Wood-grain-imitating master batch applicable to PVC (Polyvinyl Chloride) and preparation method thereof

Abstract

The invention provides wood-grain-imitating master batch applicable to PVC (Polyvinyl Chloride) and a preparation method thereof. The wood-grain-imitating master batch is prepared from the following raw materials in percentage by weight: 20 to 60 percent of a background color component, 30 to 60 percent of a wood grain component, 5 to 25 percent of compound higher molecular weight wax, 1 to 5 percent of an antioxidant, 0.5 to 1 percent of a thermal stabilizer and 0.1 to 0.5 percent of a lubricant; the background color component is prepared from the following components in percentage by weight:0.1 to 5 percent of background color pigment powder and 95 to 99.5 percent of the PVC; the wood grain component is prepared from the following components in percentage by weight: 0.1 to 5 percent ofwood grain pigment powder, 30 to 60 percent of the PVC and 40 to 70 percent of PET (Polyethylene Terephthalate); the compound higher molecular weight wax is prepared from the following components in percentage by weight: 30 to 70 percent of modified polytetrafluoroethylene micro-powder wax and 30 to 70 percent of oxidized polyethylene wax. According to the wood-grain-imitating master batch provided by the invention, the compound higher molecular weight wax is added; the wear resistance of PVC plastic is enhanced under the synergistic effect of the modified polytetrafluoroethylene micro-powderwax and the oxidized polyethylene wax and the utilization performance of the plastic is improved.

Description

Technical field [0001] The invention relates to the field of color masterbatch, in particular to a wood-like grain masterbatch suitable for PVC and a preparation method thereof. Background technique [0002] In order to give plastics a good appearance, pigments are usually added in the plastic processing and shaping process. If the pigments are used directly, the pigments will absorb water and oxidize due to direct contact with the air during storage and use. The pigment is generally in powder form, which is easy to fly when added and mixed, and it will affect the health of the operator after being inhaled by the human body. After the color masterbatch is made, the resin carrier isolates the pigment from air and moisture, which can keep the quality of the pigment unchanged for a long time. Color masterbatch is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resin. The selected resin has a good wetting and dispersing eff...
