Problems solved by technology

However, the price of organic fluorine antifogging agents in Japan is extremely high, and the cost per ton of shed film has increased a lot, which limits the promotion and application of agricultural polyvinyl chloride shed films with antifog function; there are also organic boron surfactants used as antifogging agents and non-drip It is convenient for processing and application, but there is a problem of unsatisfactory anti-fog effect

Abstract

The invention relates to a transparent covering material for solar greenhouse in winter and for plastic greenhouse in early spring, in particular to a polyvinyl chloride antifogging dripless greenhouse film which can prevent from fogging in the greenhouse and enables the water drops in the condensed in the internal surface of the greenhouse film to wet and spread quickly. The polyvinyl chloride antifogging dripless greenhouse film adopts polyvinyl chloride resin as the base, adding plasticizer, heat stabilizer, ultraviolet absorbent, compound dripless agent and organosilicon antifogging agent into the polyvinyl chloride resin, and being prepared through calendering, stentering and other production process steps. The transparent covering material for solar greenhouse in winter and for plastic greenhouse in early spring has the advantages of good dripless antifogging effect, improvement of light transmittance for greenhouse film, incensement of light intensity, beneficial photosynthesis for crops, beneficial improvement of greenhouse temperature, acceleration of crops growth, and reduction of disease occurrence.

Description

technical field [0001] The invention relates to a transparent covering material for solar greenhouses in winter and greenhouses in early spring, in particular to a polyvinyl chloride anti-fog non-fogging material that can prevent the occurrence of fog in the greenhouse and enable the water droplets condensed on the inner surface of the greenhouse film to quickly wet and spread. Drop shed film. Background technique [0002] Plastic shed film has important properties such as light transmission and heat preservation, so it is widely used in agriculture. As a cover for winter greenhouse and early spring greenhouse vegetable production, it plays a very important role in solving the problem of difficulty in eating fresh vegetables in winter and spring in northern my country. effect. With the development of my country's agricultural science and technology, users have higher and higher functional requirements for PVC shed film, not only requiring low temperature resistance, anti-agi...
