Embodiment 1

[0043] 1. Preparation method of water filtering functional layer material

[0044] Put 500g of coated sand in JJ-5 cement mortar mixer and stir, use 25g of hexanediol diglycidyl ether as adhesive, and 7.5g of supporting polyetheramine modified isophorone diamine as curing agent, 0.6g polypropylene fiber (1cm), 4g inorganic pigment iron oxide red (Tianjin Bodi Chemical Industry Co., Ltd.), obtain the water filtering functional layer material after fully stirring, stand-by.

[0045] 2. Preparation method of water-permeable functional layer material

[0046] Put 2000g basalt gravel (3-8mm continuous gradation), 500g ordinary portland cement PO42.5, 2g basalt fiber chopped strands (4cm), 140g water, 5.28g polycarboxylate high-performance water reducing agent, put in Stir in a JJ-5 cement mortar mixer, and get the permeable functional layer material after fully stirring, ready for use.

Embodiment 2

[0050] 1. Preparation and method of water filtering functional layer material

[0051] Same as Example 1

[0052] 2. Preparation and method of water-permeable functional layer materials

[0053] Same as Example 1

[0054] 3. Preparation and method of filter functional materials

[0055] The water-filtering and water-permeable composite material is prepared by static pressure molding. The water-filtering functional layer material is first placed in a stainless steel mold (200*100*50mm), and the universal press is turned on to apply a pressure of 1.5MPa. After 5 minutes, lift the pressure head . Then add the water-permeable functional layer material into the mold, continue to apply a pressure of 2 MPa for 10 minutes, turn over the mold and the uncured composite material together after 2 hours, and cure and form at room temperature without special maintenance. After 24 hours, the mold is demoulded to obtain a filter functional material with a microporous filter surface layer ...

[0057] 1. Preparation and method of water filtering functional layer material

[0058] Same as Example 1

[0059] 2. Preparation and method of water-permeable functional layer materials

[0060] Same as Example 1

[0061] 3. Preparation and method of filter functional materials

[0062] The water-filtering and permeable composite material is prepared by combining vibration molding and static pressure molding. The water-filtering functional layer material is first placed in a stainless steel mold (200*100*50mm), and then the water-permeable surface layer material is added to the mold to open the concrete. The vibrating table vibrates, and at the same time, the universal press is turned on to apply a pressure of 1.5MPa for 45s. After 2 hours, the mold and the uncured composite material are turned over together, and no special maintenance is required for curing at room temperature. After demoulding after 24 hours, the filter functional material of the microporous filter surfa...

Abstract

The invention relates to the technical field of environmental functional materials, and discloses a preparation method of a sand-based material with a rapid water-filtering function, including a water-filtering functional layer and a water-permeable functional layer. Organic and inorganic fibers with good reinforcement and toughness are bonded with organic and inorganic adhesives respectively, and made into different structures through appropriate fabric order and molding methods, with fast water filtration and filtration of water permeable functional layers Functional material; the invention solves the problem of poor water filtration or water permeability and low strength of a single material; it adopts room temperature curing molding to overcome the defects of high energy consumption and large environmental pollution of the traditional sintering process. The sand-based material with fast water filtering function and the preparation method provided by the invention have simple operation, various structures, no need for high-temperature sintering, easy implementation, and are beneficial to industrialization popularization and application.

Description

technical field [0001] The invention relates to the technical field of environmental functional materials, in particular to a preparation method of a sand-based material with a fast water filtering function. Background technique [0002] Rapid water filtration and permeable materials have important application value in municipal, construction, waste water treatment and other fields. For example, in the municipal construction of urban roads and squares, the laying of rapid filtration and permeable pavement materials is of great significance to the storage of road water and the construction of sponge city systems. [0003] At present, the commonly used pavement rainwater permeable materials mainly include concrete permeable materials, ceramic permeable materials, polymer permeable materials, sand-based permeable materials and composite water filter materials of the above materials. These existing permeable materials all have some disadvantages, such as large pores between agg...
