Embodiment 1

[0048] Put 42kg of JF-3X fluorocarbon resin produced by Shanghai Dongfu Chemical into Wuxi Top brand stainless steel mixing tank, and then put the dispersing disc of Jiangyin Fine Chemical Co., Ltd. model FL22 high-speed dispersing machine in the mixing tank. Stir and disperse, then sequentially add 15kg of propylene glycol methyl ether acetate, 20kg of iron oxide red, and 22kg of high-grade clay into the mixing tank, and use a high-speed disperser to disperse and stir at a high speed for 30 minutes to obtain a mixture; then pass the prepared mixture through The horizontal sand mill of Kunshan Zhengdong Industrial Co., Ltd. grinds non-ferrous semi-finished products with a fineness of ≤20 microns. Then disperse the above-mentioned colored semi-finished products through a high-speed disperser, and add 0.15 kg of Deqian Chemical’s brand of Levelol835 acrylate leveling agent, 0.15 kg of Deqian Chemical’s brand of Defom5800F defoamer, and 0.7 kg of Deqian Chemical’s brand of Desettl...

Embodiment 2

[0052] Put 50kg of JF-3X fluorocarbon resin produced by Shanghai Dongfu Chemical into Wuxi Top brand stainless steel mixing tank, and then put the dispersing disc of Jiangyin Fine Chemical Co., Ltd. model FL22 high-speed dispersing machine into the mixing tank Stir and disperse, then add 12kg of trimethylbenzene, 25kg of iron oxide green, and 2kg of wollastonite powder into the mixing tank in sequence, and use a high-speed disperser to disperse and stir at high speed for 60 minutes to obtain a mixture; then pass the prepared mixture through Kunshan The horizontal sand mill of Zhengdong Industrial Co., Ltd. grinds colored semi-finished products with a fineness of ≤20 microns. Then the above-mentioned colored semi-finished product is dispersed through a high-speed disperser, and gradually added 0.2kg of Deqian Chemicals brand is the acrylate leveling agent of Levelol 835, 0.2kg of Deqian Chemicals’ brand is the defoamer of Defom 5800F, and 0.6kg of the BASF brand is 963S polyeth...

Abstract

The invention provides a permeable concrete pavement protection agent and a preparation method thereof. The permeable concrete pavement protection agent contains the following components (shown in the description), can improve the bonding properties of pavement aggregates, can improve the water permeable performance of a pavement and effectively prevent concrete whiskering, can make a pavement color more uniform, brighter and more durable, and meanwhile can also slow down the carbonization and aging speed of permeable pavement concrete and improve the usage durability of ecological pavements.

Description

technical field [0001] The invention relates to the technical field of additives in pavement mixtures, more specifically, to a permeable concrete pavement protective agent and a preparation method thereof. Background technique [0002] Permeable concrete is an eco-friendly concrete with continuous pores, good air and water permeability. The pavement of permeable concrete pavement can replenish groundwater, alleviate urban waterlogging, absorb sound and reduce noise, improve urban thermal environment, and has good environmental and social benefits. [0003] At present, the permeable concrete pavement is mainly composed of cement concrete inorganic concrete permeable pavement and asphalt permeable pavement, but this kind of permeable pavement surface layer has the characteristics of easy blotting, dull and single color, small particle size particles on the pavement surface layer, easy to run, and water permeable. There are many problems such as the inability to balance the pe...
