Embodiment Construction

[0022] An environment-friendly agricultural paper base film with high water resistance, which is composed of the following raw materials in parts by weight: 50 parts of industrial waste paper, 17 parts of water-soluble polyvinyl alcohol fiber, 12 parts of dry corn starch, appropriate amount of sodium hydroxide, ethanol 8 parts of solution, 5 parts of monochloroacetic acid, appropriate amount of 85% ethanol aqueous solution, appropriate amount of glacial acetic acid, 3 parts of polyethyleneimine, 45 parts of alkaline solution, 4 parts of epichlorohydrin, and 3 parts of polyamide epichlorohydrin resin , appropriate amount of water, 0.6 parts of deinking agent, 2 parts of hydrogen peroxide, 1.5 parts of sodium silicate, and 4 parts of paraffin.

[0023] Specific steps are as follows:

[0024] (1) Preparation of alkalized starch:

[0025] Accurately weigh the dry base corn starch, fully mix it with sodium hydroxide in a mixer, then transfer it to a dry reaction kettle, and alkali...

Abstract

The invention discloses an environment-friendly agricultural paper-based mulching film with high water resistance. The environment-friendly agricultural paper-based mulching film with high water resistance comprises the following raw materials in parts by weight: 40-55 parts of industrial waste paper, 13-21 parts of water-soluble polyvinyl alcohol fibers, 8-16 parts of dry corn starch, proper amount of sodium hydroxide, 3-10 parts of ethyl alcohol solution, 2-7 parts of chloroacetic acid, proper amount of 85% of ethanol aqueous solution, proper amount of glacial acetic acid, 2-6 parts of polyethyleneimine, 36-62 parts of alkaline solution, 2-7 parts of epichlorohydrin, 1-5 parts of polyamine epichlorohydrin resin, proper amount of water, 0.2-0.9 part of a deinking agent, 1-3 parts of hydrogen peroxide, 0.8-2 parts of sodium silicate, and 2-6 parts of paraffin. According to the environment-friendly agricultural paper-based mulching film with high water resistance, epichlorohydrin is used as a crosslinking agent for promoting the crosslinking reaction in molecules and between molecules of carboxymethyl starch and polyethyleneimine, thus forming a complete crosslinking system; the industrial waste paper is used as the raw material, and the prepared paper-based mulching film is high in water resistance.

Description

technical field [0001] The invention relates to a soil covering film, in particular to an environment-friendly agricultural paper base film with high water resistance and a preparation method thereof. technical background [0002] Film mulching is a new agricultural technology that is suitable for my country's national conditions, has wide adaptability, and is widely used to promote early maturity, high yield, and high efficiency of cover crops. Plastic film can maintain soil moisture and increase soil temperature, etc. After covering with plastic film, it can improve the temperature and moisture status of the soil and near the ground. At present, plastic film covering technology has been applied to wheat, rice, corn, soybean, sorghum, cotton, watermelon In the planting of other crops, the effect of increasing yield is obvious. [0003] However, since the mulch film used in large quantities is a non-degradable polymer compound, it is neither eroded by microorganisms nor dec...
