Heat preservation cover for greenhouse

Abstract

The invention relates to a heat preservation cover for a greenhouse. The heat preservation cover comprises two covering layers, wherein two insulation layers are arranged between the two covering layers. Because the insulation layers are pearl wool insulation layers, the covering layer of one pearl wool insulation layer is an Oxford fabric covering layer, the covering layer of the other pearl wool insulation is a non-woven fabric covering layer, because an Oxford fabric has the advantages of light and thin textures, soft hand feel, good waterproof property, and good durability; a non-woven fabric has the advantages of moisture prevention, ventilation, flexibility, light textures and the like; and pearl wool has the advantages of water insulation, moisture prevention, heat preservation, good plasticity, strong flexibility, and the like, the whole heat preservation cover has the advantages of greatly reducing the weight, being good in effects of preventing wind, water and moisture, greatly enhancing the insulation property, being hard in damaging, and greatly prolonging the service life.

Description

technical field [0001] The invention relates to a thermal insulation covering layer for a greenhouse, in particular to a thermal insulation quilt for a greenhouse. Background technique [0002] In the north, due to the cold in winter, vegetables and other crops are generally planted in greenhouses. In order to increase the temperature in the greenhouse, it is usually necessary to cover the outside of the greenhouse with an insulation layer. At present, the traditional insulation covering materials used by farmers include grass thatch, Mats, paper quilts, quilts, etc., although these materials have a certain thermal insulation effect, they also have the following disadvantages: 1. They are heavy, and it takes a lot of work and effort to roll them; 2. The thermal insulation effect is poor and the wind resistance is low. It is not high, the waterproof performance is not good, and it is easy to be soaked by rain, snow or dew, which not only increases the weight, but also reduces...

They are heavy, and it takes a lot of work and effort to roll them; 2. The thermal insulation effect is poor and the wind resistance is low. It is not high, the waterproof performance is not good, and it is easy to be soaked by rain, snow or dew, which not only increases the weight, but also reduces the heat preservation performance. Collapse, bringing huge economic losses to users; 3. The service life is short, and it is easy to be damaged, deformed and rotted after being soaked by rain, snow, dew, etc.
