preparation example Construction

[0039] The preparation process of the adhesive is as follows: stirring the solvent-free epoxy resin, adding the solvent-free epoxy curing agent at the same time, continuing to stir until the mixture is uniform, and then aging for 15-30 minutes.

[0040] Alternatively, the preparation process of the adhesive is as follows: stirring the polymer polyol, adding the solvent-free polyurethane curing agent at the same time, continuing to stir until the mixture is uniform, and aging for 15-30 minutes.

[0041] The method also includes the steps of:

[0042] In the floor tile mould, the lower part whose thickness accounts for 4 / 5 uses the sand that is uniformly mixed and contains a mixture of solvent-free epoxy resin and solvent-free epoxy curing agent as an adhesive, and the thickness accounts for 1 / 5. The upper part adopts sand that is uniformly mixed and contains a mixture of polymer polyol and solvent-free polyurethane curing agent as an adhesive.

Embodiment 1

[0045] According to weight percentage: 3-6 parts, 1.5-3 parts of solvent-free epoxy curing agent, 91-95.5 parts of dust-free high-hardness sand with a particle size of 1-3mm, weighed well;

[0046] Slowly add solvent-free epoxy curing agent to solvent-free epoxy resin under stirring, and mature for 15-30min;

[0047] While stirring the sand, spray the mixed adhesive at the same time and stir evenly;

[0048] Take the evenly mixed sand containing adhesive and pour it into the floor tile mould;

[0049] In the floor tile mould, the uniformly mixed sand containing the adhesive is compacted and flattened until it is solidified and formed, and then demolded.

Embodiment 2

[0051]According to weight percentage: 2-5 parts of solvent-free epoxy resin, 1-2.5 parts of solvent-free epoxy curing agent, 92.5-97 parts of 4-6mm dust-free high-hardness sand, weighed well;

[0052] Slowly add solvent-free epoxy curing agent to solvent-free epoxy resin under stirring, and mature for 15-30min;

[0053] While stirring the sand, spray the mixed adhesive at the same time and stir evenly;

[0054] Take the evenly mixed sand containing adhesive and pour it into the floor tile mould;

[0055] In the floor tile mould, the uniformly mixed sand containing the adhesive is compacted and flattened until it is solidified and formed, and then demolded.

Abstract

The invention discloses a permeable terrace brick manufacturing method. The method comprises the steps of weighing sands with different particle sizes and different proportions; stirring the weighed sand, spraying mixed adhesives, and conducting stirring continuously till the adhesives are evenly mixed with the sand; pouring the sand which is obtained after even mixing and contains the adhesives into a floor tile mold, compacting the sand to be flat till solidification, and conducting demolding. Terrace bricks manufactured with the method are light and high in crush resistance, bending resistance and abrasion resistance, and rainwater can permeate through the terrace bricks quickly.

Description

technical field [0001] The invention relates to a preparation method of permeable floor tiles. Background technique [0002] In recent years, most of the cities have been covered by concrete, and rainwater cannot penetrate the ground and can only be drained from the sewers. Many cities have experienced waterlogging during heavy rains, affecting people's normal travel. The invention aims to solve the problem that the surface of existing outdoor solid bricks, marbles, cement floors, chemical floors and the like is highly sealed, making it difficult for water brought by rainfall to infiltrate and quickly form surface runoff. If it is a heavy rainstorm or a heavy rainstorm, the accumulated surface runoff will affect the normal traffic due to the small rainwater outlet and poor drainage, and may even cause urban waterlogging and bring more derivative problems. High permeable floor tiles are floor tiles with a microporous structure (porosity above 30%). Rainwater can quickly pene...
