Embodiment 1

[0028] This embodiment provides a method for preparing wear-resistant reflective sand, wherein the wear-resistant reflective sand is composed of white quartz sand or white corundum sand coated with epoxy resin high temperature curing system glue and glass reflective microbeads. The epoxy resin high temperature curing system glue solution is composed of epoxy resin, curing agent and pigment;

[0029] Wear-resistant reflective sand is prepared through the following steps:

[0030] Step 1: Add a curing agent to the epoxy resin, stir evenly, after pre-reacting at 100-110°C for 1 hour, add pigments and mix evenly, and then defoam to obtain an epoxy resin high-temperature curing system glue;

[0031] Step 2: Weigh the glue of epoxy resin high temperature curing system, put it into white corundum or white quartz sand that has been preheated to 90~100℃, stir evenly, and then add glass reflective beads with a particle size of 0.45~0.5μm , Stir until the white corundum or white quartz sand co...

Embodiment 2

[0037] This embodiment provides a pre-formed reflective material for all-weather roads, including a plate, and the plate is coated with reflective paint;

[0038] The board is pressed by multiple layers of polyester cloth impregnated with epoxy resin and acetone glue;

[0039] The reflective coating includes resin coating, reflective beads and the wear-resistant reflective sand obtained in Example 1;

[0040] The resin coating is one of two-component epoxy resin marking paint, two-component methyl methacrylate marking paint or two-component polyurea marking paint.

[0041] The reflective beads are rainy night marking reflective beads with a particle size of 0.8-1mm and ordinary marking surface-sprinkled glass reflective beads with a particle size of 0.3-0.6mm.

[0042] Reflective beads at rainy night at 200~320g / m 2 Arranged on the board, the ordinary reflective beads are 600~640g / m 2 Arranged on the board.

[0043] The mass ratio formula of epoxy resin and acetone glue is: bisphenol A e...

Embodiment 3

[0047] This embodiment provides a preparation method of a pre-formed reflective material for all-weather roads

[0048] Step 1: Prepare the board

[0049] Step 1.1: Prepare epoxy resin acetone glue according to the proportioning relationship given in Example 2;

[0050] Step 1.2: Immerse the polyester cloth with epoxy resin acetone glue, dry at 100~110℃, control the pre-curing degree at 90-95%, prepare polyester epoxy resin prepreg, superimpose 4~5 layers of polyester ring Oxygen resin pre-impregnated cloth is cured and molded at 90℃ / 1.5h+120℃ / 1h+140℃ / 3h in a thermoforming press to obtain a sheet.

[0051] Step 2: Prepare wear-resistant reflective sand

[0052] The preparation method of wear-resistant reflective sand is the same as the preparation method of wear-resistant reflective sand given in Example 1;

[0053] Step 3: Preparation of reflective material

[0054] Sprinkle the wear-resistant coated sand evenly on the surface of the board prepared in step 1, spray the resin coating eve...

Abstract

The invention discloses a preformed reflection material for all-weather roads. The preformed reflection material comprises a plate, the plate is coated with a reflection coating, the plate is formed through compacting a plurality of terylene clothes dipped with an epoxy resin acetone glue solution, the reflection coating comprises wear-resistant reflection sand, a resin coating and reflection beads, the wear-resistant reflection sand is formed by a white quartz sand or white pulverized corundum coated epoxy resin high temperature curing system and reflection glass beads, and the epoxy resin high temperature solidification system comprises epoxy resin, a curing agent and a pigment. The reflection material compounding the reflection coating with the plate prevents cracking of the reflection coating and meets demands of cutting for forming rainy night markers with different shapes and sizes, and the wear-resistant reflection sand reduces tire wearing caused by rainy night beads and greatly improves the good reflection durability of the rainy night; and the reflection material can be cut to form the rainy night reflection markers with different shapes or different sizes in order to meet the special requirements of local rainy night reflection of roads, can realize refined product in factories, and has a high cost performance.

Description

Technical field [0001] The invention belongs to the technical field of traffic pavement materials, and relates to materials for road markings, in particular to a preformed reflective plate for all-weather roads and a preparation method thereof. Background technique [0002] Whether the road markings are eye-catching, especially under climatic conditions such as rainy days and nights, directly affects the safety of vehicles. However, general road markings become blurred in rainy days or nights, and even have no guiding effect. One way to solve this problem is to use rainy night reflective beads of large particle size, because rainy night reflective beads of large particle size can still show excellent reflective properties in rainy days or nights. However, use such large-particle rainy night reflective beads. Use a two-component marking paint with good bonding properties, otherwise the rainy night reflective beads will easily fall off the marking; in addition, this large-particle ...
