Abstract

The invention relates to the technical field of pavement bricks, and provides a preparation method of a composite layer pavement brick. The preparation method comprises the following steps: preparinga surface layer material by adopting a vacuum pressing method, preparing a bottom layer material by adopting a vacuum exhausting method, and connecting a bottom layer and a surface layer by adopting aconnecting layer containing gravels to increase the interface bonding force of the surface layer and the bottom layer and improve the bearing capacity of the composite layer pavement brick; and carrying out low-temperature curing treatment on the composite layer material to complete demolding, and then treating the surface of the surface layer by adopting a shot blasting treatment technology to form surfaces with different concavities and convexity. The preparation method is simple and excellent, the combination degree of the surface layer and the stratum can be improved, and it is guaranteedthat the surface layer material and the bottom layer material are not prone to falling off; and the contractibility of the material is reduced, so that the composite layer pavement brick material ishigh in bearing capacity, good in skid resistance, good in durability, low in overall manufacturing cost and suitable for wide application.

Description

technical field [0001] The application belongs to the technical field of pavement bricks, and in particular relates to a preparation method and application of composite layer pavement bricks. Background technique [0002] Pavement bricks are a common type of brick in my country, also known as pavement bricks, which are usually widely used in sidewalks, residential areas, and squares. It is made of cement, gravel, and sand as raw materials. It is shaped by vibration, and the surface is cut into stripes or squares. It looks like granite. Some are elegant and rough, and some are romantic and soft. [0003] The production of concrete pavement bricks also has a certain history. The early concrete pavement bricks were relatively thin, and their strength, wear resistance and flexural resistance were relatively low, so their service life was short. The concrete pavement bricks used in some cities in our country are poured with plastic molds. Although this kind of pavement bricks ar...
