preparation example Construction

[0037] The embodiment of the present invention also relates to the preparation method of this two-component road surface anti-skid coating, comprising the following steps:

[0038] (1) Preparation of component A: Mix fumed silica, organoboronite, inorganic iron oxide pigments, talc powder, silica fume powder and colored ceramic particles to obtain an inorganic mixture, and then add water-based ring to the inorganic mixture Mix oxygen resin and water-based acrylic resin evenly, then add water-based anti-settling agent, water-based defoamer, water-based dispersant and wetting agent and mix evenly to obtain component A;

[0039] (2) Preparation of component B: Mix the water-based epoxy curing agent and deionized water evenly to obtain component B;

[0040] (3) Mix components A and B evenly to obtain a two-component road surface anti-skid coating.

[0041] In actual use, use spraying equipment to spray the two-component road surface anti-skid coating prepared above onto the const...

Embodiment

[0043] A water-based epoxy acrylic modified two-component anti-skid coating for road surfaces, including A component and B component, the preparation method is the same as that described in the specific embodiment. The specific substances and contents of A and B components in Examples 1-6 and Comparative Examples are shown in Table 1.

[0044] Table 1

[0045]

[0046]

[0047] Mix component A and component B of the above examples and comparative examples uniformly according to the above proportions, let stand for 20 minutes until the air bubbles are eliminated, and then apply the coating evenly on the surface of the concrete sample, and form a coating with a thickness of 1 to 2 mm after curing. Floor. The mechanical properties of the coating were tested and the results are shown in Table 2.

Abstract

The invention provides a waterborne epoxy acrylic acid modified two-component pavement antiskid coating. The waterborne epoxy acrylic acid modified two-component pavement antiskid coating comprises acomponent A and a component B, wherein the component A contains water-borne epoxy resin and water-borne acrylic resin at the same time, so that the coating has better ductility, toughness and strengthafter being cured. In a preferred scheme of the invention, the colored ceramic particles with different particle sizes are added into the coating to serve as aggregate, so that the formed pavement has very good skid resistance and wear resistance. The invention further provides a preparation method of the pavement anti-skid coating. The method enables construction to be simpler and faster, the two components are mixed and stirred to be directly used, and auxiliary materials do not need to be additionally added. The use amount of materials is lower, repeated recoating can be achieved, secondary renovation is rapid and convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of epoxy resin coatings, in particular to a water-based epoxy acrylic modified two-component road surface anti-skid coating and a preparation method of the coating. Background technique [0002] Epoxy resin, as a kind of high-performance resin, is widely used. It has many advantages, including strong adhesion with various substrates, high hardness of the coating, good water resistance, chemical resistance and abrasion resistance, etc. It is often used in architectural coatings and road coatings. [0003] Epoxy resin pavement coatings have lower requirements on the base surface and have good adhesion to dry and wet base surfaces. However, due to rigidity and aging problems such as high brittleness, easy yellowing, and easy pulverization, existing epoxy resin coatings do not have good skid resistance and wear resistance, so they need to be modified. [0004] In view of this, the present invention is proposed...
