Self-insulation wallboard and preparation method thereof
The invention relates to the technical field of a building insulation material, and especially relates to a self-insulation wallboard and a preparation method thereof. According to the self-insulation wallboard, fly ash, river sands, quartz sand, corn straw, straw, sawdust, cement and fiber are combined for preparation, better improvement on the performance of the raw materials can be realized, silicon element content and iron element content in quartz sand and fly ash are restricted, raw material quality can be improved from the raw materials aspect, the technical parameter in a subsequent preparation technology is combined, so that orientation modification treatment on each performance of the raw materials can be carried out, flexural compressive strength of the self-insulation wallboard is increased, and freeze thaw performance and thermal insulation performance are enhanced. For detecting the flexural compressive strength and the freeze thaw performance of the product, the compressive strength is 11-17Mpa, the flexural intensity is 3.3-5.7Mpa, refrigeration is carried out for 240 hours at temperature of -40 DEG C--30 DEG C, intensity change rate is 2-4%, and frost cracking condition can not be generated. Compared with the air-added bricks with same volume, the weight of the self-insulation wallboard is reduced by 30-37%.
