Agricultural degradable stone paper and preparation method thereof

Abstract

The invention provides agricultural degradable stone paper and a preparation method thereof. The agricultural degradable stone paper comprises the following components in parts by weight: 1-3 parts of rutile titanium pigment, 1-3 parts of anatase titanium pigment, 45-65 parts of heavy calcium carbonate, 10-30 parts of light calcium carbonate, 3-5 parts of silane coupling agent, 15-25 parts of low density polyethylene, 5-10 parts of hot melt adhesive, 1-3 parts of bentonite and 0.5-1 part of sorbitam stearate. The agricultural degradable stone paper provided by the invention takes high molecular polymers as substrate raw materials; and by utilizing sunshine and steam of the farmland, the stone paper can be rapidly degraded in certain time after the stone paper achieves the effects of water retention, heat preservation and pregermination through the recombination action of light and water. The agricultural degradable stone paper provided by the invention has the advantages of saving labor cost and protecting land resources; and the agricultural degradable stone paper has a very good meaning in improving the environment of the farmland, especially the farmlands in mountain areas, remote areas and areas lacking water resources.

Description

technical field [0001] The present invention relates to an agricultural material. Background technique [0002] China is a large agricultural country. In the process of crop growth, water retention and heat preservation and accelerated seed germination are a core link to ensure high-quality and high-yield agricultural production. For decades, plastics such as polyethylene or polyvinyl chloride have been used in agricultural water retention and heat preservation and accelerated seed germination processes. As thermal insulation materials, these plastic films have played a huge role in improving the quality and output of agricultural products, and have been widely and maturely used. Especially, there are more and more varieties of degradable plastic films in farmland, and they have also achieved very good results. Effect. Although plastic films such as polyethylene or polyvinyl chloride have excellent water retention and germination effects, due to the long degradation period ...

AI Technical Summary

Problems solved by technology

Although plastic films such as polyethylene or polyvinyl chloride have excellent water retention and germination effects, due to the long degradation period in the field and the incomplete degradation effect, the film residues must be cleaned in the field. Especially in the late stage of seed germination, after the seedlings break through the soil, the residual film covering the ground surface must be removed in time so as not to affect the growth of the seedlings, and the labor cost is relatively high
