Embodiment Construction
[0020] Below in conjunction with embodiment, the present invention will be further described:
[0021] 1. The ingredients of the attapulgite thermal insulation and waterproof coating are composed of the following components by weight percentage: Paste attapulgite clay 55%, plant fiber 15%, rock wool 8%, modified emulsified asphalt 18%, polyvinyl alcohol 2.5% and sodium carboxymethylcellulose 1.5%.
[0022] 2. The preparation method of attapulgite thermal insulation and waterproof coating: first add plant fiber, rock wool, polyvinyl alcohol and sodium carboxymethyl cellulose to the paste-like attapulgite clay for mixing and stirring, and then heat slowly. The heating temperature is controlled at 80- At 95°C, finally add the modified emulsified asphalt to the mixture of paste-like attapulgite clay, plant fiber, rock wool, polyvinyl alcohol and sodium carboxymethyl cellulose and continue to heat slowly. The heating temperature is controlled at 85-100°C. The finished product is a...

Abstract
The invention discloses a thermal insulation and waterproof attapulgite coating. The technical scheme is characterized in that the thermal insulation and waterproof attapulgite greenhouse coating is prepared from paste attapulgite clay, plant fiber, rock wool, modified emulsified asphalt, polyvinyl alcohol and sodium carboxymethylcellulose. a finished product of the thermal insulation and waterproof attapulgite coating for a solar greenhouse is obtained with production processes of batching, stirring, heating and emulsification. The coating has the functions of being light, waterproof, anti-aging, thermal-insulating and the like. The thermal insulation and waterproof attapulgite coating is suitable for being applied to the outer surface layer of greenhouse thermal insulation coverage materials such as straw curtains, straw mats, cattail mats, paper quilts or cotton quilts, can prolong the service life of the thermal insulation coverage material by 4-5 years or longer, has good waterproof and heat preservation effects, can increase the temperature by 8-10 DEG C as compared with straw curtains under the same condition, can prevent the fungus infection in a greenhouse, and the thermalinsulation coverage material coated with the coating provided by the invention is light and convenient to coil and easy to store and collect.
Description
technical field [0001] The invention relates to a waterproof coating, in particular to an attapulgite thermal insulation waterproof coating. Background technique [0002] At present, the traditional thermal insulation covering materials used in greenhouses include straw curtains, grass thatch, cattail mats, paper quilts, cotton quilts, etc. These thermal insulation covering materials are easy to obtain, simple to manufacture, and low in cost. , The disadvantage is that the waterproof performance is poor, the service life is short, it is easy to be soaked by rain and snow, and it is easy to rot after being damp, which reduces the thermal insulation performance. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art and provide a porous, light, heat-preserving and waterproof attapulgite heat-preservation and waterproof coating. [0004] The attapulgite thermal insulation and waterproof coating is composed of paste at...
