Abstract

The invention discloses a master batch with the functions of toughening, chemical corrosion resistance and color matching, and belongs to the technical field of modified plastics. The master batch is prepared from the following raw materials in parts by weight: 0-35 parts of polyolefin resin, 0-20 parts of PS resin, 0-15 parts of a compatilizer, 0-40 parts of a toughening agent, 0-20 parts of a reinforcing agent, 15-35 parts of pigments, 0.5-1 part of an antioxygen and 1-5 parts of a lubricant. The master batch can improve the toughness of an interlayer material and enables the elongation at break to be doubled or higher; by adopting the alloy technology, the dissolution of the interlayer HIPS by a foaming agent is reduced, cracks due to partial dissolution of the material is prevented; the master batch also enables sheet materials to have excellent covering power, and meets the trend of a thinner liner of a refrigerator; color matching can be carried out according to customer requirements.

Description

technical field [0001] The invention relates to a masterbatch with the functions of toughening, chemical corrosion resistance and color matching and a preparation method thereof, belonging to the technical field of modified plastics. Background technique [0002] With the gradual saturation and development of the home appliance market, the demand for refrigerators mainly comes from replacements and product upgrades. The overall high-end development is a major trend in the development of the refrigerator market. Large-capacity refrigerators are one of the products favored by customers, and large-capacity refrigerators Higher requirements are put forward for various technical indicators of products. When the conventional HIPS extruded sheet is used for plastic-absorbing refrigerator liners, especially for large-capacity refrigerators, cracking of the inner liner will occur during use, which seriously affects the use effect of customers. [0003] The main reasons for the crack...
