Problems solved by technology

The cooling agent utilizes the water resistance, film-forming adhesion of styrene propylene ester copolymer, and the reflective effect of calcium carbonate; shading and cooling, the cooling effect is poor
[0005] In order to prevent the above-mentioned traditional cooling agents from remaining on the shed film in winter and affecting daylighting due to the lack of time to fall off, it is usually required that the adhesion firmness is poor, and the adhesion life is about 1 to 2 months in sunny days; but after wind and rain, especially After the long-term impact of water droplets or water columns, the adhesion life is even worse. The rigid cooling agent and the flexible shed film with low surface energy are easily peeled off under the repeated impact of water and wind, that is, "re-spray after heavy rain" occurs. Condition
Moreover, after peeling off, the rigid cooling agent falls off the surface of the greenhouse film in the form of flakes or debris, exposing the mottled hydrophobic greenhouse film. In addition, different parts of the greenhouse film have different inclination angles, resulting in different peeling speeds, uneven lighting, and affecting agriculture. Production

Embodiment 1

[0145] This example is a hydrophilic cooling agent, which forms (weight) of: 2000 g of tackifier roster glyceryl, 8000 g of hydrophilic binder mica powder.

[0146] The preparation method of the above hydrophilic cooling agent is to heat the 2000G tackifier rosin glyceride, melt, mix well with 8000 g of hydrophilic material mica powder, and let it cool.

[0147] The hydrophilic cooling agent of the present embodiment is solid. When used, dissolved with 8000 g of solvent banana water, shake well, coated on the outer surface of the shed film, and then formed, formed a hydrophilic cooling agent layer. The first contact angle of the hydrophilic cooling agent layer and the water was measured = 19 °.

Embodiment 2

[0149] In this embodiment, a hydrophilic cooling agent is comprised of a plasticizer of 2500 g of a tackifier, 200 g to dissolve the tackifier, 6800 g of hydrophilic base, 100 g photocatalyst, 200g reversible Membrane, 30G crosslinking inhibitor, 100G crosslinking accelerator, 300g emulsifier, 40 g of sterilizing algae agent, 30 g of colorant, 50 g of infrared light reflective material, 10g photoluminescent material, 50g reversible thermochromic material, 1500g organic Solvent, 15000 g of water, 10g defoamer. Among them, the tackifier is a terpene resin, and the plasticizer that can dissolve the tackifier is diisooctyl oxide, the hydrophilic base is diatomaceous earth, and the photocatalyst is anatase-type titanium dioxide, reversible crosslinking. The film forming agent is a polyvinyl alcohol-boric acid composite system, and the crosslinking inhibitor is acetic acid. The crosslinking promoter is acetate. The emulsifier is a nonylphenol polyoxyethylene ether. The sterilizing algor...

Embodiment 3

[0153] This example is a hydrophilic cooling agent, which composition (weight) is: 5000g tackifier pine, 25000 g of hydrophilic material hydrophilic silica sol (20% dry matter content, ie, water 20000g, containing hydrogen silica sol) Dry substance 5000g), 1000 g of water, 300 g of emulsifier nonylphenol polyoxyethylene ether.

[0154] The preparation method of the above hydrophilic cooling agent is: the 10000 g of water, 5000 g of tackifier, 300 g of emulsifier is heated and emulsified, drying cool, and then mixing with 25000 g of a hydrophilic silica sol.

[0155]The hydrophilic cooling agent of the present embodiment is an emulsion. When used, coated on the outer surface of the shed membrane, after drying, forming a hydrophilic cooling agent layer. Wash the emulsifier, then dry, measure the first contact angle of the hydrophilic cooling agent and the water = 44 °.

Abstract

The invention relates to a hydrophilic cooling agent and application thereof. The hydrophilic cooling agent comprises a tackifier and a hydrophilic base material, and the hydrophilic degree of the hydrophilic cooling agent reaches that a first contact angle between the hydrophilic cooling agent and water is less than or equal to 50 degrees. The hydrophilic cooling agent is good in cooling effect, long in service life when being attached to water and capable of being slowly eliminated through water participation.

Description

Technical field [0001] The present invention relates to the field of greenhouse greenhouse cooling techniques, and more particularly to a hydrophilic cooling agents and their applications. Background technique [0002] High temperature season, in order to prevent the temperature of the facility agricultural greenhouse, the temperature is too high in agricultural production, usually to coat the cooling agents on the surface of the greenhouse film, cool down the environment in the greenhouse; and in the low temperature season, for sufficient lighting, it is necessary to remove the surface of the greenhouse film The cooling agent. Therefore, the cooling agent needs to cool and easy to eliminate two features. [0003] The main component of the conventional cooling agent is a high molecular polymer emulsion such as a benzoprum emulsion, or the like, which is sprayed in the surface of the greenhouse film. After drying, a colored adheror is formed, and the shadow and reflection of the s...
