Problems solved by technology

[0005] The solid content of the hot-melt coating is 100%. It is a solvent-free coating made of special synthetic resin as the base material, with pigments, fillers and glass beads. It is heated at 200 ° C and sprayed with mobile machines. Cooling and film formation; the material must use special equipment to heat up the synthetic resin to melt and solidify after construction. It has good wear resistance and weather resistance. The service life can reach 20-36 months, but it consumes a lot of energy when it is melted at high temperature.
[0006] Moreover, the above-mentioned materials are made of organic chemical raw materials such as synthetic resins, initiators, and curing agents. During construction, some toxic and harmful gases will be emitted, which will pollute the environment and endanger health. Special equipment must be equipped during road construction. Comprehensive cost, construction Operation, work intensity, process requirements, and environmental protection are not ideal, and it has a series of shortcomings such as a large amount of harmful substances, large environmental pollution, large health hazards, high energy consumption, easy slipping in rainy days, and difficult recoating construction, especially VOC (Volatile organic compounds) up to 650g / L, a large amount of solvents volatilize, causing immeasurable pollution consequences to the environment

Abstract

The invention relates to the technical field of traffic and in particular relates to a road marking material based on a phosphorus magnesium material and a construction method. The road marking material is composed of a phosphorus magnesium material and glass beads, and comprises the following components in parts by weight: 80-120 parts of magnesium phosphate cement, 2-15 parts of an admixture, 10-15 parts of an additive, 0-5 parts of inorganic pigments and 5-15 parts of glass beads. The construction method comprises the following steps: brushing with an adhesion agent, batching, coating marking, applying the glass beads and curing. The material disclosed by the invention has the advantages of being excellent in penetrating wettability, high in early strength, high in sealing adhesion force, quick-drying, wear-resistant, water-resistant, sun-proof, difficult to skid, convenient in construction, low in cost, easy for re-coating, simple in preparation, energy-saving and energy-saving.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a road marking material based on phosphorus and magnesium materials and a construction method. Background technique [0002] With the development of my country's transportation industry, various road signs have been widely used in various grades of roads and other fields, and play an important role in safe driving. The currently used road marking materials are mainly divided into two types in terms of form: solvent type and hot melt type, and solvent type is divided into normal temperature type and heating type. [0003] The solid content of the room temperature type material is about 79%. Petroleum resin, terpene resin, maleic anhydride resin and polyester are generally used. This kind of coating can be applied by spraying, brushing and roller coating. It is suitable for the outer line of the road with less traffic. And parking lots, etc.; although the material can be co...
