Problems solved by technology

Since there is no anti-aging agent, the service life is only 3-6 months, the thermal insulation performance is not high, the air permeability is poor, the service life is short, and the expected purpose of promoting crop growth and high yield cannot be achieved.

Embodiment 1

[0016] The functional agricultural cloth is prepared by 98% of polypropylene, 21.2% of anti-aging agent TL-F900, and 0.8% of TL-F3009 or TL-F2328 masterbatch.

[0017] Masterbatch quality standard:

[0018] Appearance: smooth surface, uniform particles, no impurities, diameter: 3×3mm, specific gravity 0.92-1.7g, moisture content: 0.12-0.32%, melting index: MI=30-55, and heat temperature: 210°C, volatile Temperature: 300°C, decomposition degree of additives: 6.2.

Embodiment 2

[0020] The functional agricultural cloth is prepared by 96.5% of polypropylene, 2.3% of TL-F9002 anti-aging agent, and 1.2% of TL-F3009 or TL-F2328 masterbatch.

Embodiment 3

[0022] The functional agricultural cloth is formulated by 97.5% of polypropylene, 1.8% of TL-F9002 anti-aging agent, and 0.7% of TL-F3009 or TL-F2328 masterbatch.

Abstract

The invention provides a functional agricultural cloth prepared from 96-98.3% of polypropylene, 1-2.5% of an aging resistor, and 0.7-1.5% of a color master batch. The manufacture method comprises the steps that 96-98.3% of polypropylene, 1-2.5% of an aging resistor, and 0.7-1.5% of a TL-F3009 or TL-F2328 color master batch are taken and mixed uniformly and then the mixture enters a screw melted extrusion machine; when the mixed raw materials are heated to the temperature of 210-235 DEG C suitable for spinning, the melt thereof is extruded by a screw and jetted out uniformly via groups of rectangular spinneret plates, wherein the number of holes of each spinneret plate is not greater than 500. The rotation speed of a metering pump is 35-40g / m<2>, and 25-29rpm is used for the agricultural cloth. The jetted filaments are cooled by air; the side blowing pressure of a compressor is 10-25Par. A spinning drafting system and a web former form an angle of 18-20 degrees. The functional agricultural cloth is good in anti-ageing performance, good in heat preservation and breathability and long in service lifetime (outdoor service lifetime being 2-3 years) and is in favor of crop growth and yield increase. An anti-counterfeiting mark is integrated to the functional agricultural cloth, so that the anti-counterfeiting effect is good.

Description

technical field [0001] The present invention relates to an agricultural cloth, in particular to a functional agricultural cloth with the number of spinneret holes ≤ 500 and the number of single filaments between 5.5dtex and 6dtex, which is integrally formed with a logo and its production method. Background technique [0002] In order to achieve the temperature and humidity required by crops, promote crop growth and early sowing, high yield, and stable yield, many farmers use polypropylene filament non-woven fabrics in the crop cultivation process. The spinneret of this kind of non-woven fabric manufacturing equipment has more than 750 holes in the spinneret, and the fineness of the single filament is between 2.5dex and 4.5dex. There is no vertical angle between the spinning drafting system and the web forming machine. Because there is no anti-aging agent, the service life is only 3-6 months, the thermal insulation performance is not high, the air permeability is poor, the ...
