High-diffuse-reflection brightness enhancement coating for inner wall of greenhouse

Abstract

The invention discloses a greenhouse interior wall high diffuse reflection brightness enhancement coating, which comprises the following raw materials: titanium dioxide, zirconium dioxide, paint and apaint diluent, wherein the weight ratio of titanium dioxide, zirconium dioxide, paint and the paint diluent is (67-87):(13-33):(350-450):(20-40). The invention relates to the technical field of greenhouse light enhancement. The invention relates to a coating, in particular to a coating with high diffuse reflection to visible light and near infrared rays. The reflectivity can reach 85-90% and thereflected light rays are irregularly reflected towards different directions, so that different parts of crops can receive sunlight from different directions, and the sunlight is fully utilized, the potential that many parts of the crops difficultly receive the sunlight is brought into play, and the high-diffuse-reflection brightness enhancement coating is very beneficial to growth, development, blooming, fruiting and quality of the crops.

Description

technical field [0001] The invention relates to the technical field of greenhouse light enhancement, in particular to a high diffuse reflection light enhancement coating on the inner wall of a greenhouse. Background technique [0002] In winter, the greenhouse is planted out of season, and the days are short and the nights are long. In order to keep warm, the insulation quilt is always lifted late and covered early, resulting in a serious lack of light for the crops. Because the photosynthesis of greenhouse crops comes from direct sunlight, and the crop leaves The middle and lower parts of crops often cannot receive light, which affects photosynthesis and affects growth. The north wall and the east and west walls of the greenhouse are generally made of loess or red bricks. The reflectivity of the surface to sunlight is about 15% to 20%, and most of the sunlight shining on it is absorbed. Even if the existing technology increases the use of aluminum film reflective curtains ...

Problems solved by technology

The existing technology adopts the greenhouse light supplement device, and various fluorescent lamps, LED lamps, high-pressure sodium lamps, etc. can be said to be insignificant compared with the luminous intensity of sunlight. The off-season planting in the greenhouse seriously affects the growth and development of crops due to the above-mentioned reasons. , output, quality
