This utility model relates to the field of milk refrigerator technology, and more particularly to a milk refrigerator with anti-fog function. It includes a cabinet, with a door connected to one side of the cabinet. The door includes an outer door panel, a sealing strip, an inner door panel, double-layered glass, and an anti-fog drying aluminum strip. The double-layered glass includes an outer glass layer and an inner glass layer. The anti-fog drying aluminum strip is disposed between the outer and inner glass layers, and an intermediate layer is also disposed between the outer and inner glass layers. This utility model has low operating costs. By setting up double-layered glass and incorporating the anti-fog drying aluminum strip within the double-layered glass, it can absorb water vapor within the double-layered glass, preventing water vapor from condensing into fog and avoiding fogging caused by humidity changes. This maintains the clarity and transparency of the double-layered glass, and improves its thermal insulation, sound insulation, and heat insulation performance.

The invention discloses a production process of a new material for paper decoration, and relates to the technical field of decoration material production, the dependence on natural mineral products is abandoned, renewable plant fiber paper is adopted as a core base material, the radioactive risk of a raw material source is eliminated, and the environmental safety of long-term indoor use of the material is ensured; in order to solve the problems that paper is insufficient in strength and poor in weather resistance, a composite modifier containing waterborne polyurethane resin and nano silicon dioxide is designed, the modifier fully permeates into the interior and gaps of a paper fiber network through an ultrasonic-assisted impregnation technology, and in the subsequent drying and hot pressing process, the strength of the paper is greatly improved. The resin is crosslinked and has a synergistic effect with the nanoparticles, a compact organic-inorganic hybrid protection layer is formed on the surfaces of the fibers and among the fibers, and the protection layer obviously enhances the mechanical strength, wear resistance and moisture resistance of the paper, so that the paper meets the use requirements of decorative plane materials, and meanwhile, unification of safety and economical efficiency is realized.

This application relates to the technical field of fiberglass reinforced plastics (FRP), and in particular to an unsaturated polyester resin for FRP, a method for preparing the same, and FRP. The unsaturated polyester resin comprises the following raw materials in parts by weight: diols: neopentyl glycol 22-30 parts, 2,2-diallyl bisphenol A 2-4 parts, and bisphenol fluorene 5-9 parts; diacids: isophthalic acid 5-15 parts, terephthalic acid 5-15 parts; acid anhydrides: phthalic anhydride 3-15 parts, maleic anhydride 5-17 parts; toughening agent: double-ended hydrogen-capped silicone oil 5-9 parts; platinum catalyst: the amount of platinum catalyst added is 30-150 ppm of the total mass of 2,2-diallyl bisphenol A and double-ended hydrogen-capped silicone oil; diluent 25-45 parts; polymerization inhibitor 0.01-0.06 parts. It has the advantage of improving the hardness and toughness of the unsaturated polyester resin, thus enhancing its corrosion resistance.
