Problems solved by technology

[0009] In view of the deficiencies in the prior art, the inventor thought of coating the reflective heat-insulating paint on the surface of the reflective concrete tank car to control the temperature rise. However, many types of heat-insulating paints in the prior art cannot meet the requirements. Some When this type of paint is coated on the tank body, the adhesion to the steel is insufficient, and there is not enough reflective heat insulation effect, and some paints will peel off after a long time in the sun

Abstract

The invention relates to the field of heat insulation of concrete, in particular to a light-reflecting heat-insulating coating for a concrete tank truck, and a preparation method and a use method thereof. The light-reflecting heat-insulating coating for the concrete tank truck is prepared from the following components in parts by mass: a space polymer emulsion, boron nitride, titanium dioxide, superfine aluminum foil, hollow nanometer glass microspheres, a curing agent, a mildew-proof and alga-proof agent and water. The preparation method of the light-reflecting heat-insulating coating for theconcrete tank truck comprises the following steps: mixing resin, adding light-reflecting and heat-insulating substances, and adding auxiliaries and water. The use method of the light-reflecting heat-insulating coating for the concrete tank truck comprises the following three steps: pretreatment of an object to be brushed; coating of the surface of a tank body; and curing. The light-reflecting heat-insulating coating for the concrete tank truck has relatively high heat reflection on light, and infrared heat reflectivity can reach 90% or above.

Description

technical field [0001] The invention relates to the field of concrete heat insulation, and more particularly, to a reflective heat insulation paint for a concrete tanker, a preparation method and a use method thereof. Background technique [0002] After the ready-mixed concrete is out of the trough, it generally needs to be transported by a concrete tanker. The transportation and waiting time for unloading usually take half an hour to an hour, and it takes longer to encounter traffic jams. Under the condition of sunshine, the temperature of ready-mixed concrete in the irrigation increases greatly, especially in summer, the temperature rise of sunshine can reach 5-10℃. The temperature rise has a great negative impact on the formation of waterproof concrete, and it is especially easy to cause cracking and leakage of large-scale concrete. [0003] In the prior art, there are mainly the following technologies to avoid the influence of the concrete temperature rise in the concre...
