Embodiment 3

[0053] The third group (embodiment 3.1-3.3)

[0054] In component A Hardener Epoxy resin (trade name 637E-35); Thinner to ethyl acetate.

[0055] Put the curing agent into the reaction kettle with agitator, raise the temperature of the material to 120°C under stirring, and vacuumize to reduce the pressure in the reaction kettle to -0.09MPa, so that the moisture content brought by the raw materials is reduced to Below 0.05% of the total amount of materials added, after cooling down to 45°C, add 10 parts of diluent, mix under normal pressure for 30 minutes, cool down to below 35°C, and obtain A component.

[0056] In component B waterproof film former It is a two-terminal amino polyether (trade name PEA), and its molecular weight is 2000±200; UV blocker It is yellow or red or green transparent nanometer ferric oxide; the nanometer ferric oxide is also thermochromic agent , due to the certain complexation of yellow or red or green transparent nanometer ferric oxide an...

Abstract

The invention relates to the field of manufacturing of exterior wall waterproof and protective paints for buildings and specifically discloses a cured type waterproof protective and thermochromic paint and a preparation method thereof. The cured type waterproof protective and thermochromic paint is prepared from a component A and a component B; the component A is prepared from 50-90 parts of curing agent and 0-100 parts of diluent in parts by weight; the component B is prepared from 100 parts of waterproof film forming agent, 0.5-40 parts of ultraviolet separant, 0-25 parts of thermochromic color-changing agent and 0-5 parts of dispersant in parts by weight. The cured type waterproof protective and thermochromic paint has the capabilities of effectively isolating moisture from seeping into a protected inkjet decoration coating and effectively isolating the corrosion of acid rain to the inkjet decoration coating, is remarkable and adjustable in thermochromic effect and has the isolation rate to ultraviolet up to 83%. The preparation method disclosed by the invention is simple and feasible and can be applied to industrial production.

Description

【Technical field】 [0001] The invention relates to the technical field of waterproof and protective coatings for exterior walls of buildings, in particular to a curing type waterproof protective and thermochromic coating and a preparation method thereof. 【Background technique】 [0002] With the acceleration of urbanization, the increasing scale of cities and the increasing density of buildings not only bring convenience to life, but also make people's living environment and visual space oppressive, and have a negative impact on people's mental health. . [0003] For this reason, architects strive to improve the engineering aesthetics structure. However, these current methods have insurmountable defects, such as: glass curtain wall, although beautiful, is prone to sunlight reflection and focus pollution; covered tiles, although the beautification effect is good But it is easy to weather and fall off, causing safety hazards. [0004] Color coatings have attracted much attenti...
