Description

Preparation method of a kind of gypsum brick and products thereof

The present invention relates to the preparation method of material of construction, particularly relate to preparation method of a kind of gypsum brick and products thereof.

Gypsum is the common used material of building trade, and consumption is very big, but because the restriction of state of the art, its performance can not satisfy people's requirement, shows that curing cycle is short, easily infiltration, intensity are low etc.

In addition, through secular observation, practice and research, we have found two special phenomena, one is to have more than 2000 year historical ancient Great Wall experiencing the how many times trials and hardships, after the earthshaking test, still can stand towering, hard as huge rock, though the brick that has weathering breakage, but the ditch between brick and the brick still closely connects together, find that by analysis the material of this ditch seam is a sticky rice syrup, lime and gypsum synthetic, exist a kind of having the qualities of plants glue, it has been penetrated in the material of connected brick, and molten with it be one, and hard inseparable; Another phenomenon is, we exist tartar by everyone tooth more or less, even all note brushing teeth after you, the each dining every day, still keep away the generation of unavoidable tartar, find by analysis, this also is because a this existence with glue of biological nature is arranged, it can be in the short period of time of people's feed, penetrate tooth uranium surface and enter into tooth under the suitable especially condition of temperature, the humidity in oral cavity, volumetric expansion has formed firm, not segregative tartar.Analyze thus and associate, if with this biology, may penetrate in other material and go, and the glue that is closely linked with it applies in the building decoration field, will cause the building materials revolution and the building revolution in a unprecedented step.

The purpose of this invention is to provide a kind of added the vegetable fibrin veneer, have high strength, impervious can the preparation method of gypsum brick.

Another object of the present invention provides a kind of product that adopts aforesaid method to make.

The preparation method of gypsum brick of the present invention comprise plant expressed juice removed slag after, at 25-30 ℃ of following constant temperature culture 10-20 days, it was stand-by to obtain nutrient solution; Grain is ground to form 580-650 purpose powder, carry out water treatment and obtain gluten; Above-mentioned plant culturing liquid is mixed with gluten, after stirring, in 31-34 ℃ moist constant temperature, cultivate, obtain the vegetable fibrin veneer after 5-10 days; The vegetable fibrin veneer of 0.005-0.015 part is mixed with the gypsum of 95-100 part, and the water that adds total amount 50% stirs, drop in the stock mould, under 20-23 ℃ the temperature, depanning gets final product behind the 10-18 minute.

Wherein, described plant can comprise vegetables, fruit; Described gypsum is the plaster of Paris for building.

The described vegetable fibrin veneer that obtains is a kind of natural polymer polymer of biologically active, can be as the tensio-active agent of phase interface and surface and interface, have extremely strong, adsorptive power, bounding force, diffusive force and seepage force, with after other material contacts, the reaction of the hydration heat of swift and violent diffusion can take place, can be penetrated into the inside of other material, volatilization along with moisture content, produce huge force of cohesion, the material of various unlike materials is linked together securely, form an integral body, increased the intensity of material greatly, rigidity, fracture toughness and density, because the density on surface is strengthened, and has reduced water-retaining capacity, thereby has improved the macro property of material.

The preparation method of gypsum brick of the present invention is scientific and reasonable, need not in the moulding process to pressurize, heat can be because of changing, but so both reductions of erection time, reduced again pressurize, the consumption of other required energy when heating, and products made thereby is a light material, have do not seep water, thermal insulation, prevent fires, have no side effect, characteristic such as pollution-free, can substitute common brick fully, therefore on same basis, increase floor, can reduce cost with this gypsum brick, economize the land resource, increase economic efficiency.

Performance Detection through national building materials test center, this gypsum brick all reach the standard of national like product, as table 1:
