[0018] This example is used to illustrate the preparation method of the sand-based permeable brick provided by the present invention.

[0019] Add 0.5 parts by weight of ethanol in 5 parts by weight of bisphenol A epoxy resin (purchased from Zibo Shaohua Industry and Trade Co., Ltd., epoxy value 0.09-0.14mol / 100g), mix well, add 0.6 parts by weight of ethylenediamine to obtain glue. Then, the glue solution was added to 100 parts by weight of silica sand with an average particle diameter of 0.6 mm and mixed uniformly. Pour the resulting mixture into a steel mold with a size of 100×200×45 mm, using a hydraulic press model YAW4605 (purchased from Shanghai Xinsansi Measuring Instrument Manufacturing Co., Ltd.), at 20°C, apply 3000N / cm 2 The pressure is pressed for 1 minute, and then the pressure is released to obtain a sand-based permeable brick prefabricated part.

Abstract

The invention provides a method for preparing a sand-base water-permeable brick. The method comprises the following steps: preparing a prefabricated part of the sand-base water-permeable brick and performing microwave solidification on the prefabricated part of the sand-base water-permeable brick, wherein the condition of the microwave solidification comprises solidifying temperature at 80-150 DEG C and solidifying time being 3-20 minutes. According to the method, the solidifying time is greatly shortened and the pressure resistance and water permeability of the sand-base water-permeable brick are obviously increased.

Description

technical field [0001] The invention relates to a preparation method of a sand-based permeable brick. Background technique [0002] At present, cement, asphalt, marble and other non-permeable materials are mostly used in urban construction to pave the ground. These hardened pavements make it difficult to exchange heat and moisture between the ground surface and the air, and the ability to naturally adjust the temperature and humidity of the urban ground is very poor, and the surface absorbs heat. Difficulties, resulting in a large amount of waste heat in the urban space, and a large amount of reflection on the ground to radiate solar heat, which leads to the phenomenon that the nighttime temperature in the city is higher than that in the suburbs. Moreover, in rainy days, the hardened pavement will prevent rainwater from infiltrating directly into the ground, causing water to accumulate everywhere, affecting the comfort and safety of the road. The healthy growth of surface v...
