A waterproof, heat-insulating, and flame-retardant coating, which includes auxiliary materials and base materials, and is characterized in that: the parts by weight of the main materials are: 5-16 parts of pentaerythritol, 0.2-6 parts of antimony trioxide, chlorine 0.2 to 6 parts of paraffin wax, 2 to 20 parts of mica, and 2 to 20 parts of sepiolite; the main ingredients include 1 to 11 parts of melamine, and 0.3 to 7 parts of silicon powder; 18 parts, 5 to 40 parts of perlite. The invention is non-toxic, tasteless, safe and environment-friendly, stable in performance, waterproof, heat-insulating and flame-retardant, and can be widely used in walls, roofs, floors, basements, pipes, boards and metals.

The invention discloses a waterproof and anti-deformation easily recyclable corrugated cardboard box, which comprises an outer paper layer, a first corrugated layer, a plastic layer, a second corrugated layer and an inner paper layer fixed sequentially from the outside to the inside, and the plastic layer includes the first corrugated layer. A plastic plate and a second plastic plate fixed on the surface of the first plastic plate, the surface of the first plastic plate is evenly distributed with a number of circular grooves, the circular grooves are filled with desiccant, and the bottom of the circular grooves is provided with a second A circular through hole, a second circular through hole communicating with the first circular through hole is opened on the surface of the second plastic plate. The corrugated box of the present invention is provided with a plastic layer in the two corrugated layers, and a groove is arranged in the plastic layer, and the groove is filled with a desiccant, which can play a certain role on the corrugated box, and the plastic layer of the discarded corrugated box It can be recycled, and the desiccant in the plastic layer can be reused after drying in the drying oven, which saves the cost of use. At the same time, the plastic layer has certain mechanical strength and strong toughness, which can effectively prevent the bending and deformation of the corrugated cardboard.

The invention belongs to the field of interior decorating boards, and discloses a double-layer oriented strand laminated plywood. The double-layer oriented strand laminated plywood is respectively composed of a face board, a core board and a bottom board from top to bottom, which are hot-pressed through an adhesive. The core board is formed by carrying out hot pressing on two intermediate boards through an adhesive. The plywood adopts the double-layer oriented strand laminated structure; and the adhesive with stable service performance is used between every two adjacent layers, has the advantages of high adhesive force, environment friendliness and no pollution, and enhances the properties and market competitiveness of the plywood.
