[0059] Recycled PE plastic particles 1.0~2.5,

[0060] Glass beads 20.0~22.0,

[0061] Titanium dioxide 3.0~5.0,

[0062] Quartz sand 9.0~11.0

[0063] Light calcium carbonate powder 15.0~17.0,

[0064] Heavy calcium carbonate 24.0~26.0,

[0065] Polyethylene wax 0.5~1.0,

[0066] EVA resin 0.5~1.0,

[0067] Dioctyl phthalate 0.5~1.0,

[0068] Other additives 1.0~1.2,

[0069] This example is a hot-melt white reflective marking paint. The production process is attached figure 1 The recommended heating temperature in the tank during construction is 180-200°C, and the required temperature is slightly lower than that of ordinary hot-melt road m...

specific Embodiment 3

[0070]The difference between this embodiment and the second embodiment is that the energy-saving hot-melt road marking paint is prepared from the following raw materials, and the weight ratio of the raw materials is:

[0071] Recycled EPS plastic particles 14.5~15.5,

[0072] Acrylic resin 13.5~17.0,

[0073] Recycled PP plastic particles 4.5~5.5,

[0074] Recycled PE plastic particles 6.5~8.5,

[0075] Recycled PVC plastic particles 1.5-2.0,

[0076] Glass beads 21.0~22.0,

[0077] Titanium dioxide 3.5 ~ 4.5,

[0078] Quartz sand 9.0~11.0

[0079] Light calcium carbonate powder 15.0~17.0,

[0080] Heavy calcium carbonate 26.0~28.0,

[0081] Polyethylene wax 0.5~1.0,

[0082] EVA resin 3.5~4.0,

[0083] Lithopone 1.0~2.0,

[0084] Dioctyl phthalate 0.5~1.0,

[0085] Other additives 1.8~2.5,

[0086] This example is a hot-melt white rainy night reflective oscillating marking paint, and its manufacturing method and construction method are basically the same as those ...

specific Embodiment 4

[0087] The difference between this embodiment and specific embodiments one, two, and three is that the heavy calcium carbonate of 11% to 16% by weight is subtracted from the raw material, and cadmium yellow pigment of 11% to 16% by weight of the raw material is added to make a yellow color coating. Other raw material proportioning, manufacturing method and construction method are basically the same as embodiment one, two, three.

Abstract

The invention discloses a heat-fusing road mark coating made from waste plastic and a preparation method thereof, relating to a chemistry coating and a preparation method thereof, in particular to a coating used for road traffic safety mark and a preparation method thereof. The invention is characterized in that: the heat-fusing road mark comprises the following materials by weight: 5.0 to 20.0 proportions of regeneration waste plastic particle, 3.0 to 10.0 proportions of C5 petroleum resin, 0.5 to 13.0 proportions of acrylic resin, 3.0 to 5.0 proportions of titanium pigment, 9.0 to 14.5 proportions of quartz sand, 15.0 to 27.0 proportions of light calcium carbonate powder, 24.0 to 28.0 proportions of heavy calcium carbonate powder, 0.5 to 1.0 proportion of polyethylene wax, 0.5 to 4.0 resin EVA, 20.0 to 22.0 glass micro-beads, 0.5 to 1.0 proportion of dioctyl phthalate and 1.0 to 2.5 proportions of other additives. The preparation method has following steps: (1) classifying and grinding waste plastic, (2) adding materials according to prescription, (3) adding additive and evenly mixing. The invention solves the problems of high cost, large energy consumption of the traditional heat-fusing road mark coating, also provides a new method of directly utilizing waste plastic, which finds a new way for saving energy and eliminating 'white pollution'.

Description

Technical field: [0001] The invention belongs to the technical field of chemical coatings and relates to recycling of waste plastics, in particular to a method for producing road marking paint by using waste plastics. Background technique: [0002] Hot-melt road marking paint is a kind of road safety marking paint that was gradually promoted and used in the world in the late 1960s. During the construction of hot-melt road marking paint, the powdery paint is melted by heating, and then used The equipment is applied on the ground and becomes a distinctive marking line after condensation. Because hot-melt coatings have the characteristics of super-fast drying, high durability and strong wear resistance, and night reflection, currently domestic first-class roads and expressways basically use hot-melt road marking coatings. [0003] At present, there are still some disadvantages in hot-melt road marking paints: First, the coating film of hot-melt coatings is much thicker than th...
