Embodiment 1

[0022] A preparation method for antibacterial artificial turf, comprising the following steps:

[0023] A. Preparation of Antibacterial Coloring Masterbatch

[0024] 75 parts of carrier, 5 parts of antibacterial agent, 8 parts of coloring agent and 1 part of cyclopolydimethylsiloxane weighed according to the formula are fed in the order of first heavy and then light, and mixed in the mixer. After mixing for 3 minutes at normal temperature, the mixed material was transferred to a twin-screw extruder for melt extrusion. The screw speed of the extruder was 100r / min, and the feed speed was 25r / min; After cooling and granulating, it is packaged.

[0025] B. Weigh 60 parts of carrier, 20 parts of antibacterial coloring masterbatch in step A, 0.5 part of antioxidant, 1 part of ultraviolet absorber and 0.1 part of cyclopolydimethylsiloxane according to the formula, and put them into the mixer at normal temperature Mix for 30 minutes, add the mixture to the spinning screw extruder ...

Embodiment 2

[0029] A preparation method for antibacterial artificial turf, comprising the following steps:

[0030] A. Preparation of Antibacterial Coloring Masterbatch

[0031] 85 parts of carrier, 25 parts of antibacterial, 15 parts of coloring agent and 10 parts of cyclopolydimethylsiloxane weighed according to the formula are fed in the order of first heavy and then light, and mixed in a mixer, at room temperature After down mixing for 35min, the mixture was transferred to a twin-screw extruder for melt extrusion. The screw speed of the extruder was 150r / min, and the feed speed was 40r / min; , Packed after granulation.

Abstract

The invention discloses a preparation method of an antibacterial artificial turf. The method comprises the preparation of antibacterial and coloring master batch, the preparation of artificial fiber grass and the implementing of final forming process. Compared with a preparation method in the prior art, for the preparation method disclosed by the invention, the mixing time is long, and the strength of a finished product is high as a low-small-molecular-weight dispersing agent is added, the problem that the artificial turf is broken due to insufficient strength caused by local stress concentration is hard to occur; the antibacterial master batch and the coloring master batch are prepared together, so that the method disclosed by the invention is low in production cost and the mixing is relatively uniform.

Description

technical field [0001] The invention relates to an artificial turf, in particular to a method for preparing an antibacterial artificial turf. Background technique [0002] Artificial turf consists of 3 layers of material. The base layer is composed of rammed soil layer, crushed stone layer and asphalt or concrete layer. The base layer is required to be solid, non-deformable, smooth and impermeable, that is, the general concrete site. Due to the large area of ​​the hockey field, the base layer must be properly treated during construction to prevent subsidence. If the concrete layer is laid, expansion joints should be cut after the concrete is cured to prevent thermal expansion deformation and cracks. [0003] Above the base layer is a cushioning layer, usually rubber or foam. The rubber is moderately elastic, with a thickness of 3-5mm. The cost of using foam plastic is low, but the elasticity is poor, the thickness is 5-10mm, the lawn is too thick and too soft, and it is...
