step four: coating an inorganic material grade A non-combustible composite heat-insulating material protective layer 5 on the upper surface of the organic heat-insulating core material layer 1, embedding composite basalt mesh cloth or alkali-resistant glass fiber mesh cloth or metal mesh or an inorganic heat-insulating protective mesh layer 6 with fire-proof performance in the inorganic material grade A non-combustible composite heat-insulating material protective layer 5, and then maintaining;
step five: trimming and packaging, and warehousing finished products.
The second preparation method of the utility model comprises the following steps:
the method comprises the following steps: a plurality of dovetail grooves 2 are formed on a modified polystyrene extruded foam board or a polystyrene extruded foam board of an organic heat-insulation core material layer 1;
step two: preparing a modified sodium silicate solution, wherein 10-50 parts of the sodium silicate solution and 30-100 parts of water are used; 5-30 parts of sodium fluosilicate, 1-30 parts of sodium hydroxide and 2-40 parts of sodium phosphate for later use;
step three: coating a slurry material consisting of the modified sodium silicate solution and slag powder or yellow sand or silica sand or consisting of cement and polystyrene foam particles or closed-cell perlite or flaked pottery, fly ash, short fibers and calcium hydroxide on the upper surface of the modified polystyrene extruded foam board or polystyrene extruded foam board layer (1) in the step one to form an A-grade non-combustible composite heat-insulating material protective layer (5), and embedding basalt gridding cloth or alkali-resistant glass fiber gridding cloth or metal mesh or an inorganic heat-insulating protective net layer (6) with fire-proof performance in the inorganic material A-grade non-combustible composite heat-insulating material protective layer (5) to form a semi-finished product, namely the non-dismantling composite heat-insulating template is maintained;
step four: trimming and packaging, and warehousing finished products.
