Embodiment Construction

[0009] The invention provides a technical solution: a foamed concrete nano-reinforcing agent and its preparation method, the weight percentage of the raw materials used is: polyether 10-30%, acrylic acid 8-20%, initiator 8-20%, surface active Agent 1-10%, coagulation regulator 6-15%, catalyst 2-10%, deionized water 60-70%.

[0010] The steps of the preparation method are as follows: a. Weigh each raw material by weight percentage; b. Put deionized water in the reactor, then add polyether, when heated to 55°C-65°C, add acrylic acid and initiator dropwise to the reaction vessel In the container, reduce the temperature inside the reactor to 35°C-45°C, then stir the acrylic acid, initiator, polyether and deionized water for 10-20 minutes to make them evenly mixed; c. Add the coagulant to the remaining 25% to 30% deionized water, and fully stir at 35°C to 45°C for 0.2 to 1 hour; d. Maintain the temperature in the solution obtained in step c at 35°C to 45°C while Slowly pour the so...

Abstract

The invention discloses a nano-reinforcing agent for foamed concrete and a preparation method of the nano-reinforcing agent. The nano-reinforcing agent is prepared from raw materials in percentage byweight as follows: 10%-30% of polyether, 8%-20% of acrylic acid, 8%-20% of an initiator, 1%-10% of a surfactant, 6%-15% of a thickening time control agent, 2%-10% of a catalyst and 60%-70% of deionized water. The preparation method comprises steps as follows: a, the raw materials are weighed in percentage by weight; b, the deionized water is added to a reactor, polyether is added, acrylic acid andthe initiator are dropwise added to the reactor when the temperature is increased to 55-65 DEG C, the temperature in the reactor is reduced to 35-45 DEG C, and then acrylic acid, the initiator, polyether and the deionized water are stirred for 10-20 min to be uniformly mixed. The prepared nano-reinforcing agent is high in stability, has qualified performance and multiple functions of saving comprehensive cost of concrete, improving concrete workability and concrete strength and the like, meets the harmful substance standards, reduces cement consumption, and is simple to use and low in mixingamount and investment.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a nano-enhancer for foamed concrete and a preparation method thereof. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Lightweight concrete (foam concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it is formed to contain a large number of small closed pores, and Concrete products of considerable strength. The production of lightweight concrete (foamed concrete) is usually prepared by mechanical means to prepare foaming agent aqueous solution into foam. The specific operation is: mechanicall...
