmentally friendly ecological wood / negative oxygen ion powder blended closed-cell secondary foaming material described in Example 2 is completely consistent with Example 1, and the difference is that the weight ratio of the raw materials used in Example 2 is as follows:

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, for furniture, interior and exterior decoration and other decorative boards, generally wood board, particle board, MDF, fiber composite board, gypsum and fiber composite board, fireproof board, etc. are used. Among them: wood board, particle board, density board, fiber composite board, gypsum and fiber composite board and other boards have poor flame retardant and fire resistance properties, and the amount of smoke generated during the combustion process is large, which cannot meet the requirements of flame retardant and fire protection grade. limitations, and it is not resistant to water and moisture. Fire-proof sandwich panels are generally made of metal as the panel, flame-re...
