Problems solved by technology

[0011] 1. XPS extruded board and EPS expanded polystyrene board, as the main body of the external wall insulation system, although they have good thermal insulation function, but because they are all organic materials, they will cause adverse effects on the environment
[0012] 2. The external wall insulation systems of the two types of building walls adopt a multi-level structure, and some components need to be assisted by certain riveting fasteners. Therefore, not only the material cost and construction cost are high, but also the construction difficulty is relatively large, and it is easy to produce Hollowing and cracking with fatal consequences for the insulation system

Embodiment 1

[0031] A new type of inorganic thermal insulation mortar, which is composed of cement, natural lightweight aggregate and high molecular polymer, according to the percentage by weight:

[0032] Cement 50%;

[0033] Natural lightweight aggregate 47%

[0034] High molecular polymer 3%.

[0035] The natural lightweight aggregate is pumice pretreated by high temperature and negative high pressure, and the pretreated natural lightweight aggregate increases the volume of the product and strengthens the heat preservation effect. The high molecular polymer includes the SEAL80 waterproof material of American National Starch Company and the product produced by Wacker Company of Germany to increase the bonding performance of the product.

Embodiment 2

[0037] A new type of inorganic thermal insulation mortar, which is composed of cement, natural lightweight aggregate and high molecular polymer, according to the percentage by weight:

[0038] Cement 27%;

[0039] Natural lightweight aggregate 70%;

[0040] High molecular polymer 3%.

[0041] The natural lightweight aggregate is pretreated with high temperature and negative high pressure vermiculite, and the pretreated natural lightweight aggregate increases the volume of the product and strengthens the heat preservation effect. The high molecular polymer includes the SEAL80 waterproof material of American National Starch Company and the product produced by Wacker Company of Germany to increase the bonding performance of the product.

Embodiment 3

[0043] A new type of inorganic thermal insulation mortar, which is composed of cement, natural lightweight aggregate and high molecular polymer, according to the percentage by weight:

[0044] Cement 45%;

[0045] Natural lightweight aggregate 54.9%;

[0046] Polymer 0.1%.

[0047] The natural lightweight aggregate is expanded perlite pretreated by high temperature and negative high pressure, and the pretreated natural lightweight aggregate increases the volume of the product and strengthens the thermal insulation effect. The high molecular polymer includes the SEAL80 waterproof material of American National Starch Company and the product produced by Wacker Company of Germany to increase the bonding performance of the product.

Abstract

The present invention belongs to the field of building material and chemical technology, and is especially one kind of environment friendly heat insulating inorganic mortar for outer wall of building. The mortar consists of cement 27-50 wt%, natural light aggregate 47-70 wt% and polymer 0.1-3 wt%. The present invention is environment friendly, low in cost and high in strength, and may be used to adhere tile.

Description

Technical field: [0001] The invention belongs to the technical field of building materials and chemistry, and relates to a novel environmentally friendly building waterproof and thermal insulation mortar for construction engineering, in particular to a novel inorganic thermal insulation mortar for exterior walls. Background technique: [0002] At present, the external wall insulation system of building walls mainly adopts the following two structures and insulation methods: [0003] Method 1. Stick the XPS extruded board (insulation board) to the base wall with a special adhesive for benzene board, and then use rivets (such as: plastic expansion nails) to strengthen the fixation; coat the outer surface of the XPS extruded board After the first layer of anti-seepage and anti-crack polymer modified plaster mortar, the alkali-resistant glass fiber mesh cloth is embedded in the plaster mortar; the outer surface of the alkali-resistant glass fiber mesh cloth is coated with the se...
