A self-adhesive floorboard with water-resistant glue comprises from a top to a bottom sequentially a main body layer, an isolation layer and the water-resistant glue, wherein each component proportion of component composition of the water-resistant glue based on a weight percentage is: 34-38% for a styrene-isoprene-styrene block copolymer, 46.4-50.4% for C5 hydrogenated petroleum resin, 13-17% for cycloalkyl rubber extender oil and 0.5-0.6% for a hindered phenol antioxidant. The isolation layer between the main body layer and the water-resistant glue is a PVC film of OPHR. The water-resistant glue of the PVC self-adhesive floorboard with the water-resistant glue is provided with a water-resistance function, and can prevent a plasticizer from drifting away from the PVC floorboard to affect stickiness of the water-resistant glue.

The oxynitride has a chemical formula of AxByOzN2/3x+4/3y−2/3z:R, wherein A is one or more elements selected from the group consisting of Be, Mg, Ca, Sr, Ba, and Zn; B is one or more elements selected from the group consisting of Si, Ge, Zr, Ti, B, Al, Ga, In, Li, and Na, and at least contains Si. The oxynitride luminescent material according to the invention is excellent in chemical stability and luminescence property, and act as cyan to red luminescent material applicable to white light LED that excited by ultraviolet or blue light LED. Its excited wavelength is between 300-500 nm, while the emission wavelength at 470-700 nm. With blue or ultraviolet or near-ultraviolet LED, this type of material can be used to produce white light illumination or display light source.
摘要:
The invention provides a high strength stone plastic floor and manufacturing method thereof. The stone plastic floor comprises a PVC substrate and a surface layer on a surface of the PVC substrate. Compositions of PVC substrate comprise: PVC powder from 20 to 35 weight percent, calcium carbonate from 60 to 70 weight percent, stabilizer from 1 to 3 weight percent, flexibilizer from 1 to 3 weight percent, lubricants from 0.4 to 1 weight percent, and colorant from 0.4 to 1 weight percent. The high strength stone plastic floor does not contain plasticizer so environmental risks are completely avoided. The contractility is good. The high strength stone plastic floor is resistant to high temperature and direct sunlight. Compared with conventional stone plastic floor, lifespan of the present invention is prolonged. The PVC substrate of the floor can be combined with different layers and can integrate different advantages of other floors.
摘要:
A wood-plastic PVC floorboard comprises a PVC main body layer and an underlying substrate wood-plastic layer. The PVC main body layer and the wood-plastic layer are stuck together through glue. Lock structures are arranged at two sides of the wood-plastic layer for bonding two adjacent floorboards. Materials adopted by the wood-plastic layer are wood powder, PVC resin powder and stone powder. Water resistance of wood-plastic and flexibility and water resistance of PVC are combined together. An overall product is not only lighter than a prior lock PVC in a mass, but also more stable than the prior lock PVC, and is easier to install. The total product is water-resistant, without a formaldehyde problem of laminate floorboards.
