Problems solved by technology

[0003] At present, the existing composite materials have poor natural degradability and are not easy to degrade in the environment. If they cannot be effectively treated after a large amount of use, a large amount of white pollution will be generated, which will affect the life activities of animals and microorganisms in nature.

Embodiment example 1

[0051] Weigh 90 parts of microcrystalline starch, 80 parts of sodium hydroxide solution, 50 parts of triruthenium dodecacarbonyl, 60 parts of depolyhydroxybutyrate, 45 parts of chitosan and 20 parts of silane coupling agent, send the microcrystalline starch to Put it into the mixing tank, feed carbon dioxide and fumigate for 20 minutes, then add the fumigated microcrystalline starch into the ultrasonic emulsification disperser, add sodium hydroxide solution, and carry out ultrasonic dispersion treatment. After treatment, the ultrasonic dispersion treatment mixed solution is obtained. Sieve the ultrasonic dispersion treatment mixed solution to remove large particle precipitation, put triruthenium dodecacarbonyl and polyhydroxybutyrate into the sieved ultrasonic dispersion treatment mixed solution, put it into a magnetic stirrer, stir magnetically for 20 minutes, and pump Filter, dry the product after suction filtration at 135°C for 3h, send it into a muffle furnace, calcinate at...

Abstract

The invention relates to the technical field of composite materials, in particular to a degradable material and a preparation method thereof. The degradable material comprises polylactic acid, modified bamboo fibers, modified starch, polyethylene, a surfactant, an anti-ultraviolet agent, a plasticizer, an antioxidant and a stabilizer. The degradable material specifically comprises in parts by weight: 100 to 150 parts of polylactic acid, 80 to 110 parts of modified bamboo fiber, 70 to 100 parts of modified starch, 20 to 40 parts of polyethylene, 5 to 10 parts of the surfactant, 15 to 20 parts of a light degradation agent, 8 to 12 parts of the anti-ultraviolet agent, 2 to 7 parts of the plasticizer, 3 to 7 parts of the antioxidant and 1 to 6 parts of the stabilizer. The degradable material provided by the invention can effectively solve the problems that existing composite materials are poor in natural degradability, hard to degrade in an environment, and will cause generation of a large amount of white pollution and influence on life activities of animals and microorganisms in the nature if cannot be effectively degraded.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a degradable material and a preparation method thereof. Background technique [0002] While human beings create modern civilization, it also brings negative impacts. Disposable tableware, disposable plastic products, and agricultural mulch are difficult to recycle. The main treatment methods are incineration and burial. Incineration will produce a lot of harmful gases. Pollution of the environment; burying the polymer in it cannot be degraded by microorganisms in a short period of time, and also pollutes the environment. The residual plastic film exists in the soil, which hinders the development of the root system of crops and the absorption of water and nutrients, reduces the air permeability of the soil, and leads to the loss of crops. production reduction; animals will die after eating the discarded plastic film due to intestinal obstruction; synthetic fiber fishin...
