PVC modified material for beach chair cloth and preparation method thereof

Abstract

The invention relates to the technical field of PVC modified materials, and in particular relates to a PVC modified material for a beach chair cloth and a preparation method thereof. The PVC modified material for the beach chair cloth is prepared from the following raw materials in parts by weight: 80-120 parts of PVC resin, 40-60 parts of a plasticizer, 3-7 parts of light calcium carbonate, 3-7 parts of a modifier, 2-4 parts of a stabilizer, 1-2 parts of a mould-proof agent, 0.6-1.0 part of a fungusproof agent, 0.5-1.5 parts of an anti-radiation agent, 0.3-0.7 part of an external lubricant and 0.2-0.4 part of an internal lubricant. The PVC modified material for the beach chair cloth has good mould-proof, fungusproof and anti-radiation effects, is environment-friendly and has excellent temperature resistance and weather resistance, high strength, excellent shock resistance, good flame retardant effect, excellent processability and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a PVC modified material for beach chair fabric 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 melti...

[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.

People often use methods such as adding fillers, elastomers, plasticizers, heat stabilizers, processing aids, heat-resistant modifiers and flow modifiers to improve the performance of PVC, but there is no such method that is suitable for beach chairs in the prior art. Fabric PVC material
