Abstract
The invention discloses a foam heat insulation brick made from domestic waste burning desulfurized lime, and relates to the technical field of energy-saving building material exploitation and building interior and exterior wall tile masonry. The formula of the foam heat insulation brick comprises 10-90% of domestic waste burning desulfurized lime powder, 1-40% of fine sands, 5-30% of cement, and 0.1-5% of an additive. The foam heat insulation brick is made through the following steps: mixing above raw materials in water, fully stirring the raw materials and water for 4-8min, pouring the obtained solution to a die, heating the solution to 80-100DEG C, foaming the heated solution for 50-70min, demolding the obtained product, and cutting the demolded product to form required specifications. The foam heat insulation brick has the advantages of low density, small heat conductivity, good stable performances, low engineering cost, excellent sound insulation effect and environment protection performance, and wall material use standard reaching.
Description
Technical field
The present invention relates to energy-saving building materials exploitation and building inside and outside wall brick setting technical field, be specifically related to a kind of foamed heat insulating brick utilizing consumer waste incineration desulfurization Calx to prepare.
Background technology
Climate warming and energy shortage oneself become the two big severe challenges that Global Sustainable Development faces.In coming few decades, building energy consumption will become main energy resource consumption growth point, the energy consumption (life energy consumption, heating air conditioning etc.) produced during using including the energy consumption (construction material, Architectural Equipment, construction etc.) produced during architecture construction and building.Numerical monitor according to statistics, nearly 40,000,000,000 square metres of the construction area that China is existing, 95% is above high energy consumption building.Therefore, building energy conservation is own through becoming one of China's important measures realizing sustainable development and the national energy-saving object of planning.
In building energy conservation, building structure external and internal wall is used the aerated bricks of lightweight intensity or foamed bricks is the important form realizing building energy conservation.
In China, building materials industry belongs to resource-hungry industry, and physical resources consumption accounts for more than the 90% of raw material proportion.In order to comply with the demand for development of China's recycling economy, it is necessary to improve the utilization of regenerated resources in building material product, digest and assimilate various consumer waste incineration desulfurization Calx in a large number, to realize the technological transformation of " minimizing, recycling, resource ".
There is more than 200 municipal solid waste incinerator in China, annual nearly 20,000,000 tons of the consumer waste incineration desulfurization Calx produced, but it produces and recycling does not cause the biggest attention, it is common that directly use the mode of air storage or landfill to process.Along with Urbanization in China strides forward the most in big strides, consumer waste incineration desulfurization Calx exacerbates the nervous situation of soil and environmental pollution, badly influences the coordinated development of social economy and ecological environment.Therefore, the comprehensive utilization strengthening consumer waste incineration desulfurization Calx is extremely urgent.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of foamed heat insulating brick utilizing consumer waste incineration desulfurization Calx to prepare.
In order to solve the problem existing for background technology, a kind of foamed heat insulating brick utilizing consumer waste incineration desulfurization Calx to prepare of the present invention, its formula is: consumer waste incineration desulfurization Calx powder body 10%-90%, fine sand material 1%-40%, cement 5%-30% and additive 0.1%-5%；Being mixed by above-mentioned raw materials use water, after being sufficiently stirred for 4-8 minute, pour mould into and be heated to 80-100 DEG C, after foaming 50-70 minute, de-system forms, and cuts into required specification after depanning.
As preferably, the fineness of described fine sand material is less than 2.36mm.
As preferably, the fineness of described consumer waste incineration desulfurization Calx powder body is less than 0.075mm.
As preferably, described additive is foaming agent.
Present invention have the beneficial effect that density is low, thermal conductivity is little, firm performance is good, construction costs is low, there is excellent soundproof effect and environmental-protecting performance, and reach materials for wall use standard.
Detailed description of the invention
This detailed description of the invention adopts the following technical scheme that its formula is: consumer waste incineration desulfurization Calx powder body 10%-90%, fine sand material 1%-40%, cement 5%-30% and additive 0.1%-5%；Being mixed by above-mentioned raw materials use water, after being sufficiently stirred for 4-8 minute, pour mould into and be heated to 80-100 DEG C, after foaming 50-70 minute, de-system forms, and cuts into required specification after depanning.
Further, the fineness of described fine sand material is less than 2.36mm.
Further, the fineness of described consumer waste incineration desulfurization Calx powder body is less than 0.075mm.
Further, described additive is foaming agent.
This detailed description of the invention has the advantage that
(1), light weight: its density is at 500-900kg/m3Between, can effectively alleviate the load of building；
(2), thermal conductivity is little: its heat conductivity, between 0.05-0.01, can effectively reduce the capacity of heat transmission of building masonry wall, have good heat preservation property；
(3), intensity is good: keeping good firm performance and ageing resistace by adding of special preparation, comprcssive strength is 3.5-10Mpa, frost resistance is mass loss 2.0, loss of strength 18.0.It is all inorganic material, the life-span same with building；
(4), construction costs is low: with consumer waste incineration desulfurization Calx powder body as primary raw material, by adding cement, foamed molding is prepared from, and technique is simple, and construction costs is low；
(5), soundproof effect is good: keeping each self-enclosed by the hole of the foamed heat insulating brick of foaming, the sound insulation of its 30mm can reach more than 52 decibels, fully solves the privacy of space；
(6), A level fire protecting performance: the composition of foamed heat insulating brick 97% is inorganic matter, and other is foaming agent and stabilizer, and for incombustible material, foamed heat insulating brick hole guarantees good fire resistance when being each enclosed in certain thickness.
Embodiment:
According to the mass fraction, consumer waste incineration desulfurization Calx powder body 10%-90%, fine sand material 1%-40%, cement 5%-30%, foaming agent 0.1-5% are weighed；Being mixed by above-mentioned raw materials use water, pour mould into and heat 90 degree, foam 1 hour after being sufficiently stirred for 5-6 minute, de-system forms, and cuts into required specification after depanning.
After preparation, the density of sample is 500-900kg/m3, heat conductivity be 0.03-0.01, comprcssive strength be 3.5-10Mpa, frost resistance be mass loss 2.0, loss of strength 18.0, fire rating reaches A1 level, and product specification is 100-600mm × 100-900mm × 25-1000mm.
