Polyvinyl chloride soft foam plastic coiled material and preparation method thereof

Abstract

The invention discloses a polyvinyl chloride soft foam plastic coiled material and a preparation method thereof. The polyvinyl chloride soft foam plastic coiled material comprises the following components in parts by weight: 80-90 parts of polyvinyl chloride resin, 20-30 parts of plasticizer, 3-8 parts of foaming agent, 0.5-2 parts of barium stearate, 1-5 parts of butane, 0.5-1 part of zinc oxide and 0.5-2 parts of tetrabromoethane. The preparation method comprises the following steps: stirring and mixing the components in a mixing machine at the stirring speed of 80-100rpm for 15-20 minutes, heating the mixture to 70-80 DEG C, and carrying out foaming reaction, thus obtaining the polyvinyl chloride soft foam plastic. The polyvinyl chloride soft foam plastic disclosed by the invention has the advantages of favorable recovery rate, high tensile strength, high impact resistance and high chemical stability.

Description

technical field [0001] The invention belongs to the field of chemical materials, in particular to a flexible polyethylene foam plastic coil and a preparation method thereof. Background technique [0002] At present, the existing waterproof rolls on the market are basically thick paper or fiber fabrics as the base, and the rolls are made of asphalt or other synthetic polymer waterproof materials. They are mainly used for building walls and roofs. , and highways, tunnels, etc. For the waterproofing of houses and walls, there are already many waterproof and thermal insulation coils, such as polystyrene coils, which are widely used as waterproof and thermal insulation materials for walls and roofs, but the existing materials have good waterproof properties. Insulation effect, but the heat insulation effect is still not ideal. At the same time, it will cause corrosion of the material during long-term use, especially in the external environment; and it is easy to become brittle a...

Problems solved by technology

For the waterproofing of houses and walls, there are already many waterproof and thermal insulation coils, such as polystyrene coils, which are widely used as waterproof and thermal insulation materials for walls and roofs, but the existing materials have good waterproof properties. Insulation effect, but the heat insulation effect is still not ideal. At the same time, it will cause corrosion of the material during long-term use, especially in the external environment; and it is easy to become brittle and toughness decreases in a low temperature environment, so shortening its temperature. service life and limits the scope of use of this material

[0003] At present, there are not many waterproof plastic coils on the market that have good thermal insulation and sound insulation effects, good stability, and can be used in lower temperature environments.
