Ordinary plastic film is used in crab breeding. Due to its low strength, it is easy to be cut by the fingertips of the crab when it escapes and climbs, and it is easily torn by the bite of dogs, cats, mice and other animals.
In addition, plastic films used in agriculture and aquaculture are prone to aging and deterioration due to exposure to the sun and rain for a long time, and they must be replaced at least two to three times a year, which not only increases production costs, wastes manpower and material resources, but also causes environmental pollution

Abstract
The invention provides a plastic membrane for preventing cultured crabs escaping and a preparation method thereof. The plastic membrane comprises the components with the following weight portions: 70 to 90 portions of polyolefin base material, 2.5 to 3.5 portions of antioxidant 2, 6 di-butyl-p-cresol, 0.01 to 0.03 portions of isocyanuric three(3,3- di-butyl-4-hydroxy benzyl) ester, 5 to 10 portions of reinforcing agent nano-montmorilonite and 15 to 20 portions of the mixture of terpineol / rough dipentene with the weight ratio of 50:50. The polyolefin base material is preferably 55 to 65 weight portions of liner low density polyethylene and 15 to 25 weight portions of low density polyethylene. As the improvement of the invention, the raw material of the plastic membrane also comprises 10 to 25 weight portions of metallocene catalyst for liner low density polyethylene. With the invention, the plastic membrane has good aging inhibiting effect and better solves the problem that the plastic membrane is easy to age and deteriorate due to sun burning and watering outside for a long time.
Description
technical field [0001] The invention relates to a plastic film for preventing cultured crabs from escaping and a preparation method thereof. Background technique [0002] For the breeding technology of famous, special and high-quality aquatic products, there are certain rules for crabs to escape. Mastering the law and taking corresponding preventive measures can effectively control the escape of crabs. In the 1980s, the method of building high mud ridges was adopted to prevent crabs from escaping. In the 1990s, there were generally three types of fences: cement brick walls, calcium-plastic board fences, and polyethylene mesh fences. The above several forms are either not effective in preventing escape or the cost of preventing escape facilities is too high. And common plastic film is used in crab breeding, because intensity is low, is easily cut off by its fingertip when crab escapes climbing and is bitten and torn by animals such as dog, cat, mouse. In addition, the plas...
