preparation example Construction

[0019] A preparation method of a concrete curing agent. The preparation method includes the following steps:

[0020] (1) According to the mass ratio of 6:1:12~16, take tetrabutyl titanate, aminophenyltrialkoxysilane and anhydrous ethanol for 15min ultrasonic vibration, and then add 3~5 times the mass of anhydrous ethanol 0.01 mol / L citric acid solution, mix evenly, put it into the reaction kettle, add 5-10% of the weight of tetrabutyl titanate additives, stir at 60-80℃ for 2h;

[0021] (2) After the stirring, cool to room temperature and discharge, collect the discharged material, sonicate and centrifuge the discharged material, collect the precipitate, dry the precipitate at 90°C, crush, pass through a 500 mesh sieve, and collect Sieving the particles, ball milling the sieved particles and nano-silica at a mass ratio of 3-6:5 at 800r / min for 40 minutes, and collect the ball-milled material;

[0022] (3) In parts by weight, take 50-60 parts of acetone, 30-35 parts of toluene, 20-25...

Abstract

The invention discloses a method for preparing a concrete curing agent, and belongs to the field of curing agents. The method includes taking tetrabutyl titanate, aminophenyl trialkoxyl silane, anhydrous ethanol and citric acid solution, mixing uniformly, adding additive, stirring, cooling and collecting a product at 60-80 DEG C, performing ultrasonic processing and centrifugation on the product,collecting precipitate, drying the precipitate, smashing and sieving the precipitate, collecting sieved particles for ball milling, and collecting a ball milling product; and taking acetone, toluene,the ball milling product, hydroxyl terminated polymethyl silicone oil, acrylic acid, phenol, ammonium persulfate and catalyst for mixing, discharging, filtration and drying and the like to obtain theconcrete curing agent.

Description

Technical field [0001] The invention belongs to the field of curing agents, and specifically relates to a preparation method of a concrete curing agent. Background technique [0002] Concrete curing agent, also known as liquid curing agent or concrete sealant, is a water-based transparent and environmentally friendly solution, colorless, odorless and non-toxic. Concrete is composed of coarse granular aggregates and cement hydrates. In the process of concrete construction, the cement components undergo a very complex chemical reaction with water to form hard hydrates, which cement the aggregates filled in to form A structure with high compressive strength, and has the advantages of economy, durability, fire resistance, and high compressive performance. However, due to the inherent process of cement hardening, concrete has the inevitable shortcomings, that is, the microstructure contains a large number of intersecting capillary pores, resulting in concrete structures that are ofte...
