[0003] When the existing permeable bricks are actually transported or laid, their sides are often bumped, and they are prone to collapse or delamination defects after bumping, which makes the permeable bricks unusable, causing a lot of waste, and is not environmentally friendly. At this time, the permeable bricks have poor ability to degrade or infiltrate oil stains, and the residue of oil stains will become a food source for bacteria or fungi, causing microorganisms to multiply in the bricks, and moss is easy to grow, which will greatly affect the permeable effect of permeable bricks

preparation example Construction
[0024] A method for preparing a fire-free permeable brick that can quickly remove oil stains, comprising the following steps:
[0025] A. Preparation of binder: Weigh the components according to the following mass percentages: 8-10% tetraethyl orthosilicate, 55-65% epoxy resin, 20-25% absolute ethanol, 5-10% % butanol, 0.05-2% active substance, mixed and stirred to dissolve to obtain binder;
[0026] B. Weigh the components according to the following mass percentages: 60-70% barren granules, 5-10% cement and 20-30% binder, mix and stir evenly to obtain the mixture;
[0027] C. Pour the mixed material into the forming mold for pressing, place it on a vibrating table to vibrate, make the mixed material spread flat on the bottom of the forming mold, and naturally consolidate and maintain it at room temperature to obtain unfired permeable bricks. Such as figure 1 shown.
[0028] Use a binder containing oleophobic and hydrophobic properties as the binder of unfired permeable bri...
Embodiment
[0030] The permeable bricks of the prior art and the permeable bricks prepared by the present application were used for the oil stain removal experiment. The quantitative oil stains were poured on the brick surface and washed with water or cleaning agent and water. The washing time and water consumption are shown in Table 1 below.
[0031]
[0032] Table 1
[0033] It can be seen from Table 1 that the permeable bricks prepared by the present application can remove oil stains more quickly due to the internal oleophobic and hydrophobic passages, and the water consumption is greatly reduced, and the water consumption is significantly reduced.
[0034] To further illustrate, the components of the binder in step A also include 5-8% zinc acetate and 5-8% photocatalyst powder. Using photocatalyst oil to decompose, combined with the synergistic effect of zinc acetate, the photolysis reaction of photocatalyst powder occurs faster, so that the permeable brick has the water permeabili...

Abstract
The invention relates to a preparation method for baking-free water-permeable bricks capable of rapidly removing oil stains. The method comprises the following steps: A. preparing a binder: weighing the following ingredients in percentage by mass: 8% to 10% of tetraethyl orthosilicate, 55% to 65% of epoxy resin, 20% to 25% of anhydrous ethanol, 5% to 10% of butanol and 0.05% to 2% of active substance, and carrying out mixing, stirring and dissolving, so as to obtain the binder; B. proportionally weighing ingredients of a mixture, carrying out mixing, and then, carrying out uniform stirring, so as to obtain the mixture; and C. carrying out forming pressing, carrying out natural solidifying at normal temperature, and carrying out curing, thereby obtaining the baking-free water-permeable bricks. According to the baking-free water-permeable bricks capable of rapidly removing the oil stains and the preparation method for the baking-free water-permeable bricks, provided by the invention, the binder with oleophobic and hydrophobic performance serves as the binder of the baking-free water-permeable bricks, so that oleophobic and hydrophobic channels can be formed among sterile granules, even if the oil stains are poured onto brick surfaces, the oil stains can be rapidly discharged through the oleophobic and hydrophobic channels inside the water-permeable bricks by using water or a detergent, the oil stains cannot stay on the internal channels of the water-permeable bricks, and thus, the deoiling speed is greatly increased.
Description
technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a fire-free permeable brick capable of quickly removing oil stains and a preparation method thereof. Background technique [0002] At present, in cities, it is often necessary to lay pavement bricks in municipal projects such as sidewalks, community pavements, pedestrian streets, and the bottom of buildings. Commonly used pavement bricks include marble, ceramic tiles, glazed bricks, and cement bricks. However, due to the low water permeability of the above-mentioned types of pavement bricks, the use of large areas makes it difficult for rainwater to penetrate into the ground, destroying the underground micro-environment, often causing problems such as groundwater level drop, ground subsidence, and vegetation survival difficulties. Weather, the ground is prone to water accumulation, affecting traffic. Therefore, in recent years, permeable bricks have been developed, and ...
