Problems solved by technology

[0002] Traditional plastic dust-proof nets are mainly made of non-degradable resins, such as PP, PE, PVC, etc. When used outdoors such as earthwork construction sites, they will be damaged by harsh environments such as sunlight, ultraviolet rays, high temperature, and high humidity. It will be weathered and turned into fragments, and then become plastic particles that penetrate into the soil and cause pollution. After the construction period is over, the dust-proof net is often discarded directly and not reused. A large amount of white garbage will seriously pollute the environment.

Embodiment

[0020] Such as figure 1 Shown, a fully biodegradable dust-proof net and preparation method thereof, said dust-proof net is made of the following components by weight: 8 parts of starch-based PLA, 62 parts of bio-based PBAT, 25 parts of calcium carbonate powder 5 parts, 5 parts of diacetyl epoxy vegetable oleic acid glycerides. The particle size of the calcium carbonate powder is 3000 mesh.

[0021] The preparation method of described dust-proof net comprises the steps:

[0022] S1. Add starch-based PLA, bio-based PBAT, calcium carbonate powder and diacetylepoxy vegetable olein into a high-speed mixer in parts by weight, and mix for 3 minutes at a speed of 200r / min;

[0023] S2. After releasing the uniformly mixed material, add it to a twin-screw extruder, extrude, pull, and cool to obtain special resin particles for modified high-content calcium carbonate;

[0024] S3, adding the modified high-content calcium carbonate special resin particles into the film blowing machine u...

Abstract

The invention discloses a completely biodegradable dustproof net and a preparation method thereof. The dustproof net is prepared from the following components in parts by weight: 3-10 parts of starch-based PLA (polylactic acid), 60-65 parts of bio-based PBAT (poly (butylene adipate-co-terephthalate)), 20-35 parts of calcium carbonate powder and 3-5 parts of diacetyl epoxy vegetable oil glyceride. Compared with a traditional plastic dust screen, the dust screen provided by the invention has excellent mechanical properties and water and heat resistance, and can be completely biodegraded to realize zero pollution.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a completely biodegradable dust-proof net and a preparation method thereof. Background technique [0002] Traditional plastic dust-proof nets are mainly made of non-degradable resins, such as PP, PE, PVC, etc. When used outdoors such as earthwork construction sites, they will be damaged by harsh environments such as sunlight, ultraviolet rays, high temperature, and high humidity. It will be weathered and turned into fragments, and then become plastic particles that penetrate into the soil and cause pollution. After the construction period is over, the dust-proof nets are often discarded directly and not reused. A large amount of white garbage will seriously pollute the environment. Contents of the invention [0003] To solve the above problems, the present invention provides a completely biodegradable dust-proof net and a preparation method thereof. [0004] The pres...
