The present application relates to the technical field of a floor composite material, and more particularly, the present application provides a composite material containing a PVC pre-coating film and a preparation method therefor. In the first aspect, the present application provides the method for preparing the composite material containing the PVC pre-coating film. The method comprises preparing the PVC pre-coating film by utilizing a PVC transparent film layer and a radiation-cured coating; performing high-temperature press fit on the PVC pre-coating film, a substrate material and a printed decorative layer; and then performing cooling and forming treatment to obtain the composite material containing the ultra-wear-resistant and easy-to-clean PVC pre-coating film.

The present application relates to the technical field of floor surface decoration materials, and particularly provides a multi-coating radiation-cured pre-coating film and a preparation method therefor. The first aspect of the present application provides the multi-coating radiation-cured pre-coating film, which sequentially comprises a flexible transparent film layer and a radiation-cured coating from bottom to top, wherein the radiation-cured coating sequentially comprises a radiation-cured elastic primer layer and a radiation-cured wear-resistant finish paint layer from bottom to top, the at least one radiation-cured elastic primer layer and the at least one radiation-cured wear-resistant finish paint layer are arranged, and the radiation-cured elastic primer layer equentially comprises a radiation-cured elastic wear-resistant primer layer and a radiation-cured elastic matte/bright primer layer from bottom to top.

Multi-coating radiation-cured pre-coating film and preparation method thereof

A super-wear-resistant self-cleaning coating, comprising first elastic finish coat and second self-cleaning finish coat. The first elastic finish coat comprises, by mass, 10-60 parts of a two-functionality-degree polyurethane acrylic resin A, 2-7 parts of an initiator A, 10-60 parts of an acrylate monomer A, and 3-40 parts of an additive A. The second self-cleaning finish coat comprises, by mass, 2-30 parts of an acrylic acid-modified organic silicon resin with inorganic powder affinity, 0.3-3 parts of high-hardness micro-powder particles, 2-20 parts of a two-functionality-degree polyurethane acrylic resin B, 10-40 parts of a multi-functionality-degree polyurethane acrylic resin B, 15-45 parts of an acrylate monomer B, 2-7 parts of an initiator B, and 3-40 parts of an additive B. Further disclosed is a preparation method for the super-wear-resistant self-cleaning coating.

Super-wear-resistant self-cleaning coating and preparation method therefor

A device for servicing live power lines, including: a main body, two primary mechanical arms, two telescopic arms, a terminal device, an auxiliary mechanical arm, and a monitoring system. A travelling wheel mechanism, an equipotential wheel, and a first clamping jaw are disposed on the upper end of each telescopic arm. The two primary mechanical arms are symmetrically disposed on two sides of the main body, respectively. The two telescopic arms are vertically disposed on two ends of the main body, respectively, and are capable of telescoping upward and downward. The auxiliary mechanical arm is disposed and adapted to move transversely on the main body. The main body is driven by the travelling wheel mechanism to travel on the high voltage transmission line. The first clamping jaw clamps the high voltage transmission line for locating the main body.
