Concrete foaming agent preparation method

Abstract

The invention discloses a concrete foaming agent preparation method. A foaming agent, laurinol, rosin soap solution, gelatin, acrylic acid emulsion, cement sealant and water are utilized as raw materials, the raw materials are evenly mixed and stirred in a reaction kettle, and the raw materials are matched according to the following matching that the proportion of the foaming agent is 12%, the proportion of the laurinol is 1%, the proportion of rosin soap solution is 13%, the proportion of the gelatin is 2%, the proportion of the acrylic acid emulsion is 5%, the proportion of the cement sealant is 2%, and the proportion of water is 65%. The preparation method comprises the steps of firstly adding water into the reaction kettle to be heated to be not lower than 95 DEG C; then adding the gelatin and the rosin soap solution and evenly stirring after dissolving; adding the foaming agent, the laurinol, the acrylic acid emulsion and the cement sealant to be fully stirred for 3 hours after temperature of solution in the reaction kettle in the last step is cooled to 45 to 50 DEG C, wherein stirring speed is controlled as 180 turns / minute. The foaming agent is an AES foaming agent or an AOS foaming agent. The foaming agent prepared through the preparation method has good stability, is suitable for varieties of cement, has small foam diameter, improves concrete strength and is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a concrete foaming agent. Background technique [0002] At present, the existing concrete foaming agents on the market produce foams with a diameter of 1-2 mm, poor stability, and easy foaming and foaming; when making block products, they are easy to crack, have poor waterproof ability, and poor heat preservation and heat insulation effects. Used for specific projects; harmful substances exist, which is not conducive to environmental protection; poor antifreeze solubility; small adhesive adhesion; high cost, large cement consumption and not conducive to storage; unreliable foam volume, unstable foaming, toughness Difference. Contents of the invention [0003] The purpose of the present invention is to improve the stability of the foaming agent, which can make foamed products more than three meters in one time without collapsing, improve its...
