Problems solved by technology

Among them, the "grass square grid" was successfully used on the Baolan Railway, but due to many problems such as raw materials, transportation, construction, and service life, the cost of use was high, and standardized production and installation could not be achieved. It has become unsustainable
The existing plastic "warp knitted net" and "sunshade net" are also used as substitutes for "grass grid" to prevent and fix sand. However, these existing plastic nets have serious problems such as non-degradability and environmental pollution. Defects, it is easy to cause secondary pollution in desert areas

preparation example Construction

[0109] In the fourth aspect, in some embodiments, a method for preparing a sand-proof net is provided, the sand-proof net is the above-mentioned sand-proof net, and the preparation method includes:

[0110] mixing the second polylactic acid resin, antioxidant and optional additives, and making anti-aging concentrated masterbatch;

[0111] Mixing the anti-aging concentrated masterbatch and the first polylactic acid resin in proportion to obtain a monofilament;

[0112] The monofilament is woven into the sand-proof net.

[0113] It can be seen that the method is simple to operate, easy to realize, and easy to realize enlarged production.

[0114] Specifically, in some embodiments, the preparation method includes the following steps:

[0115] (1) mixing, stirring, melt-extruding and granulating the second polylactic acid resin, antioxidant and optional auxiliary agent in proportion to make anti-aging concentrated masterbatch;

[0116] (2) drying, mixing, stirring and drying th...

Embodiment 1

[0136] A biodegradable anti-sand net, the upper net uses honeycomb tissue with an opening ratio of 65%, and the lower net adopts plain weave with an opening ratio of 60%.

[0137] Mix 65 parts by weight of PLA, 20 parts of antioxidant 1010, 5 parts of DLTP, 5 parts of colorant and brightener in proportion to make an anti-aging concentrated masterbatch, and then concentrate 2% of anti-aging Masterbatch and 98% PLA are mixed to make PLA monofilament.

Embodiment 2

[0139] A biodegradable anti-sand net, the upper net uses honeycomb tissue with an opening ratio of 70%, and the lower net adopts plain weave with an opening ratio of 65%.

[0140] 86 parts by weight of PLA, 5 parts of antioxidant 1010, 5 parts of antioxidant 264, 4% of the coloring agent are mixed in proportion to make anti-aging concentrated masterbatch, and then 10% of anti-aging Concentrated masterbatch and 90% PLA are mixed to make PLA monofilament.

Abstract

The invention provides a protective material, application of the protective material, a sand prevention net, a preparation method of the sand prevention net, and a sand prevention device, belonging tothe technical field of sand prevention and control. The protective material is prepared from the following components in percentage by weight: 85 to 98% of first polylactic acid resin and 2 to 15% ofanti-aging concentrated master batch, wherein the anti-aging concentrated master batch comprises second polylactic acid resin, an antioxidant and an optional auxiliary agent. The sand prevention netcan be completely degraded within a certain period of time and has good sand prevention and prevention effects.

Description

technical field [0001] The invention relates to the technical field of sand prevention and control, in particular to a protective material and application thereof, a sand prevention net and a preparation method thereof, and a sand prevention device. Background technique [0002] Land desertification and desertification are one of the most serious ecological problems currently facing our country. With the needs of economic development, resource development and military industry, it is necessary to build railways, roads, mines, satellite launch sites, and various living buildings in the desert. and facilities, and if the raging sandstorm is not blocked and fixed, it will bury railways, highways and buildings, seriously affecting production and living safety. [0003] In the prior art, the sand prevention and sand fixation products used include "grass grid" and "plastic net". Among them, the "grass square grid" was successfully used on the Baolan Railway, but due to many probl...
