Embodiment 1
[0020] Example 1: Take 100kg of glass fiber, 3kg of gelatinized starch, 2kg of polyvinyl alcohol, and 0.2kg of a mixture of polysilane and siloxane, add 95kg of water to stir, mix and make pulp, and then use vacuum forming to produce a wet billet, forming After the wet base surface evenly smears the thick interface treatment agent of 5mm, wherein the interface treatment agent of 3mm thickness has penetrated under the wet base surface at last, and 2mm is positioned at the surface of wet base, and described interface treatment agent is made of cement 30 parts (parts by weight) , 40 parts of styrene-acrylic emulsion (parts by weight), 0.05 parts of AT-75 alkali-swellable thickener (AT-75 is a cross-linked polymer emulsion thickener formed by copolymerization of acrylate and methacrylate), hydrophobic It is prepared by stirring uniformly 2 parts (parts by weight) of the mixture of polysilane and siloxane and 7.2 parts (parts by weight) of water. Finally, after the wet billet is dr...
Embodiment 2
[0021] Example 2: Take 100kg of ceramic fiber, 2kg of gelatinized starch, and 0.1kg of hydrogen polysiloxane, add 100kg of water to stir, mix and make pulp, and then use vacuum forming to produce a wet billet, and evenly smear the surface of the formed wet billet 4mm thick interface treatment agent, wherein the thick interface treatment agent of 2mm has penetrated under the wet base surface at last, and 2mm is positioned at the surface of wet base, and described interface treatment agent consists of 40 parts (weight parts) of cement, 40 parts (weight parts) of styrene-acrylic emulsion parts), 0.1 parts (parts by weight) of T-900 alkali-swellable thickener, 3 parts (parts by weight) of hydrophobic agent hydropolysiloxane and 31 parts (parts by weight) of water are evenly prepared by stirring. Finally, after the wet billet is dried at about 110°C, it is cut into finished products after post-processing.
Embodiment 3
[0022] Example 3: Take 100kg of rock wool fiber, 10kg of gelatinized starch, 0.85kg of polysilane / siloxane, and 0.15kg of methyl silicate, add 90kg of water to stir, mix and make pulp, and then use vacuum forming to produce a wet billet , the surface of the wet billet after forming is evenly coated with an interface treatment agent, the thickness of the interface treatment agent is 5mm, and finally the interface treatment agent with a thickness of about 3mm has finally penetrated into the surface of the wet billet, and 2mm is located on the surface of the wet billet. The interface treatment agent Consists of 60 parts of cement, (parts by weight) 0.15 parts (parts by weight) of AT-75 alkali swelling thickener (AT-75 is a cross-linked polymer emulsion thickener formed by copolymerization of acrylate and methacrylate) 3 parts (parts by weight) of a mixture of water-repellent polysilane and siloxane, 2 parts (parts by weight) of methyl silicate, 70 parts (parts by weight) of styren...
