D. maintenance typing.

Available coupling agent carries out modification to strongthener before stirring.

After the d step, also have the planarizing substrate surface, paste ornament layer 2, spray or brush flame-proof abrasion-resistant layer 3.

Described spraying or brush wearing layer 3 for being to add in 100 the polyester fully to stir after weight is 2～5 solidifying agent in weight adds weight again and is 0.5～3.5 promotor and makes behind the coating spraying or brush after stirring.

The present invention has following advantage:

1. mainly be based on industrial solid castoff---flyash, produce in conjunction with other macromolecular compound.The rational proportion of nanometer, micropowder coal ash, make its light weight high-strength, have all functions that timber had such as to saw, can dig, can bore, can follow closely, can paste, can substitute existing glued board, density board, fiberboard, shaving board, Blockboard fully, be applied to fields such as furniture making, decorations.Not only cost is low, cheap, and main is to prevent that a large amount of trees from being cut down, and has protected the ecological natural environment;

2. the characteristics that have flame-proof abrasion-resistant meet the fire protection requirement of furniture, decorations;

3. good water-proof effect, can prevent bloated, contract, phenomenon such as warpage, cracking, long product lifecycle;

4. product surface has ornament layer, can avoid making the worry of whitewashing lacquer painting in furniture, the decorations and bringing, the toxic substance contaminate environment in preventing to coat with lacquer;

5. contained aluminium sesquioxide has the far infrared radiation function in the flyash, has the effect of decomposing airborne pathogenic bacteria and toxin.
