Novel stone-like ecological water permeable brick and preparation method thereof

Abstract

The invention relates to a novel stone-like ecological water permeable brick and a preparation method thereof. The novel stone-like ecological water permeable brick comprises a brick body with the surface coated with a stone-like coating. The brick body comprises the following raw materials in parts by weight: 50-60 parts of aggregate, 15-18 parts of polypropylene, 7-8 parts of unsaturated polyester resin, 1-2 parts of a cross-linking agent, 6-8 parts of ceramic waste, 4-5 parts of waste glass, 1-2 parts of fly ash, 3-4 parts of diatomite, 1-2 parts of an adhesive and 10-15 parts of water. The preparation method comprises the following steps of: S1, preparing a mixture; S2, forming a brick body; and S3, spraying a stone-like coating; The novel stone-like ecological water permeable brick has the following advantages and effects: the addition of the waste glass promotes the improvement of porosity and improves the water permeability; a continuous structural framework can be formed between the aggregate and the ceramic waste through a mixture doped with both fly ash and diatomite, so that the compactness is improved; and the adhesive improves the bonding strength of a cross-linked product with higher structural strength obtained by cross-linking the polypropylene and the unsaturated polyester resin, and the aggregate and other raw material components, so that the compressive strength of the water permeable brick is effectively enhanced.

Description

technical field [0001] The present application relates to the technical field of permeable bricks, in particular to a novel stone-like ecological permeable brick and a preparation method thereof. Background technique [0002] In order to maintain the balance of the ecological environment, the state has vigorously promoted the construction of "sponge city" in recent years, and permeable pavement is one of the key technologies for the construction of "sponge city". Permeable pavement can effectively reduce the risk of urban waterlogging, alleviate urban water resource stress and various ecological problems such as heat island effect and rain island effect, and permeable bricks are widely used as one of the key products of permeable pavement; imitation stone permeable bricks, in While having the basic functions of permeable bricks, it also has an appearance similar to natural stone, so it is favored by more and more consumers. [0003] There are many types of permeable bricks ...

Problems solved by technology

[0003] There are many types of permeable bricks produced in the market, with different shapes and great quality differences. Some of them have insufficient compressive strength and are prone to damage during long-term use, so there is still room for improvement
