Use the utility model discloses floor intensity height, the wearability of producing are good, and thermal insulation performance is good, and no plasticizer spills over, and the solution has the plastic floor on the above -mentioned technical defect that the floor trade exists, the wooden floor of fungible now.
Description
Technical field
This utility model relates to plastics field, relates in particular a kind of foam Combined floor of silicate modified PVC layer of microballon that contains.
Technical background
Current domestic floor annual requirement is greatly about 1,500,000,000 square metres of left and right, mainly taking wood floors and plastic floor as main, wood floors are divided into solid wooden floor board, solid wooden compound floor and reinforced composite floorboard, solid wood and solid wooden compound floor account for more than 40%, reinforced composite floorboard 50%, especially family's installed floor is all to adopt solid wooden compound floor and consolidated floor substantially, the rich talent of small part uses solid wooden floor board, because solid wood and solid wooden compound floor main raw material(s) are wooden boards, content of formaldehyde is less, but price is more expensive. Reinforced composite floorboard is to adopt wood powder, adhesive and glued board to make, and content of formaldehyde is higher. China is a country that timber resources is poorer, China's afforestation rate only has 16.5% at present, only be equivalent to the World Forests coverage rate and be 31.7% 52%, area of woods is only equivalent to 1/8 left and right of world's Per capita area per capita, a large amount of felling timber not only reduces timber resources and has also destroyed ecological environment, has brought great harm to human habitat. Country has carried out to prohibit to the use of natural forest resource and has cut down and limit is cut down policy for this reason, and new policy, " Green Development is forbidden the harvesting of wood and tree grafting growth " are put into effect again in country's 13 planning. Therefore the raw material of producing from now on wood floors can be fewer and feweri, price also can be more and more expensive, can cause great market has openings to Floor Industry very soon, the fitment material for family of therefore researching and developing alternative wood floors is very important, is also material development person's top priority.
Jin Liangnian lot of domestic and international enterprise begins one's study and develops the PVC plastic floor replacement wood floors of various formula different structures for this reason, divide main formula to be divided into foaming floor and the floor of not foaming by technique, current foaming floor mostly is AC foaming, AC foaming floor cell uniformity is poor, intensity is lower, wear no resistance, service life is short, after AC blowing agent decomposes, discharge oxynitrides and carbon monoxide, document announcement has mutagenesis, can produce stimulation toxic, there is corrosion, contact scar air, suck human body or contact raw material and can cause major injury or lethal, for head it off, the present invention proposes to apply microballon blowing agent PVC is foamed, the PVC aperture of microballon blowing agent foaming is even, density is moderate, yield rate is high, also improve intensity and the anti-wear performance of material simultaneously, and nontoxic, environmental protection, improve from structure on the other hand, enhancement layer all add up and down microballon foamed damping layer, increase the elasticity on floor, the casing play on protection floor is injury-free, extends the service life on floor.
Divide and be mainly divided into the common extrusion molding of individual layer ' structure, homogeneous penetrating structure and multi-layer combined structure by structure, in the production process of PVC floor, need to add the heavy metal salt stabilizing agent such as plasticizer and lead, tin of gross weight 50% left and right, in use plasticizer and heavy metal stabilizer can constantly be separated out, slowly be discharged in indoor environment, there are esophagus, respiratory tract, three kinds of approach of skin to enter human body by entering human body, all can cause serious injury to human reproduction's system, internal system and nervous system, even the fetus in pregnant woman's abdomen be damaged. Also have just above-mentioned reason to cause PVC floor also not obtain people's accreditation in house ornamentation field, market consumption is little. The present invention has adopted microballon foaming multi-layer compound structure, do not add plasticizer, be provided with UV cured layer at floor top layer simultaneously, can well stop like this overflowing of low-molecular material and additive in PVC floor, solve the problem of PVC floor wholesomeness from structure, also can save a large amount of costs.
