Problems solved by technology

[0004] Now transparent heat-insulating coatings use nano-rare earth materials as shielding heat-insulating materials, and almost all water-based resins can be used as film-forming resins, but the water resistance, aging resistance, self-cleaning property, corrosion resistance and other properties of the coating are not very good. Ideal, due to the short life of the coating and poor adhesion to dirt, it is very necessary to improve the atmospheric corrosion resistance, stain resistance, heat and humidity resistance, and self-cleaning properties of the coating film

Abstract

The invention relates to a PEEK-modified polyurethane infrared and ultraviolet fully shielding waterborne transparent thermal insulating paint. The PEEK-modified polyurethane infrared and ultravioletfully shielding waterborne transparent thermal insulating paint is composed of PEEK-modified waterborne polyurethane resin, solubilizer, substrate accelerator, nanometer transparent thermal insulatingagent, nanometer photocatalysts, transparent nanometer pigments, auxiliaries and water, wherein the PEEK-modified waterborne polyurethane resin is prepared by synthesizing amine-modified PEEK, low-polymer polyols, diisocyanate and hydrophilic modifier into a prepolymer under the action of catalysts and then performing alcohol and amine chain extension. The prepared PEEK-modified polyurethane infrared and ultraviolet fully shielding waterborne transparent thermal insulating paint is excellent in adhesion force, corrosion resistance, ageing resistance, humidity and heat resistance, wearing resistance, self-cleaning properties, radiation resistance, static resistance, fire resistance and mechanical performance, reaches a visual light transmittance near to 70%, capable of fully shielding ultraviolet and infrared rays and significant in thermal insulating performance. Therefore, the PEEK-modified polyurethane infrared and ultraviolet fully shielding waterborne transparent thermal insulating paint can be widely applied to surface thermal insulation and protection of building glass, vehicle glass, engineering plastics, steel structures and cement.

Description

technical field [0001] The invention relates to a water-based heat-insulating coating, in particular to a water-based transparent heat-insulating coating of PEEK modified polyurethane fully shielding infrared rays and ultraviolet rays, and belongs to the technical field of water-based functional coatings. Background technique [0002] China has nearly 40 billion square meters of buildings, 95% of which are non-energy-efficient buildings. Compared with developed countries with similar climate conditions, my country's energy consumption per square meter for heating and cooling is about three times that of developed countries, but the comfort level is far inferior to that of people. Therefore, the new national building energy-saving standard stipulates that the energy-saving of new buildings must reach 50%, and by 2020, the total energy consumption of buildings in the whole society should reach the total target of 65%. According to data, China's total energy consumption is incre...
