The invention relates to the technical field of building materials, and particularly relates to a heat-insulating flame-retardant building material and a preparation method thereof. The building material comprises the following components in parts by mass: 40-60 parts of artificial light-weight aggregate, 40-60 parts of an inorganic gelling material, 10-20 parts of a nano cement additive, 0.2-1.2 parts of anti-cracking fibers, 0.5-2.5 parts of a defoaming agent, 0.5-2.5 parts of a dispersant, 10-20 parts of water, 6-8 parts of calcium carbonate whiskers, 8-10 parts of magnesium salt whiskers, 0.3-0.8 part of a mortar water retaining agent and 0.2-0.5 part of a water reducing agent. The building material has the beneficial effects that the compressive strength and the flexibility of the building material are improved by adding the calcium carbonate whiskers and the magnesium salt whiskers and further improved by adding the anti-cracking fibers, so that the technical deficiencies that an inorganic heat insulating material is high in hardness and easy to drop are well overcome.

The invention discloses a preparation method of a high-fastness elastic jean laminated fabric, the laminated fabric comprises a pretreated base fabric, a surface fabric and a TPE film, the surface fabric is laminated on the pretreated base fabric through a hot melt adhesive, and the TPE film is laminated on the surface fabric through the hot melt adhesive; the pretreated base fabric is prepared by modifying a base fabric and a surface modifier; the surface modifier is prepared from the following raw materials in parts by weight: 5 to 7 parts of flame retardant, 10 to 12 parts of water-absorbing microspheres, 8 to 10 parts of aluminum chloride hexahydrate, 25 to 30 parts of absolute ethyl alcohol, 4 to 6 parts of formamide, 4 to 6 parts of tetraethyl orthosilicate and 10 to 14 parts of 1, 2-epoxypropane. According to the high-fastness elastic jean laminated fabric and the preparation method thereof, the process design is reasonable, operation is simple, a three-layer laminated fabric with excellent flame retardant property is prepared, and the laminated fabric is high in stiff and smooth property, can be widely applied to the field of clothing, and is relatively high in practicability.
