Problems solved by technology

But the defect of existing imitation wood-grain masterbatch is: the carrier resin selected by imitation wood-grain masterbatch has poor compatibility with the base material to be colored, poor temperature resistance, large fluctuations in wood grain, and the prepared imitation wood Textured products are unstable
However, this method has high requirements on the temperature of the production workshop. If the workshop temperature is too low, it will make it difficult to input the color paste; the preparation of the color paste is troublesome and the wood grain of the imitation wood grain special-shaped material product is difficult to control, and large wood grain flowers will appear. problem, resulting in poor imitation wood grain effect
At present, there are few research reports on imitation wood grain color masterbatch for PVC-based imitation wood grain profiles

Embodiment 1~8 and comparative example 1~3

[0043] Examples 1~8 and Comparative Examples 1~3: Preparation of imitation wood grain masterbatch

[0044] Carry out high-speed mixing 600s in high-speed mixer with PVC resin, pigment, dispersing agent, other auxiliary agents in embodiment 1~8 and comparative example 1~3, adopt single-screw extruder to carry out melt blending after mixing the material, extrude The range of temperature control in the discharge temperature zone is 120-170°C, and the screw speed is 23RPM. The pigment is uniformly dispersed in the carrier resin through shearing and mixing of the screw, and then naturally cooled, pelletized, and air-dried to obtain the imitation powder of the present invention. Wood grain masterbatch.

[0045] The pigment red in the examples and comparative examples is selected as one or more mixtures of iron oxide red 101, iron oxide red 110, iron oxide red 130, iron oxide red 190, and pigment red 122.

Abstract

The invention discloses an imitation wood grain color masterbatch, which comprises, by weight percentage: 60-93% PVC resin; 1-18% pigment; 0.5-14% dispersant; 3-15% other additives. Its preparation method is as follows: a) adding each component into a high-speed mixer according to the proportion and mixing; b) using a single-screw extruder for the above-mentioned mixture at a screw speed of 14-27RPM and a melting temperature of 120-170°C Melt blending and extruding, the pigment is uniformly dispersed in the carrier resin by shearing and kneading of the screw, naturally cooled, pelletized, and air-dried to obtain the imitation wood grain color masterbatch; the imitation wood grain color masterbatch of the present invention It is easy to operate and control when used in the preparation of imitation wood grain wood-plastic composite materials, and the imitation wood grain color masterbatch has good compatibility with PVC-based base materials and has a high degree of The simulated solid wood appearance has natural and clear lines, the surface color is bright, and the effect of imitating wood grain is good. It is an ideal imitation wood-plastic product.

Description

technical field [0001] The invention relates to the field of coloring of wood-grain-like profiled materials, in particular to a wood-grain-like masterbatch, a preparation method thereof, and an application in wood-grain-like wood-plastic composite materials. Background technique [0002] As a new type of environmentally friendly material, imitation wood grain wood-plastic composite material has been widely used for its advantages of light weight, good touch, corrosion resistance, moisture resistance, insect resistance, and flame retardancy. But the defect of existing imitation wood-grain masterbatch is: the carrier resin selected by imitation wood-grain masterbatch has poor compatibility with the base material to be colored, poor temperature resistance, large fluctuations in wood grain, and the prepared imitation wood Texture products are unstable. [0003] Patent CN1386623 discloses that on the twin-screw plastic profile extruder production line, the imitation wood-grain p...
