Problems solved by technology

However, at present, the transparent PVC profiles and sheets produced by most manufacturers are not good at low temperature brittleness, and the low temperature drop hammer impact is often not good enough, especially in the process of using in winter, it is easier to crack
At the same time, due to the addition of plasticizers, surface fogging is prone to occur during use, and this phenomenon will become more serious as the amount of plasticizers increases.
The transparent PVC products produced by the prior art limit the use environment and application range

Abstract

The invention discloses a high-impact-strength transparent PVC/MBS alloy material and a preparation method thereof. The alloy material comprises, by mass, 100 parts of PVC resin, 50-120 parts of MBS resin, 4.0-6.0 parts of stabilizer, 4.0-8.0 parts of impact modifier, 3.0-5.0 parts of processing auxiliary, 1.0-3.0 parts of weather-resistant agent and 5.0-25.0 parts of inorganic filler. Being mixed evenly according to a certain process by means of a high cooling mixing unit, the raw materials are extruded through a conical dual-screw extruder and granulated. The formula is further optimized, impact resistance of PVC is greatly improved, and transparency is also improved. The situation that a plasticizer is used in the prior art for changing the plasticity of PVC is abandoned, MBS and PVC are mixed to adjust the plasticity of PVC, and the prepared PVC/MBS alloy material can be used in the aspect of transparent PVC profiles, sheets, PVC transparent environment-friendly hoses, transparent packages, daily stationery plastic and the like.

Description

technical field [0001] The invention relates to an alloy material and a preparation method thereof, in particular to a high-impact transparent PVC / MBS alloy material and a preparation method thereof. Background technique [0002] The main component of PVC co-extrusion materials used for transparent PVC profiles and sheets is polyvinyl chloride, and plasticizers, stabilizers, processing modifiers and other auxiliary materials are added to increase its heat resistance, toughness, processability, etc. PVC is a well-loved, popular and widely used synthetic material in the world today. PVC-U profiles and sheets are widely used as a new type of construction, electronics, and packaging materials. Due to their physical properties such as rigidity, elasticity, corrosion resistance, and excellent aging resistance, they are usually used as copper, zinc, aluminum, etc. Good substitute for non-ferrous metals. However, at present, the transparent PVC profiles and sheets produced by most...
