PVC (Polyvinyl Chloride) modifying material for curtains and preparation method thereof

Abstract

The invention relates to the technical field of PVC (Polyvinyl Chloride) materials, in particular to a PVC (Polyvinyl Chloride) modifying material for curtains and a preparation method thereof. The PVC modifying material for the curtain is prepared from the following raw materials in parts by weight: 80 to 120 parts of high-polymerization-degree PVC resin, 45 to 65 parts of plasticizer, 5 to 15 parts of ground calcium carbonate, 10 to 15 parts of light calcium carbonate, 2 to 4 parts of stabilizer, 1 to 3 parts of water-proofing agent, 0.5 to 1.5 parts of modifying agent, 0.6 to 1.0 part of anti-ultraviolet agent, 0.3 to 0.7 part of antioxidant, 0.3 to 0.7 part of anti-blushing agent and 0.4 to 0.8 part of outer lubricant. The PVC modifying material for curtains disclosed by the invention has the advantages of good water-proofing and anti-aging effects, environmental friendliness, excellent temperature resistance and weather resistance, high strength, excellent impact resistance, good flame retarding effect, excellent machining performance and superior comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a PVC modified material for curtains 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 the melting tempera...

[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 PVC products is -15°C, and the lower limit of soft 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. The melting temperature of PVC is about 210°C; 3. The viscosity of PVC is extremely high and its fluidity is extremely poor, which limits its use to a certain extent.

[0003] However, the existing PVC materials for curtains have defects such as poor waterproof and anti-aging performance, and easy to change color, which limits its use to a certain extent.
