Abstract
The invention provides a spraying process of a road coating material, which is characterized by comprising the following steps: s1, preprocessing: cleaning the road surface; s2, selecting a primer: mixing the paint and the diluent according to the weight ratio of 5-6:1-1.2 to obtain a primer; s3, spraying primer on the road surface by using movable spraying equipment; s4, preparing an energy-storage self-luminous coating material; s5, after the primer is dried, spraying an energy-storage self-luminous coating material on the surface of the primer by using spraying equipment, and naturally drying; the amount of the sprayed energy-storage self-luminous coating material is 180-2(ii) a The spraying process provided by the invention is simple and convenient, the energy consumption is low, the prepared coating film layer has good adhesion on the surface of a road, and meanwhile, the coating film layer has good flatness, impact strength and higher hardness, and meanwhile, the drying time is short.
Description
Technical Field
The invention relates to the technical field of road spraying processes, in particular to a road coating material spraying process.
Background
In the road marking construction process, the coating process of the solvent type road marking paint is to clean the road surface firstly. Removing sand, water and oil stains. Then drawing lines and lofting. Generally, the coating is finished once before coating. Coating tools such as a marking coater are prepared, and the coating application viscosity, air pressure and other application parameters are adjusted. Road surface obstacles are removed by a pilot vehicle, spraying is carried out by a marking coating machine, a conical road sign is arranged, and dirt such as dust on the road surface is removed by a blower on the marking coating vehicle. And (4) enabling the marking coating machine to advance at a constant speed to enable the thickness of the coating to be uniform and to reach the required thickness, and recovering the tapered road sign after the coating is dried and does not stick to the tire. Secondly, the road marking paint mainly comprises the following components: the one-component self-drying coating is composed of thermoplastic acrylic resin, chlorinated rubber resin, a plasticizer, pigments with various colors, wear-resistant filler, an auxiliary agent, a solvent and the like. Thirdly, the main characteristics of the road marking paint are as follows: the paint film is hard; the weather resistance performance is super-group; the drying performance is fast.
CN105839556A discloses a road marking construction process method, which relates to the technical field of road engineering and comprises the following steps: the road surface is swept, so that the road surface is clean and free of dust, and the dryness of the road surface is ensured; marking a point mark at the position needing the marked line according to the design, spraying primer with the spraying amount of 150-2(ii) a Melting the marking paint by a hot melting kettle, coating the hot melting marking paint within 5-8 minutes after the primer is sprayed, coating two layers of marking paint, drying the first layer of paint, coating the second layer of paint, uniformly spreading glass beads before the second layer of paint is not dried, wherein the spreading amount is 350-500 kg/m-2And naturally drying to form the road marking with the thickness of 2-4.5 mm. Although the invention solves the problem of easy cracking and falling off of the road marking, other properties of the road marking have many problems.
CN109137774A discloses a road marking method, which belongs to the field of road traffic engineering and comprises the following steps: the method comprises the following steps of road surface cleaning, marking line lofting, primer spraying, coating heating dissolution and blade coating operation, wherein a milling process is added in the road surface cleaning step to form a pit groove, and the road surface is leveled by using a bonding material and asphalt concrete, so that the marking line and the road surface are combined more firmly, the flatness of the surface of the marking line is also improved, two layers of coatings are coated in the blade coating operation, microcrystalline ceramic beads are uniformly spread on the first layer of coatings by using a self-weight spreader before the first layer of coatings are not dried, the second layer of coatings is coated after the first layer of coatings are dried, and the microcrystalline ceramic beads are uniformly spread on the second layer of coatings by using the self-weight spreader before the second layer of coatings are not dried. Although the process is simple and the constructed road marking is not easy to crack, the afterglow time of the road marking in the invention is slow in drying, and the paint used in the marking is not uniformly dispersed. Meanwhile, CN104164152B discloses a multifunctional traffic sign coating and a preparation method thereof, wherein the coating mainly comprises the following raw materials: water, a preservative, a defoaming agent, a wetting agent, propylene glycol, alcohol ester dodeca, silicone-acrylic emulsion, colored aluminum-plated powder, noctilucent powder, high-refraction glass beads, a leveling agent and a polyurethane thickener. Therefore, in the spray coating process, the use of the actual energy storage self-luminous coating, the luminescent material has problems of compatibility with the coating material, poor dispersion effect with other components, and poor stability. Therefore, the final effect of the spraying process is also affected to a certain extent by the coating, and the development of a coating with good performance is necessary.
Therefore, the hardness, the impact strength, the afterglow strength and the afterglow time of the road surface in the spraying process, particularly the spraying process on roads have certain improvement space, and other properties of the road marking are also enhanced. Therefore, the novel spraying process of the road marking has high practical significance.
