Embodiment 1

[0035] An environmentally friendly thermal insulation material for external walls, the raw material components are shown in Table 1 by weight parts.

[0036] Among them, the foaming agent is a protein foaming agent (refer to "Fine Chemical Industry" Volume 28, No. 1, January 2011 "Preparation and Performance of Rapeseed Meal Protein Concrete Foaming Agent" self-made).

[0037] The preparation method of the external wall environmental protection thermal insulation material comprises the following steps:

[0038] Step 1, preparation of foaming liquid: mixing protein foaming agent, tea saponin and sucrose, stirring evenly;

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

Embodiment 2

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

Abstract

The invention discloses an external wall environmental protection thermal insulation material. The raw materials include the following components in parts by weight, 70-75 parts of Portland cement; 17-20 parts of fly ash; 4-6 parts of foaming agent; water-based 1-2 parts of epoxy resin; 1-2 parts of water-based epoxy curing agent. The invention has the following advantages: the water-based epoxy resin has strong cohesive force, and the cohesive force of the concrete between air bubbles is improved in the foamed concrete layer, so that it forms a whole and is jointly stressed, and the strength of the foamed concrete layer is improved. The significance of strength and the firmness of the bond between the foam concrete layer and the dense concrete layer; in addition, after adding water-based epoxy resin, the surface of the insulation layer will be smoother and the shape will be more complete after molding. Therefore, the water-based epoxy resin also plays a role in shaping and preventing cracking, which significantly improves the structural strength and service life.

Description

technical field [0001] The present invention relates to building materials, more specifically, it relates to an external wall environmental protection thermal insulation material. Background technique [0002] Building thermal insulation is a measure to reduce the indoor heat of a building to be emitted to the outside. Measures are mainly taken from the building's external enclosure structure, which plays an important role in creating a suitable indoor thermal environment and saving energy. [0003] The patent with the notification number CN104761283B discloses a thermal insulation material for external walls. The thermal insulation material 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; wherein, the blowing agent is 30-70wt% dodecyl dimethyl amine oxide and 30-70wt% N-dodecyl glycol amine mixture. [0004] Thi...
