Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention, and should not be considered as limiting the scope of the present invention.

[0026] The dyed seal hardener for concrete described in the present invention is formed by mixing the following raw material components in mass percentage: 25%-65% of pseudo-boehmite sol, 4%-10% of acrylic resin emulsion, surface 0.1% to 1% of active agent, 3% to 8% of silane coupling agent, 1% to 5% of rigid nano particles, 1% to 6% of inorganic toner, 6% to 11% of ethanol, and the balance is distilled water; Nano rigid particles are SiC, BC 4 、C 3 N 4 , Fe 3 o 4 or TiO 2 one or a combination of several.

[0027] The preparation method of the dyed sealing hardener for concrete comprises the following steps:

[0028] (1) Weigh each component according to the following...

Abstract

The invention relates to the technical field of building materials and aims to provide a preparation method of a dyed sealing hardener for concrete. Including: first take half of the mass of ethanol and distilled water, stir well, then add pseudo-boehmite sol and acrylic resin emulsion; heat, stir and cool to room temperature; take the remaining ethanol and distilled water, stir well in another container, and then sequentially Add inorganic toner and surfactant, stir at room temperature; mix and stir the mixture obtained twice, add silane coupling agent, add nano rigid particles after stirring, ultrasonic treatment after thorough stirring, and stir under water bath conditions; Cool down to room temperature after completion to obtain the product. The invention can change the apparent color of concrete; the product is a water-based material, and the construction is simple, and the treated concrete floor has the characteristics of high hardness, high wear resistance, high gloss, etc.; the preparation process is simple, the reaction process is easy to control, and the reaction conditions are mild. Especially suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a preparation method of a dyed seal hardener for concrete. Background technique [0002] Concrete is the most widely used man-made building material, and is widely used in various structural projects; however, due to the limitations of the concrete material itself and the construction level, many infrastructures, industrial plant floors, etc. have long been damaged, and the surface has potholes, weathering, Dust, sand, and peeling phenomena lead to poor wear resistance and short service life. They can no longer adapt to the needs of modern production environments and are in urgent need of renovation; Cover a layer of epoxy floor paint, etc.; but the above-mentioned solutions are too cost-effective, and the places of use are limited. For example, laying ceramic tiles or floor tiles, in addition to high labor and material costs, more importantly, the place of use is limited. Gene...
