Embodiment 1

[0030] 1. Ingredients

[0031] Weigh by parts by weight:

[0032] Component A: 16 parts by weight of biomass-loaded nano-ions; 6 parts by weight of acid-modified aluminum stearate; 11 parts by weight of γ-glycidyl etheroxypropyl trimethoxysilane; isopropyl 3-aminocrotonate 3 parts by weight; 22 parts by weight of compatibilizer tetrahydrofuran;

[0033] Component B: 22 parts by weight of DLP type photosensitive resin; 0.3 parts by weight of 5-aminolevulinic acid; 46 parts by weight of styrene; 3 parts by weight of pigment; 5 parts by weight of acrylic resin;

[0034] 2. How to use

[0035] 1) Mix the paint of component A, shear and mix evenly in a high-speed shearing machine, dilute component A with isopropyl acetate after mixing, and then spray it on the concrete surface with a spray gun to obtain the first coating. The thickness of the first coating is 50-60 microns; the amount of isopropyl acetate is one-eighth to one-tenth of the weight of component A;

[0036] 2) Stir...

Abstract

The invention belongs to the technical field of paint and particularly relates to paint for preventing concrete neutralization and an application method thereof. The paint for preventing the concrete neutralization is prepared from a component A and a component B, wherein the weight ratio of the component A to the component B is 1 to 3; the component A is prepared from biomass-loaded nano ions, acid modified aluminum stearate, gamma-glycidyloxypropyltriethoxysilane, isopropyl 3-aminocrotonate and tetrahydrofuran; and the component B is prepared from DLP type photosensitive resin, 5-aminolevulinic acid, styrene, pigment and acrylic resin. The paint provided by the invention has good waterproof and one-directional breathable properties; biomass-loaded nano ions on the DLP type photosensitive resin and a pore structure of a fiber framework can prevent external rainwater and harmful gas from permeating into the structure, and moisture in the structure can also be diffused, so that the cohesive force between a coating and the structure is not influenced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-concrete neutralization coating and an application method thereof. Background technique [0002] The cement hydration product Ca(OH) exists in concrete 2 etc., which are strong alkali substances and are easily soluble in water. When concrete contacts with water, Ca(OH) 2 will be dissolved. When concrete is placed in air or water with high carbon dioxide content, its surface absorbs carbon dioxide in the air or water and calcium hydroxide to form calcium carbonate, the alkaline substances gradually disappear, and the pH value in the concrete drops. This phenomenon of losing alkalinity It is called concrete neutralization. [0003] The neutralization of concrete not only causes volume shrinkage of the concrete itself, but also produces tiny gaps, which will have adverse effects on the concrete strength, frost resistance, permeability and other indicators, es...
