Airtight and waterproof type polypropylene film

Abstract

The invention provides an airtight and waterproof type polypropylene film. The polypropylene film is prepared from components in percentage by weight as follows: 25%-80% of polypropylene, 5%-40% of natural fiber, 10%-50% of calcium carbonate and 2%-6% of an adhesive, wherein the polypropylene can form a good and stable system and become a support component of the film in combination with the natural fiber, the calcium carbonate component is a good decomposition time regulating component, the degradation time is short in large addition amount and long in small addition amount, thus, the use amount of calcium carbonate can be regulated according to different use environments, and the adhesive can provide better toughness and increase the tear-resistant degree of the film.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an airtight and waterproof polypropylene film. Background technique [0002] Polypropylene film, also commonly known as non-woven fabric, is degradable and has a wide range of applications. However, due to the nature of its non-woven fabric, the film is easy to be filamentous and has gaps, which may cause water leakage during application. , easy to ventilate nature, resulting in limited application effect and range, for example, if it is applied on the environmental protection bag, it is easy to leak water, affecting the use effect, and there are few users, and if it is used on the mulch film, the mulch film will be breathable due to the gap If the phenomenon is too serious, the insulation effect will be greatly reduced. [0003] While taking advantage of the degradability of polypropylene film, the gaps obtained by traditional techniques also limit its application. Therefore, i...
