Abstract

A kind of New Building Materials that can be used for construction industry, can replace common brick, watt and concrete.

Its principle is according to structure and the mineral composition and the physicochemical property of soil, to mix the polymer chain hydrocarbon that some have polar group (as: hydroxyl, carboxyl, aldehyde radical, itrile group etc.) in soil.Physics-Chemical bond takes place by polar functional group and soil particle surface in these macromolecular materials, is bound up firmly thereby make between the soil particle.

The New Building Materials of making in this way, cost is low, invests for a short time, and save energy, and can reduce traffic capacity is particularly useful for general covil construction.

Description

The at present domestic brickmaking of generally adopting, a watt method is, fetching earth is starting material, Jia Shui with become mud, through the brick making machine moulding, airing, the loading of kiln sintering forms.Therefore, general Bricks and Tiles Plant all will build in and have a good transport service, the competent place of the energy, and must build the sintering kiln.This just makes some have inconvenient traffic, and the place of energy scarcity and mountain area are difficult to make brick and tile.

At above problem, the invention provides a kind of New Building Materials and preparation method thereof, be used for replacing the vitrified brick of covil construction, watt and a part of concrete preform.

This invention utilizes soil to have this characteristic of surface charge, according to native mineral composition, structure, the difference of physicochemical property, mix the high chain hydrocarbon that some have polar group (as hydroxyl, aldehyde radical, carboxyl, itrile group etc.) targetedly, physical bond can take place with the soil particle surface in the polar functional group of these macromolecular materials.With kaolin is example, when the hydroxyl in its surface and the polymer chain hydrocarbon meets, can produce hydrogen bonded:

In the formula: M represents silicon or the metal ions such as aluminium, magnesium in the soil.

: represent hydrogen bond.

By this combination, polymerization between the chain hydrocarbon molecule or friendship are mixed up with soil particle is bonded together firmly, formation has the type material of certain intensity, in order to replace concrete or burned brick, watt and the concrete of some special purpose.For example, with this type material as precast members such as pipelines, and the lining layer material of roofing layer, tunnel or channel.

Because soil is inexhaustible material, therefore can gather materials on the spot at the construction field (site), make on the spot, do not need sintering, technology is simple.Not only easy to use, and invest for a short time, cost is low, remarkable benefit.

The macromolecular material that mixes in the soil, is refined in the waste liquid and gets from waste vapour by chemical plant or refinery, can be used as co-production.The incorporation of macromolecular material generally is lower than 2% of soil, therefore make in this way no vitrified brick, watt, cost a little less than ordinary fired brick, watt.

A kind of embodiment provided by the invention is: with the loess or the clay of northwest loess plateau, mix 2% high-molecular polythene class chain hydrocarbon, method extrusion molding with common brickmaking base, (about 20 ℃) dried in the shade 20 days at normal temperatures, or under higher temperature (60-80 ℃) air-dry 6 hours, promptly can be made into no vitrified brick.By adjusting the material composition and the incorporation of polymer chain hydrocarbon, the intensity of made brick can be at 50-100kg/cm ²Between select arbitrarily.Equally, utilize aforesaid method, also can utilize this novel material to make various precast members with reference to the technological process of giving system concrete pipe or other precast member.In a word, satisfying under the prerequisite of requirement of strength, utilizing this New Building Materials, can replace concrete or various conventional building materials.In the normal domestic building, this is the cheap material of construction of a kind of comparatively ideal.

Claims

1, a kind of novel material of construction, it is characterized in that in soil, mixing high chain hydrocarbon with polar group, the solubilizing agent person of outstanding talent makes between soil and these macromolecular materials, and physics-chemical reaction takes place, be bound up thereby make between the soil particle, and then the structure material of making.

2, as the said New Building Materials of claim 1, it is characterized in that mixing in the high chain hydrocarbon material in the soil, have any one in hydroxyl, carboxyl, aldehyde radical, the itrile group isopolarity group or several.
