Embodiment 1

[0032] A kind of ultra-insulation daylighting film or board for a greenhouse,

[0033] The film or plate includes a body, and the inside of the body is closed to form several independent cavities 4, and each cavity 4 is filled with nitrogen or inert gas to form an air bag; the body includes an upper wall 1, a lower wall 2 and several A reinforcing rib 3, the upper wall 1 and the lower wall 2 are connected by several reinforcing ribs 3 to form an integral structure, the cavity 4 is formed between any two adjacent reinforcing ribs 3, and the two ends of the opening of the cavity 4 are welded seal; the thickness of the upper wall 1 and the lower wall 2 is 18-20 μm;

[0034]When this embodiment is used, the upper wall 1, the lower wall 2, and the middle are air bags. Before the nitrogen is filled, the product itself has a certain heat preservation effect, and then nitrogen or other inert gases are used to fill the air bags. The inert gas has excellent heat insulation performance a...

Abstract

The invention belongs to the technical field of greenhouse insulation lighting and relates to a super insulation lighting film or board for a greenhouse and a production process of the lighting film or board. The film or board comprises a body, wherein the interior of the body is closed to form a plurality of independent cavities; and each cavity is filled with nitrogen or inert gases to form an airbag. The production process mainly comprises the following steps: extruder heating, raw material stirring and feeding, raw material extrusion, setting, pulling, annealing, secondary pulling, metering, cutting and rolling. In the raw material stirring and feeding step, the raw materials comprise PE, PP, POE (Polyolefin Elastomer), mPE, EVA (Ethylene-Vinyl Acetate) and an anti-aging agent; and inthe raw material extrusion step, nitrogen or inert gas filling and solder seal is performed while extruding the raw materials. The greenhouse film is free in water drop, slow in nighttime heat dissipation and excellent in insulation effect.

Description

technical field [0001] The invention relates to vegetable solar greenhouses, multi-span greenhouses, vegetable cold sheds, flower planting greenhouses, seedling-raising greenhouses, ecological gardens, breeding greenhouses and places required for lighting and heat preservation, and belongs to the technical field of heat preservation and lighting for greenhouses. More specifically, The invention relates to a super heat-retaining daylighting film or board for a greenhouse and a production process thereof. Background technique [0002] At present, in the production process of vegetable planting, poultry and livestock breeding and other temperature sheds, the lighting shed film used is very thin, which is easy to generate fog droplets. Although there is a drip shed film, the use time is short, and generally it will not exceed 12 months. Fog droplets are generated, and the longevity film generally has a lifespan of 3 years, and the shed film also dissipates heat quickly at night,...
