Problems solved by technology

[0007] The above-mentioned first and second kinds of production process of colored pavement materials are complex and costly, and the color of colored pavement materials is not bright enough and not durable enough; Simple, colorful and long-lasting
However, this kind of pavement material is often different from the basic pavement material, and when the temperature changes greatly, there will be pavement damage caused by different expansions.

Embodiment 1

[0069] The mold of the road surface combination pasting block of the present embodiment is provided with nine mold cores 4 arranged in 3 rows and 3 columns, and the mold holes 5 and the mold cores 4 are circular in shape. The orifice area of ​​die hole 5 is 80cm 2 , the thickness of the template 1 is 30 mm, the length of the core 4 extending into the die hole 5 is 10 mm, and the distance between two adjacent die holes 5 is 2 mm. The template 1, the bottom plate 2 and the spliced ​​frame plate 3 are square in shape. The spliced ​​frame plate 3 is formed by splicing end to end of four rectangular slats, and the spliced ​​frame plate 3 is in the shape of a hollow frame plate. See above for other structures.

Embodiment 6

[0075] Add 10kg of alumina powder, 0.75kg of calcium carbonate powder, and 0.1kg of dye (iron oxide red) to 20kg of water, ball mill for 4 hours to obtain the first slurry, and then add the first slurry to 200kg of alginic acid with a concentration of 1.5wt%. In the sodium solution, stir evenly to form the second slurry with a solid phase content of 4.7%, wherein the solid phase content in the second slurry=solid phase powder mass / gross slurry weight, solid phase powder mass=alumina powder mass + mass of calcium carbonate powder + mass of dyestuff, total weight of slurry = mass of solid phase powder + mass of sodium alginate solution.

[0076] Add 2.5 kg of gluconolactone powder into the second slurry, then stir evenly, and let stand at 40° C. for 48 hours to obtain the first gel. Among them, due to the slow outflow of H from the outlet of gluconolactone powder + Therefore, there is no obvious gel phenomenon during the stirring process, and the gel is gradually formed only du...

Abstract

The invention discloses a method and mould for preparing a pavement combined adhering block. The mould comprises a template, a plurality of mould cores, a fixed plate, a bottom plate and a detachable assembled frame plate; the template is located above the fixed plate, a plurality of through mould holes are formed in the template, one ends of the mould cores are formed in the fixed plate while the other ends extend into the mould holes; the assembled frame plate is mounted between the template and the bottom plate, the distance between the template and the bottom plate is greater than or equal to the thickness of a to-be-processed combined adhering block, and the lengths of the mould cores in the mould hole extending directions thereof are greater than or equal to the thickness of the template. The mould can prepare a plurality of brick blocks at one time and the brick blocks are connected as a whole through a linking layer, so that the pavement combined adhering block is obtained. As two adjacent brick blocks are separated from a certain distance, pavement damage caused by thermal expansion can be avoided.

Description

technical field [0001] The invention relates to a method for preparing a combined pavement pasting block. Background technique [0002] Colored pavement has the functions of beautifying the environment and warning traffic. Colored pavement is widely used in Europe to remind road users which part of the road can be used at which time. Colored pavement is widely used in Europe to provide a separate lane for special road users, such as bus lanes dedicated to public transport, bicycle lanes, small motor lanes, electronic toll booths dedicated to emergency services and VIP card holders Lane. Colored roads are distinguished by color on some speed bumps. This distinction is very useful. It can effectively reduce traffic violations and increase traffic safety. In addition, the popularization of colored pavement can greatly change the image of the city and reflect the characteristics of the city. Not only reflected in the changes in the appearance of the city, but also in the c...
