Problems solved by technology

This kind of grass mat has the defects of low mechanical strength, heavy weight, and poor thermal insulation performance; and it is difficult to carry during use, which is not conducive to storage
Moreover, grass mats are prone to mildew after being subjected to rain, snow and wind, which not only affects the service life, but also increases diseases in vegetable planting and reduces the heat preservation effect.

Embodiment Construction

[0025] The production method, structure and application principle of the solar greenhouse waterproof and thermal insulation quilt provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] As shown in FIG. 1 , it is a schematic structural view of the solar greenhouse waterproof and thermal insulation quilt provided by the present invention. The solar greenhouse waterproof and thermal insulation is composed of an upper thermal insulation layer, a lower thermal insulation layer and an air barrier layer 6 sandwiched by an ultra-thin PE plastic film with a thickness of 0.01-0.1 mm. Among them, the upper insulation layer consists of a PE waterproof film layer 5 with a thickness of 0.2-0.5 mm, a non-woven fabric layer 4 with aesthetics and wear resistance, upper and lower felt sheets 1, 2 and polyester woven fabrics sandwiched by the felt sheets. The reinforcing rib layer 3 formed; the lower insulation layer is...

Abstract

The invention discloses a waterproof thermal insulated quilt used in light greenhouse booth, belonging to greenhouse booth thermal insulated technique. The invention is characterized in that preparing felt layer, preparing upper and lower thermal insulated layers and fixing the upper and lower thermal insulated layers to obtain a light greenhouse waterproof thermal insulated quilt formed by a waterproof membrane layer, a non-woven cloth layer, upper and lower felt sheets with a strength bar layer between, an air insulated layer, a lower felt sheet, a strength bar layer, an upper felt sheet, and a non-woven cloth layer. The invention can insulate water, seal and confirm transparence, and improve thermal insulation, with low cost, low weight, corrosion resistance, non-pollution and recycle property.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for greenhouses, and in particular relates to a thermal insulation quilt for solar greenhouses and a production process thereof. Background technique [0002] At present, the solar greenhouse for producing vegetables has been promoted in a large area, and the thermal insulation material used in the solar greenhouse has been the grass felt made of straw for many years. This grass mat has the defects of low mechanical strength, heavy weight, and poor thermal insulation performance; and it is difficult to carry during use, which is not conducive to preservation. Moreover, grass mats are prone to mildew after being subjected to rain, snow and wind, which not only affects the service life, but also increases diseases in the vegetable planting industry and reduces the heat preservation effect. Contents of the invention [0003] The ...
