Problems solved by technology

[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. La

Abstract

The invention relates to the technical field of PVC materials, in particular to a tasteless PVC modified material and a preparation method thereof. The tasteless PVC modified material is prepared from the following raw materials in parts by weight: 80 to 120 parts of PVC resin, 50 to 70 parts of a plasticizer, 20 to 30 parts of a filler, 3 to 7 parts of a tasteless heat stabilizer, 0.6 to 1 part of a lubricant and 1 to 2 parts of a deodorant. According to the tasteless PVC modified material disclosed by the invention, by adopting the raw materials and strictly controlling the weight proportion of the raw materials, the properties of the prepared tasteless PVC modified material exceed the national standard, and the tasteless PVC modified material is tasteless, environment-friendly, excellent in temperature resistance and weather resistance, high in strength, excellent in shock resistance, good in flame retardant efficiency, good in processing performance and excellent in combination property.

Description

Technical field [0001] The invention relates to the technical field of PVC materials, in particular to an odorless PVC modified material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the earliest industrialized and widely used general thermoplastics. It has the advantages of light weight, high strength, insulation, flame retardant, corrosion resistance, excellent comprehensive performance, low price and wide raw material sources; but also There are the following shortcomings: 1. Poor toughness, easily brittle and cracked 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 use for general PVC products is -15°C, soft The lower limit of the use of PVC is -30℃; 2. The thermal stability is poor. It starts to decompose HCl at 100℃, and decomposes more rapidly when it is higher than 150℃. The melting temperature of PVC i...
