Embodiment 1

[0017] refer to figure 1 The present invention was made. The PVC curbstone is characterized in that: it includes a PVC rectangular body 1, and convex edges 3 are fixed on both sides of the bottom of the PVC rectangular body 1, and the convex edges 3 are arranged along the axis direction of the PVC rectangular body 1. During construction, the convex edges 3 The edge 3 is buried below the ground, and the soil above the convex edge 3 is laminated on the convex edge 3 to ensure the overall stability. There is a weight reduction hole 2 inside the PVC rectangular body 1, and the axis of the weight reduction hole 2 is connected to the PVC rectangular body. The axes of 1 are set parallel.

[0018] The weight reduction holes 2 are provided with 4-8. When there are eight weight-reducing holes 2, they are arranged in four rows and two columns, and the dimensions of each weight-reducing hole 2 are: 50 mm in height and 60 mm in width.

[0019] The cross-sectional dimensions of the PVC r...

Embodiment 2

[0028] A production method of PVC curbstone, characterized in that: it comprises the following steps:

[0029] (1) The PVC recycled material is crushed by a crusher, then pulverized by a pulverizer, and passed through an 80-mesh sieve to obtain a PVC grinding powder for use; the PVC recycled material is the recycling of PVC profiles, PVC pipes, and PVC scraps thing;

[0030] (2) Weigh the following raw materials by mass percentage: PVC abrasive 27%; calcium carbonate 60%; composite stabilizer 5%; lubricant 0.7%; impact modifier 4.4%; UV absorber 0.9%; Plasticizer 2%;

[0031] (3) Mixing: add the raw materials in step (2) into a high-speed mixer, mix and stir to 120°C, then pour into a cold mixer for stirring and cooling, and when the temperature drops below 50°C, it becomes a mixture;

[0032] (4) Extrusion molding: add the mixture to a twin-screw extruder, heat and plasticize, control the temperature at 160°C-185°C, and then feed it to the die of the die for extrusion, and ...

Embodiment 3

[0035] A production method of PVC curbstone, characterized in that: it comprises the following steps:

[0036] (1) The PVC recycled material is crushed by a crusher, then pulverized by a pulverizer, and passed through a 100-mesh sieve to obtain a PVC grinding powder for use; the PVC recycled material is the recycling of PVC profiles, PVC pipes, and PVC scraps thing;

[0037] (2) Weigh the following raw materials by mass percentage: PVC abrasive 24%; calcium carbonate 63%; composite stabilizer 3%; lubricant 0.6%; impact modifier 5%; UV absorber 0.8%; Plasticizer 3.6%;

[0038] (3) Mixing: add the raw materials in step (2) into a high-speed mixer, mix and stir to 120°C, then pour into a cold mixer for stirring and cooling, and when the temperature drops below 50°C, it becomes a mixture;

[0039] (4) Extrusion molding: add the mixture to a twin-screw extruder, heat and plasticize, control the temperature at 160°C-185°C, and then feed it to the die of the die for extrusion, and ...

Abstract

The invention discloses a PVC road traffic stone and a production method thereof. The PVC road traffic stone comprises a PVC rectangular body, protruding edges are fixed at two sides of the bottom ofthe PVC rectangular body, the protruding edges are arranged along the axial direction of the PVC rectangular body, weight reducing holes are arranged in the PVC rectangular body, and the axis of everyweight reducing hole is parallel to the axis of the PVC rectangular body. The production method comprises the following steps: crushing and milling recovered PVC; weighing, by mass, 24-30% of the obtained milled PVC, 58-63% of calcium carbonate, 3-5% of a composite stabilizer, 0.5-0.7% of a lubricant, 3-5% of an impact modifier, 0.8-1% of an ultraviolet absorber and 2-4% of a plasticizer; mixingabove weighted raw materials; and adding the obtained mixture into a double screw extruder, and performing extrusion forming. The PVC road traffic stone is easy and fast to mount; and the PVC road traffic stone is produced from the recovered PVC, so the PVC road traffic stone has the advantages of good impact resistance, unbreakability, convenience in replacement and maintenance, reduction of thelabor intensity, and improvement of the construction efficiency.

Description

technical field [0001] The invention relates to an improvement of a curbstone, in particular to a PVC curbstone and a production method thereof. Background technique [0002] At present, both sides of the road and the surrounding of the green belt are divided by curb stones. The traditional curb stones are generally made of concrete or marble. The concrete curb stones are made by off-site prefabrication. Marble curbs are made of rough cut and polished surfaces. Its shortcomings are: the weight is too heavy, it is inconvenient to carry, the length of each roadside stone is short, and the installation is difficult; due to its hard material, it is prone to breakage after being hit or during transportation, and replacement and maintenance are relatively difficult. Difficult, the construction is labor-intensive, time-consuming and labor-intensive, and the construction efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a PVC...
