Description
Technical Field
The invention relates to the technical field of stone-plastic floors, in particular to an SPC stone-plastic floor produced by an ink-jet technology and production equipment thereof.
Background
The traditional ceramic floor, solid wood floor and composite floor have the phenomena of ice-hard foot feel, easy deformation, overproof formaldehyde and the like, can not meet the requirements of people, and urgently needs an indoor floor which is soft, difficult to deform and environment-friendly. The LVT floor, namely the PVC floor, is produced at the same time, and meets the requirements of people; the PVC flooring is mainly composed of a polyvinyl chloride material, and is widely used in various aspects of homes and businesses due to its rich color and variety of colors. LVT floors are a new type of light floor finishing material that is very popular in the world today, also known as "light floors". The product is a widely popular product in China and south China, is popular abroad, enters the Chinese market from the beginning of the 80 s, is generally accepted in domestic large and medium cities so far, and is widely used in various places such as indoor families, hospitals, office buildings, factories, public places, supermarkets, businesses, stadiums and the like.
The English name of the SPC floor is stone plane composite, and the Chinese name is stone crystal floor or stone plastic floor. The SPC floor is popular in Europe and America at first, China is introduced now, and the SPC floor becomes a more popular decorative material in the market, and compared with the LVT floor, the stability and the shrinkage resistance of the SPC floor are far higher than those of the LVT floor. The shrinkage rate of LVT floor boards is < =0.15%, and the shrinkage rate of SPC floor boards is < =0.08%, so that the floor boards made of the materials rapidly take the domestic and foreign mainstream markets in recent years.
However, in the current situation, in the conventional process for producing the SPC floor, a manufacturer needs to purchase or make a color film from a printing factory, and if the color film in the printing factory is purchased, the product is not personalized, and all manufacturers can purchase the color film, so that the SPC floor manufacturer can only perform batch production and compete at a low price. In addition, the order volume of the color film sold by a common printing factory is 3000 meters, and if the order of the factory does not have the volume, the residual color film is not digested, so that the stock overstock is caused. If an SPC floor manufacturer needs to research and develop a color film with a new pattern, the color film printing manufacturer needs to manufacture four rollers (one roller and one color) and manufacture the color film with the length of not less than 10000 meters, the development cost of a single new product is higher than 50000 Yuan Min Cin, and the production cost is too high.
