Problems solved by technology

Most of the research on artificial turf at present focuses on the profile of artificial turf (such as USP 5462778, WO 2005 / 005731), weaving and paving methods (such as USP 4381805, USP6491991, USP 6815059, USP 6955841, WO 01 / 0161110, WO 2005 / 124028) and the design of performance testing instruments (such as USP 6854316, USP 6962073), etc., although the patent WO2006 / 066777 mentioned the formula and mechanical properties of artificial grass fiber materials, it did not involve the performance of grass color weather resistance and aging

Embodiment 1

[0027] Under normal temperature and pressure, the following components and percentages by weight: 45% linear low-density polyethylene (LLDPE), 5% low molecular weight polyethylene wax, 15% lithopone, 5% titanium dioxide, 3% phthalocyanine blue, azo Yellow pigment 15%, iron black 2%, phenolic antioxidant 264 2%, triazine light stabilizer 5%, titanate coupling agent 1%, liquid paraffin 2%, after batching, the pigment and plastic The polyethylene wax, phenolic antioxidant, triazine light stabilizer and linear low density polyethylene in the auxiliary agent were added to a high-speed mixer with a rotation speed of 1400 rpm and mixed for 15 minutes, and then added to titanate coupling The mixture of solvent and liquid paraffin, then mixed at a high speed for 15 minutes, and finally the above-mentioned mixed materials were sent to a twin-screw extruder at a temperature of 200°C, and the screw speed was 100r / min to extrude, cooled, dried, and pelletized Make the required masterbatch....

Embodiment 2

[0031] Under normal temperature and pressure, the following components and percentages by weight: low density polyethylene (LDPE) 32%, ethylene bis stearic acid amide (EBS) 5%, zinc stearate 1%, ultramarine 20%, inorganic yellow pigment 21%, carbon black 2%, hindered amine light stabilizer 8%, phosphite antioxidant 2%, silane coupling agent 5%, liquid paraffin 4%. Add EBS, phosphite antioxidant, hindered amine light stabilizer and low-density polyethylene into a high-speed mixer with a rotation speed of 1400 rpm and mix for 15 minutes, then add the mixture of titanate coupling agent and liquid paraffin , and then mix at high speed for 20 minutes, and finally send the above-mentioned mixed materials into a twin-screw extruder at a temperature of 180°C, and extrude at a screw speed of 150r / min. After cooling, drying, and pelletizing, the required masterbatches are made. .

Abstract

The invention relates to a technology of color master batches for a polyolefin yarn fiber, which comprises pigments, plastic additives and carrier resin, wherein the plastic additives comprise dispersed lubricant, an antioxidant, a light stabilizer, a coupling agent and liquid paraffin. The process for preparation is that the pigments, a part of plastic additives and the carrier resin are added into a high-speed mixer to be mixed, and then the coupling agent and the liquid paraffin are added to be stirred in a high speed, and at last the above stirred mixture is sent to a twin-screw extruder to be extruded, cooled, dried and granulated. The invention has the characteristics of less dosage, excellent weathering resistance, easy dispersing and excellent processability, and is suitable for the yarn fiber which takes polyethylene, polypropylene and other copolymer as base materials.

Description

technical field [0001] The invention relates to the coloring of artificial turf fibers, in particular to the preparation of color masterbatches for polyolefin grass fibers for artificial turf and a method thereof by using polyolefin resin as a main raw material. Background technique [0002] The development of artificial turf stems from the limitations of natural grass to changes in climatic conditions. With the technological innovation of artificial turf fiber, the mechanical properties, safety performance and comfort performance of artificial turf are gradually approaching that of natural grass, so the application range of artificial turf has gradually expanded to professional sports venues, and even FIFA (FIFA) proposed that it will The use of artificial turf in the 2010 World Cup in South Africa marks that the development of artificial turf will enter a new stage. [0003] Artificial turf fiber material is the core material of artificial turf, and its performance determ...
