Problems solved by technology

[0003] At present, the domestic application in this respect is still in its infancy, although the water-based epoxy resin system has been successfully applied to colored pavements, such as patent publication number: CN107513335A discloses a kind of outdoor weather-resistant, wear-resistant, stain-resistant, color anti-skid water-based environmental protection coating and Its preparation method is simple and has good overall performance. Compared with other outdoor pavement coatings, it has made great progress, but there are also curing agents with pungent odor, which is not environmentally friendly, and the coating takes a long time to dry and hard to apply in rainy seasons , It is difficult to solidify in winter, and at the same time, the outdoor ultraviolet resistance is not good, the low temperature is brittle, and it is easy to crack.

preparation example Construction

[0021] The invention provides a pavement coating, comprising a first composition and a second composition; the raw material components of the first composition include: 50-100 parts by weight of water-based acrylic modified epoxy resin emulsion, 10-100 parts by weight of ionized water, 1-5 parts by weight of bentonite, 50-100 parts by weight of barium sulfate, 50-150 parts by weight of non-metallic minerals, 200-600 parts by weight of wear-resistant aggregate; wherein, the non-metallic minerals are kaolin and / or diatomite; wear-resistant aggregate is selected from one or more of quartz sand, pottery particles, carborundum and glass sand; the preparation method of water-based acrylic modified epoxy resin emulsion comprises the steps of: injecting epoxy resin into the reaction In the kettle, heat up to 80°C and keep it warm, then inject hydroxyl-containing water-soluble acrylic resin, stir evenly, then slowly add organic amine or ammonia water, stir vigorously, then slowly add l...

Embodiment

[0029] This embodiment provides a pavement coating, including a first composition and a second composition;

[0030] The raw material components of the first composition include by weight: 100 parts by weight of water-based acrylic modified epoxy resin emulsion, 50 parts by weight of deionized water, 1 part by weight of bentonite, 50 parts by weight of barium sulfate, 70 parts by weight of kaolin, 300 parts by weight of quartz sand; wherein, the preparation method of the water-based acrylic modified epoxy resin emulsion comprises the steps of: injecting the epoxy resin into the reactor, heating up to 80°C and keeping it warm, then injecting the hydroxyl-containing water-soluble acrylic resin, stirring evenly, Then slowly add organic amine, stir vigorously and then slowly add liquid epoxy resin. After 20 minutes of vigorous stirring, the liquid changes from pure transparent to pure white. The sample is dropped in pure water, and it quickly disperses into a milky white fine and u...

Abstract

The invention relates to a pavement coating and a preparation method thereof. The pavement coating comprises a first composition and a second composition; the first composition comprises, by weight, the following raw materials: 50-100 parts of aqueous acrylic acid modified epoxy resin emulsion, 10-100 parts of water, 1-5 parts of bentonite, 50-100 parts of barium sulfate, 50-150 parts of non-metallic mineral and 200-600 parts of wear-resistant aggregate; the second composition comprises, by weight, the following raw materials: 0.1-3 parts of a cross-linking agent, 4-55 parts of a curing agent,0.4-5 parts of an emulsifier and 1-20 parts of water; each composition is independently packaged. The coating components does not contain an organic solvent, is not inflammable or explosive, and is safe to transport and store; the preparation process is simple and environment-friendly, the influence on workers and environment is small, the materials are common and easy to obtain, the cost is low,and the shelf life is long; the coating can be applied indoors and outdoors and has very wide application space.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a pavement coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for road landscape and comfort are getting higher and higher, and various colored road surfaces have also emerged as the times require. At present, the techniques for realizing colored pavement include: colored asphalt, colored permeable concrete pavement, colored anti-slip thin layer, and colored painted pavement. Among them, the color sprayed pavement has gradually become the mainstream of the market because of its convenient construction, little damage to the original pavement, beautiful and comfortable, and low cost. At present, the materials that can be used for floor coating mainly include epoxy resin, acrylic and polyurethane. Among them, the mechanical strength and adhesion of acrylic and polyurethane coatings are n...
