Abstract

The invention discloses a rice transplanter plastic casing material. The rice transplanter plastic casing material is prepared from, by weight, 3-4 parts of carbon nano tubes, 40-50 parts of thionyl chloride, 3-5 parts of N,N-dimethyl formamide, 100-120 parts of ethidene diamine, 16-20 parts of melamine, 36-40 parts of 35%-37% formaldehyde aqueous solution, 170-200 parts of polyvinyl chloride, 30-40 parts of light calcium carbonate, 18-20 parts of phthalic acid ester, 20-30 parts of 75 wt%-80 wt% sulfuric acid and 30-40 parts of 95 wt%-98 wt% nitric acid. The modified carbon nano tubes, melamine and the formaldehyde aqueous solution are co-polymerized and synthesized into melamine resin, perssad on the surfaces of the modified carbon nano tubes can form hydrogen bonds with amino in the melamine resin and interacts with other polarities, and therefore heat-resisting stability of the composite is improved, and a promotion effect is achieved for improving the structure stability and strength of the finished product.

Description

technical field [0001] The invention relates to the technical field of rice transplanters, in particular to a plastic shell material for a rice transplanter and a preparation method thereof. Background technique [0002] Carbon nanotubes have excellent mechanical properties and self-lubricating properties. As a filling material, if they can be uniformly dispersed in the polyvinyl chloride matrix and can form good interfacial compatibility with the polyvinyl chloride matrix, they can be used effectively. Improve the mechanical properties and friction properties of polyvinyl chloride matrix. However, due to the large surface energy and specific surface area of ​​carbon nanotubes, carbon nanotubes are easy to aggregate; at the same time, the surface of carbon nanotubes presents a strong non-polarity, making it insoluble in any solvent and polymer. Therefore, in order to improve the dispersion of carbon nanotubes in the polymer matrix and enhance the interfacial compatibility b...
