[0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has light weight, high strength, insulation, flame retardancy, corrosion resistance, It has the advantages of excellent comprehensive performance, low price and wide source of raw materials; but it also has the following disadvantages: 1. Poor toughness, easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. Large, the lower limit of general P

Abstract

The invention relates to the technical field of PVC modified materials, in particular to a PVC modified material for a fireproof ceiling and a preparing method thereof. The PVC modified material for the fireproof ceiling is prepared from, by weight, 80-120 parts of PVC resin, 40-56 parts of a plasticizer, 10-15 parts of light calcium carbonate, 8-12 parts of heavy calcium carbonate, 4-8 parts of a fireproof flame retardant, 3-7 parts of magnesium oxide, 3-7 parts of a heat stabilizer, 2-4 parts of an elastic modifying agent, 0.6-1.0 part of a mildew-proof agent and 0.6-1.0 part of an external lubricant. The PVC modified material for the fireproof ceiling is good in fireproof flame retardant effect, also has the good elasticity and mildew-proof effect, and is environmentally friendly, excellent in temperature resistance and weather resistance, high in strength and excellent in impact resistance, processing performance and comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of PVC modified materials, in particular to a PVC modified material for a fireproof ceiling and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardancy, corrosion resistance, excellent comprehensive performance, low price and wide source of raw materials; but also There are the following disadvantages: 1. The toughness is poor, and it is easy to be brittle when impacted, so it cannot be used as a structural material. In addition, the brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of general PVC products is -15°C. The lower limit of use of PVC is -30°C; 2. Poor thermal stability, it begins to decompose HCl at 100°C, and decomposes more rapidly when it is higher than 150°C, and...
