Embodiment 1

[0017] The non-slip tactile brick includes a base material layer and a fabric layer covering the base material layer. The bottom material layer is made of crushed stone, limestone powder, cement, and water in a weight ratio of 1:1:0.3:0.15; :0.33:0.01:0.08 weight ratio made. Among them, the particle size of gravel is 10mm; the particle size of river sand is 60 mesh. The thickness of the bottom material layer is 4cm, and the thickness of the fabric layer is 1cm.

[0018] The steps of the production method of the non-slip tactile brick are as follows: add river sand, pitch-based carbon fiber, cement and pigment into a mixer, add water and mix evenly to obtain a fabric; add gravel, limestone powder and cement into a mixer, add water and mix evenly to obtain a bottom Material; the fabric is pressed on the bottom material by vibration and pressure, and it can be air-dried after pressing and forming. Wherein, the pressure of vibration pressurization is 2 MPa.

Embodiment 2

[0020] The non-slip tactile brick includes a base material layer and a fabric layer covering the base material layer. The primer layer is made of crushed stone, limestone powder, cement, and water in a weight ratio of 0.5:1.5:0.5:0.05; :0.2:0.02:0.25 weight ratio made. Among them, the particle size of gravel is 5mm; the particle size of river sand is 50 mesh. The thickness of the bottom material layer is 10cm, and the thickness of the fabric layer is 0.2cm.

[0021] The steps of the production method of the non-slip tactile brick are as follows: add river sand, pitch-based carbon fiber, cement and pigment into a mixer, add water and mix evenly to obtain a fabric; add gravel, limestone powder and cement into a mixer, add water and mix evenly to obtain a bottom Material; the fabric is pressed on the bottom material by vibration and pressure, and it can be air-dried after pressing and forming. Among them, the pressure of vibration pressurization is preferably 0.8 MPa.

Embodiment 3

[0023] The non-slip tactile brick includes a base material layer and a fabric layer covering the base material layer. The bottom material layer is made of crushed stone, limestone powder, cement, and water in a weight ratio of 1:2.5:0.1:0.15; :0.35:0.05:0.05 weight ratio made. Among them, the particle size of gravel is 10mm; the particle size of river sand is 100 mesh. The thickness of the bottom material layer is 2cm, and the thickness of the fabric layer is 1cm.

[0024] The steps of the production method of the non-slip tactile brick are as follows: add river sand, pitch-based carbon fiber, cement and pigment into a mixer, add water and mix evenly to obtain a fabric; add gravel, limestone powder and cement into a mixer, add water and mix evenly to obtain a bottom Material; the fabric is pressed on the bottom material by vibration and pressure, and it can be air-dried after pressing and forming. Among them, the pressure of vibration pressurization is preferably 1.2 MPa. ...

Abstract

The invention relates to an anti-skid blind sidewalk brick and a preparation method thereof. The anti-skid blind sidewalk brick comprises a backing material layer and a fabric layer covering the backing material layer. The backing material layer is composed of gravel, limestone powder, cement and water in the weight ratio of (0.5-2.5):(0.5-2.5):(0.1-0.5):(0.05-0.25); the fabric layer is composed of river sand, asphalt-based carbon fiber, cement, pigments and water in the weight ratio of (0.5-2.5):(0.05-0.25):(0.2-0.5):(0.005-0.05):(0.05-0.25). During preparation, the river sand, the asphalt-based carbon fiber, the cement and the pigments are added into a stirrer, and water is added and uniformly stirred to obtain a fabric; the gravel, the limestone powder and the cement are added into thestirrer, water is added, and the mixture is uniformly stirred to obtain a backing material; a vibration pressurizing mode is utilized to press the fabric on the backing material, and the fabric is dried after being formed. The anti-skid blind sidewalk brick is low in preparation cost and simple in preparation process, the strength of the prepared blind sidewalk brick is high, the anti-skid performance is good, and the blind sidewalk brick is attractive and elegant.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-slip tactile brick and a manufacturing method thereof. Background technique [0002] Blind pavement is a convenient road facility for blind people to travel safely. Generally, it is paved with three types of bricks, one is strip-shaped guiding bricks to guide blind people to move forward with confidence; the other is reminder bricks with dots to remind blind people that there are obstacles ahead; the other is blind road danger warning guiding bricks, The dots are larger. Many existing tactile paving bricks use high-quality natural rubber and synthetic rubber as the base material, together with filling materials and pigments without heavy metals, which often have super anti-skid performance, excellent noise reduction performance, long service life and Rich color choices. But this also inevitably increases the preparation cost of tactile paving brick, is unfav...
