Description
Technical field
The invention belongs to industrial solid castoff field of comprehensive utilization, be specifically related to a kind of foaming imitated wood floor board utilizing coal ash for manufacturing standby。
Background technology
In recent years, the electric power industry development of China is rapid, and coal resources consumption constantly increases, and causes the discharge capacity of flyash to sharply increase year by year。According to " Chinese Resources comprehensive utilization annual report 2014 " statistics, nineteen ninety-five, China's flyash annual production is 1.25 hundred million tons, and the annual production of 2000 is 1.5 hundred million tons, within 2010, is 4.8 hundred million tons。And 2013, China creates the flyash discharge of 5.8 hundred million tons, and relatively nineteen ninety-five adds 4.64 times。Expecting the year two thousand twenty accordingly, total heap of flyash high-volume will more than 3,000,000,000 tons。At present, China is that world's flyash produces maximum countries, and its annual discharge capacity is equivalent to 2 times of China's domestic waste total release。
Huge flyash discharge can cause serious environmental pollution and harm。First, flyash stacking can take a large amount of valuable land resource。Fly ash grain is tiny, is therefore readily formed dust raising phenomenon, causes dust pollution, and health is produced harm。Additionally, flyash is after rainwater leaching, also can mix the soil near flowing into, river etc. with water, cause serious environmental pollution。How to reduce the pollution of flyash, flyash is turned waste into wealth, promote that the efficient circulation of flyash utilizes, be a problem merited attention。
Wood plastic composite is the class composite board material being in recent years surging forward both at home and abroad, and it is by sheet material shape through hot extrusion molding after plastics and wooden powder being mixed by a certain percentage。Because its performance is more excellent relative to normal wood material, therefore it is widely used in the industries such as building materials, furniture, logistics packaging。
A kind of energy-conserving and environment-protective composite floor board and manufacture method thereof as disclosed in Chinese patent that publication number is 103572940A, it includes makes with Wooden veneer, respectively at the panel of the upper and lower surface on floor and base plate, it is sandwiched between central layer at panel and base plate, it is characterized in that what described central layer polyurethane foam material was made, tongue-and-groove or the joint tongue of splicing mutually is had in the side of floor surrounding, this invention can be effectively moistureproof, and there is function of heat insulation, but wherein only have the foamed core web of monolayer as support, easily it is deformed, and the performances such as moisture-proof heat-insulation are also not as, additionally, foam need to carry out the inserts of discontinuity when producing after, pressing and the follow-up demoulding, mortises etc. operate, production cycle is long, production efficiency is low。
Inventor had once submitted one about the coal ash for manufacturing patent application (application number is 201410114555.9) for the method for imitated wood floor board in March, 2014。This invention utilizes flyash as inserts to prepare imitated wood floor board, there is the function of good damp-proof and fireproof insect-pest, and its heat-proof quality is excellent, is in use unlikely to deform。Showing in further research and development of products and feedack, prepared imitated wood floor board sheet material deadweight is higher, is unfavorable for marketing。
