Greenhouse heat preservation quilt

Abstract

The invention provides a greenhouse heat preservation quilt which comprises a rainproof layer, a heat-preserving layer and an infrared blocking layer. The rainproof layer is composed of a cloth layer and a resin layer fixedly connected with the cloth layer, the heat-preserving layer is composed of bubble film layers, the infrared blocking layer is a resin layer, an infrared blocking agent is additionally arranged in the infrared blocking layer, the resin layer in the rainproof layer is an anti-aging resin layer with ultraviolet absorbent inside, the infrared blocking agent is polyvinyl butyral, the heat-preserving layer is made of 2-8 layers of the bubble film layers, and polyethylene plastic cloth layers are arranged between the bubble film layers. The greenhouse heat preservation quilt has the advantages of being simple in structure, improving the heat-preserving effect of a greenhouse, being resistant to rain and snow and capable of timely cleaning rain and snow on the heat preservation quilt timely, reducing load of the greenhouse, being low in manufacturing cost and high in temperature regulating speed, guaranteeing growth and development of animals and plants in the greenhouse and the like, and a newly covered heat preservation quilt can raise the temperature in the greenhouse in a day.

Description

technical field [0001] The invention belongs to agricultural off-season planting tools, in particular to a greenhouse heat preservation quilt. Background technique [0002] At present, my country has widely promoted the planting technology of greenhouse vegetables. Covering the ground with plastic greenhouses can increase the temperature of the soil and the environment near the surface, keep the moisture in the soil, maintain the humidity of the environment near the surface, and reduce the impact of seasons and disastrous weather on crops. In order to improve the insulation effect of plastic greenhouses, people will cover the outside of plastic greenhouses with thermal insulation quilts. At present, most of the thermal insulation curtains used are insulation materials made of straw and straw to cover the top of plastic greenhouses. This kind of thermal insulation curtain has certain disadvantages, such as heavy weight, which requires a strong greenhouse frame and strong pre...

AI Technical Summary

Problems solved by technology

This kind of thermal insulation curtain has certain disadvantages, such as heavy weight, which requires a strong greenhouse frame and strong pressure resistance, which increases the production cost of the greenhouse; it is perishable, has a short service life, poor thermal insulation effect, and is not rain-proof; The speed is slow, and the newly covered thermal insulation curtain cannot raise the temperature in the shed within a week, which will affect the growth and development of animals and plants in the shed

Although the use of felt as insulation can improve the insulation effect of the greenhouse and reduce the weight of the greenhouse, but the felt is easily damaged and needs to be replaced frequently, which increases the cost of using the greenhouse
