Embodiment 1

[0024] Embodiment 1, the method for preparing vitrified microspheres and polystyrene particle composite thermal insulation mortar by foaming agent modification, operates according to the following steps: pour cement, fly ash, redispersible latex powder, polypropylene fiber, foaming agent Put it into a high-speed mixer and mix evenly, then add vitrified microspheres and polystyrene particles to mix into a uniform material to obtain a composite thermal insulation mortar.

Embodiment 2

[0025] Embodiment 2, the preparation method of animal protein whipping agent are as follows:

[0026] (1) Liquefaction: mix powdered animal bones or skin and hair as the source of animal protein with calcium hydroxide and sodium hydroxide in a weight ratio of 1:1:0.2, and then add the weight of powdered animal bones or skin and hair 3 times of water as a solvent, stirred to form a thick paste, set aside;

[0027] (2) Hydrolysis: Add the paste into a container with a stirring rod, stir, install a condenser to condense, and heat up to 100°C; stop the reaction for 10 hours, cool and filter, collect the filtrate, and neutralize the filtrate with hydrochloric acid to The pH value is 7.0, heated and distilled to concentrate to a density of 1.1 g / ml, and sodium benzoate preservative is added according to the weight percentage of the concentrated solution (Example 2%) and spray-dried to obtain an animal protein foaming agent.

Embodiment 3

[0028] Embodiment 3, the preparation method of animal protein foaming agent are as follows:

[0029] (1) Liquefaction: mix powdered animal bones or skin and hair as the source of animal protein with calcium hydroxide and sodium hydroxide in a weight ratio of 1:1.5:0.4, and then add the weight of powdered animal bones or skin and hair 6 times of water as a solvent, stirring to form a thick paste, set aside;

[0030] (2) Hydrolysis: Add the paste into a container with a stirring rod, stir, install a condenser to condense, and heat up to 100°C; stop the reaction for 10 hours, cool and filter, collect the filtrate, and neutralize the filtrate with hydrochloric acid to The pH value is 7.0, heated and distilled to concentrate to a density of 1.25 g / ml, and sodium benzoate preservative is added according to the weight percentage of the concentrated solution (Example 2%) and spray-dried to obtain an animal protein foaming agent.

Abstract

The invention relates to a preparation method for composite thermal insulation mortar. The method comprises the following steps: cement, fly ash, redispersible latex powder, polypropylene fiber, animal protein foaming agent and lauryl sodium sulfate foaming agent are poured into a high speed mixer to be evenly mixed, and then the mixture is added with vitrified micro bubbles and polystyrene particles to be evenly mixed to obtain the composite thermal insulation mortar. The invention has the advantages that the lauryl sodium sulfate foaming agent modified by using the animal protein foaming agent is rapidly dry-mixed and stirred to obtain the composite thermal insulation solid mortar, and the rapid production is favorable for saving energy and reducing consumption; the composite thermal insulation mortar during the construction is easy to uniformly stir, is not easy to layer, is long in opening time and also has the advantages of easy sale by bulk, easy coating and easy scraping, heat preservation, energy saving, simple operation and convenient construction; and the coefficient of heat conductivity is 0.055-0.067 W / m.k..

Description

technical field [0001] The invention relates to a preparation method of composite thermal insulation mortar, which mainly relates to a method for preparing composite thermal insulation mortar of vitrified microbeads and polystyrene particles by modifying a foaming agent. Background technique [0002] The amount of composite thermal insulation mortar is increasing. The composite thermal insulation mortar using foaming agent has the characteristics of low cost, good thermal insulation performance, good construction performance, high compressive strength and high compressive shear bond strength. Although the amount of foaming agent used is small, the choice of foaming agent has a great influence on the preparation or performance of composite thermal insulation mortar. Contents of the invention [0003] The object of the present invention is to provide a method for preparing vitrified microspheres and polystyrene particles composite thermal insulation mortar by modifying foami...
