Embodiment 1

[0035] An environmentally-friendly thermal insulation material for exterior walls, calculated in parts by weight, with raw material components as shown in Table 1.

[0036] Among them, the foaming agent is a protein foaming agent (refer to "Fine Chemicals" Volume 28, Issue 1, January 2011 "Preparation and Performance of Rapeseed Meal Protein Concrete Foaming Agent" homemade).

[0037] The preparation method of the external wall environmentally friendly thermal insulation material includes the following steps:

[0038] Step 1. Preparation of foaming liquid: mix protein foaming agent, tea saponin and sucrose, and stir evenly;

[0039] Step 2. Preparation of the main body of the thermal insulation material: Mix Portland cement, fly ash, glass fiber (length 6-8mm) and grapefruit peel fiber (4-6mm) uniformly and fully, add appropriate amount of water and stir to obtain cement slurry , While stirring, add the mixture of water-based epoxy resin (Dow Chemical DER916), water-based epoxy curing...

Embodiment 2

[0043] The difference from Example 1 is that the raw material components are as shown in Table 1 in parts by weight.

Abstract

The invention discloses an exterior wall environmental-friendly thermal insulation material. The exterior wall environmental-friendly thermal insulation material comprises, by weight, 70 to 75 parts of Portland cement, 17 to 20 parts of fly ash, 4 to 6 parts of a foaming agent, 1 to 2 parts of an aqueous epoxy resin, and 1 to 2 parts of an aqueous epoxy hardener. The advantages are that: the aqueous epoxy resin is high in bonding force, is capable of increasing bonding force of concrete among bubbles in foamed concrete layers so as to form a whole body, realize co-force loading, increase foamed concrete layer strength, and the binding firmness of foamed concrete layers with compact concrete layers; and in addition, after adding of the aqueous epoxy resin, thermal insulation layer surface is more smooth, after moulding, the morphology is more complete. The aqueous epoxy resin is also capable of achieving fixing and anti-cracking effects, and increasing structure strength and prolongingservice life obviously.

Description

Technical field [0001] The present invention relates to building materials, and more specifically, it relates to an environmentally friendly thermal insulation material for external walls. Background technique [0002] Building thermal insulation is a measure to reduce the indoor heat emission of a building. Measures are mainly taken from the building envelope structure, which plays an important role in creating a suitable indoor thermal environment and saving energy. [0003] The patent with the announcement number CN104761283B discloses an external wall thermal insulation material, which includes the following raw materials in parts by weight: 25-45 parts of slag Portland cement, 5-10 parts of fly ash, and 1-3 parts of foaming agent Parts, 0.1-0.7 parts of sodium silicate, 20-40 parts of water; among them, the blowing agent is 30-70wt% dodecyl dimethyl amine oxide and 30-70wt% N-dodecyl glycol amine mixture. [0004] This kind of external wall insulation material is formed only b...
