Easy-to-degrade foamed material and preparation method thereof

Abstract

The invention discloses an easy-to-degrade foamed material. The easy-to-degrade foamed material is prepared from the following materials in parts by weight: 20 to 50 parts of cassava starch, 8 to 15 parts of sodium silicate alginate, 10 to 20 parts of rosin, 30 to 50 parts of rice straw, 50 to 100 parts of corn cob, 8 to 15 parts of bentonite, 15 to 25 parts of seaweed powder, 3 to 8 parts of tangerine peel powder, 20 to 50 parts of rice bran, 1 to 2 parts of nano zinc oxide and 3 to 8 parts of auxiliary. The auxiliary is prepared from the following materials in parts by weight: 3 to 8 parts of sodium dodecyl benzene sulfonate, 3 to 5 parts of ethanol and 3 to 10 parts of ethyl acetate. According to the easy-to-degrade foamed material, the corn cob, the rice straw and the rice bran are adopted as main raw materials for the foamed material, are crushed into powder, then are treated through alkaline water, and can form a cross-linked structure together with the cassava starch, the rosin and the bentonite; the foamed material is enabled to have obvious tensile strength and water resistance; meanwhile, the materials used by the easy-to-degrade foamed material are easily degraded; the price cost is low.

Description

technical field [0001] The invention relates to the field of foaming materials, in particular to an easily degradable foaming material and a preparation method thereof. Background technique [0002] Foam packaging materials are widely used in people's production and life. Traditional cushioning packaging materials are mainly made of general-purpose plastics such as polystyrene (PS) and polyethylene (PE). On the one hand, these general-purpose plastic foam materials consume limited oil resources, and on the other hand pollute the environment. Commonly used foam packaging waste treatment methods mainly include recycling, landfill and incineration. Among them, less than 1% of waste foam packaging materials are used for recycling; disposal by burial will occupy land resources and pollute the soil environment; disposal by incineration will pollute the atmospheric environment. Existing foam materials generally use difficult-to-degrade plastics, rubber, resin, etc. as base materi...

AI Technical Summary

Problems solved by technology

Among them, less than 1% of waste foam packaging materials are used for recycling; disposal by landfill method will occupy land resources and pollute the soil environment; disposal by incineration method will pollute the atmospheric environment

Existing foam materials generally use hard-to-degrade plastics, rubber, resins, etc. as base materials, and a large number of discarded non-degradable foam materials bring serious pollution to the environment

At present, starch is used as the main material of foaming materials, although it is easy to degrade, but the cost is high
