preparation example Construction

[0040] 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:

[0041] (1) Preparation of component A: Mix fumed silica, organic boron clay, inorganic iron oxide pigment, talc powder, silica fume powder and quartz sand to obtain an inorganic mixture, and then add standard bisphenol Mix A epoxy resin evenly, then add epoxy-based toughener, AGE reactive diluent, defoamer, leveling agent and wetting agent and mix evenly to obtain component A;

[0042] (2) Preparation of component B: Mix the modified alicyclic amine curing agent, silane coupling agent and polyamide curing agent evenly to obtain component B;

[0043] (3) Mix components A and B evenly to obtain a two-component road surface anti-skid coating.

[0044] In actual use, use spraying equipment to spray the two-component road surface anti-skid coating prepared above onto the construction road surface, use a roller...

Embodiment

[0046] An epoxy-modified two-component road surface anti-skid coating, 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.

[0047] Among them, the toughening agent containing epoxy group was purchased from Juncai Material Technology Co., Ltd., the brand is BI7770. The silicone defoamer was purchased from Hebei Zhengqian Chemical Products Co., Ltd., the polyether defoamer was purchased from Hebei Leyi Energy Saving Technology Co., Ltd., and the amide defoamer was purchased from Shanghai Guangbai New Material Co., Ltd.

Abstract

The invention provides a reduction-oxygen-modified two-component pavement antiskid coating. The coating comprises a component A and a component B, an epoxy group-containing toughening agent is used inthe component A and is matched with the modified alicyclic amine curing agent, the silane coupling agent and the polyamide curing agent in the component B. Therefore, the pavement antiskid coating has stronger bonding force and excellent toughness, and can better adapt to the ductility of an asphalt pavement. In a preferred scheme of the invention, quartz sand is added into the component A, so that tiny air holes can be formed after the coating is cured, and hollowing and delaminating caused by pressure formed by water vapor below the coating are prevented. 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 pavement coatings, in particular to an epoxy-modified two-component pavement 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. Contents of the invent...
