The invention discloses silicon dioxide loaded nano-silver waterborne antibacterial paint and a preparation method thereof, and belongs to the field of chemical paint. The paint is prepared from the following components: water, acrylic resin, polyurethane resin, a porous silicon dioxide loaded nano-silver antibacterial agent, a dispersant, a curing agent, a de-foaming agent, a film-forming auxiliary agent and a flatting agent. According to the silicon dioxide loaded nano-silver waterborne antibacterial paint, nano-silver is loaded in porous silicon dioxide, so that the effect of protecting the nano-silver is realized; a releasing speed of the nano-silver can also be slowed down to a certain extent, so that the antibacterial time of the paint is more durable. A pore channel space is limited and a special preparation process is adopted (under the protection effect of PVP (Polyvinyl Pyrrolidone)), the size of the nano-Ag is controlled to be only 3nm to 5nm, so that the specific surface area of the nano-Ag is greatly increased. Furthermore, a special pore channel of the porous silicon dioxide has a fixation effect on the nano-Ag, so that the nano-Ag is not easy to aggregate and has good dispersity in a solution, and the antibacterial performance of the paint is improved.

When extreme conditions such as overheating occur in the battery module, on one hand, heat on the stacking surfaces of the batteries is transferred to side plates for heat dissipation through the heat conduction pieces, on the other hand, the heat absorption layers on the heat conduction pieces can absorb and take away most of the heat. Therefore, the problem of thermal runaway caused by the heat accumulation of the battery module is solved effectively due to double action of the heat transferring effect of the heat conduction pieces and the heat absorption effect of the protection layers.

The stone-imitated finishing material comprises the wall body; an interface layer is covered on the surface of the wall body; a layer of steel wire gauze is covered on the outer surface of the interface layer; a stone-imitated material layer is covered on the outer surface of the steel wire gauze; and a hydrophobic layer is coated on the outer surface of the stone-imitated material layer. Through the method provided by the invention, the stone-imitated finishing material has the advantages of low cost, high construction speed, easiness in maintenance, long service life and the like. The stone-imitated finishing material is compounded by renewable resources, can effectively replace natural stones so as to alleviate pollution and damage on natural resources caused by exploitation of the natural stones, also does not cause radiation pollution like the natural stones do, is lower than the natural stones in cost by more than 70%, can overcome the limitation that dry-hang flat plate stone materials can not be used for high-rise decoration, can achieve a stone material decoration effect on buildings with any height, and can greatly lower transportation costs and investment of capital construction.
