PVC modified material for semi-transparent LED light strip and preparation method thereof

Abstract

The invention relates to the technical field of PVC modified materials and in particular to a PVC modified material for a semi-transparent LED light strip and a preparation method thereof. The PVC modified material for the semi-transparent LED light strip comprises the following raw materials in parts by weight: 80-120 parts of PVC resin, 45-70 parts of a plasticizer, 1.4-2.2 parts of a stabilizer, 0.4-0.8 part of a light shielding agent, 0.4-0.8 part of titanium dioxide, 0.1-0.3 part of a whitener, 0.6-1.0 part of a liquid lubrication prescription and 0.4-0.8 part of a lubricant. The PVC modified material for the semi-transparent LED light strip provided by the invention is environmental-friendly, excellent in temperature resistance and weather resistance, high in strength, excellent in impact resistance, good in flame retardant effect, excellent in processing property and excellent in 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 translucent LED light strip 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 ...

[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 LED light strips for curtains have defects such as poor light transmission, which limits their use to a certain extent.
