Description
Technical Field
The invention relates to the technical field of C04B building materials, and particularly provides novel flame-retardant and moisture-proof mortar and a preparation method thereof.
Background
With the increasing awareness of environmental protection and safety of people, the requirements on the flame retardant property, durability and corrosion resistance of building materials are also higher and higher. The mortar is an important building material and has wide application in the field of buildings, and the comprehensive performance of the mortar also directly influences the service life and the processing result of the buildings. The mortar in the prior art can not meet the increasing development requirement of the building industry.
The invention discloses a high-efficiency corrosion-resistant mortar, which is disclosed in Chinese patent publication No. CN113105196A, wherein the corrosion resistance of the mortar is improved by researching the adding amount of raw materials such as high-alumina cement, quartz sand, sodium fluosilicate and the like in the mortar, but the flame retardant property and the waterproof property of the mortar are not reflected obviously, and the application range of the mortar in the field of building materials is limited.
The invention discloses a flame-retardant thermal insulation mortar for building construction and a preparation method thereof, wherein a Chinese patent with a patent publication number of CN112079601A discloses a flame-retardant thermal insulation mortar for building construction, a self-made flame-retardant additive is added into the disclosed patent, the problems of poor flame-retardant performance and mechanical performance of a thermal insulation material in the prior art are solved emphatically, but the corrosion resistance and waterproof performance of the mortar are not fully reflected, and meanwhile, the flame-retardant additive needs to be prepared in advance, so that the difficulty of a processing process is improved, and the large-scale use and popularization of industrial grade are not facilitated.
Therefore, the development of the mortar with excellent flame retardance, waterproofness and corrosion resistance has profound significance in the field of building materials.
Disclosure of Invention
In order to solve the technical problems, the invention provides a flame-retardant moisture-proof novel mortar in a first aspect, which comprises the following raw materials in parts by weight: 40-60 parts of Portland cement, 20-30 parts of first auxiliary material, 25-35 parts of second auxiliary material, 2-4 parts of air entraining agent, 2-3 parts of organic additive, 10-20 parts of pigment and filler, 1-3 parts of inorganic flame retardant, 2-5 parts of water reducing agent, 1-3 parts of first auxiliary agent and 0-4 parts of second auxiliary agent.
In some preferred embodiments, the first auxiliary material is at least one selected from the group consisting of ultrafine fly ash, calcium carbonate mineral powder, water granulated slag mineral powder and clay tailing powder.
In some preferred embodiments, the first auxiliary material is ultrafine fly ash, calcium carbonate mineral powder and water granulated slag mineral powder, and the mass ratio of the ultrafine fly ash, the calcium carbonate mineral powder and the water granulated slag mineral powder is (0.5-1): (0.7-1.9): (0.2-0.4).
In some preferred embodiments, the mass ratio of the ultrafine fly ash, the calcium carbonate mineral powder and the water granulated slag mineral powder is 0.7:1.3:0.3.
in some preferred embodiments, the second auxiliary material is selected from at least one of graphene oxide, quartz sand, blast furnace slag, fine sand, graphene and bentonite.
In some preferred embodiments, the second auxiliary material is graphene oxide, quartz sand, bentonite, and the mass ratio of graphene oxide, quartz sand, bentonite is (0.1-0.5): (2-3): (1.2-1.6).
In some preferred embodiments, the mass ratio of the graphene oxide to the quartz sand to the bentonite is 0.3:2.5:1.4.
in some preferred embodiments, the quartz sand has a particle size of 700-900 mesh.
In some preferred embodiments, the air entraining agent is selected from at least one of calcium lignosulfonate, sodium abietate, sodium tripolyphosphate, and rosin resin.
In some preferred embodiments, the air entraining agent is calcium lignosulfonate, sodium abietate, and the mass ratio of the calcium lignosulfonate to the sodium abietate is (0.8-1.4): (0.2-0.6).
