Problems solved by technology

Cement-based joint fillers are prone to uneven dispersion during the mixing process. When the powder is agglomerated with the mortar for construction, problems such as cracking will occur after drying, and its curing mechanism is mainly cement hydration, accompanied by cement water. As the chemical process proceeds, the material begins to thicken and eventually cannot be constructed
Epoxy caulking materials are expensive, although their construction effect is excellent, but they are not suitable for large-scale use in outdoor environments
At the same time, epoxy is cured by two-component reaction. When the ratio is wrong, the curing speed will be slow, no curing or bursting will occur.

Abstract

The invention relates to a colored pasty joint mixture for pervious concrete and a preparation process of the colored pasty joint mixture. According to the invention, polymer resin is selected as a cementing material, the phenomena of saltpetering and mildewing cannot occur in a later period, so the attractiveness of the joint mixture is guaranteed; a silane coupling agent is selected in the joint mixture, the dispersity and the adhesive force of raw materials are effectively improved; meanwhile, compatibility between filler and resin is better, and therefore, the joint mixture is better in elasticity and better in durability, and the impermeability of the joint mixture is improved; and the filler is at least one selected from ground calcium carbonate, titanium dioxide, quartz powder and talcum powder, so the ductility and the wear resistance of the joint mixture are also effectively improved. The joint mixture with high elasticity, high ductility, wear resistance, skid resistance, acid and alkali resistance and good impermeability is obtained through regular and constant-speed stirring and mixing by utilizing stirring equipment, and the joint mixture can be used in an outdoor environment and can be further used on pervious concrete.

Description

technical field [0001] The invention relates to the technical field of caulking agents, in particular to a colored paste-like caulking agent for permeable concrete and a preparation process thereof. Background technique [0002] At present, the joint sealants on the market are mainly divided into the following two categories: the first category is the most widely sold cement-based joint sealant, which has the characteristics of low price and convenient construction, but the cement-based joint sealant requires on-site Add water or emulsion and stir before proceeding with subsequent material construction. The other type is epoxy caulking agent, and epoxy caulking agent is expensive, the construction period is long, and the requirements for construction personnel are high. At the same time, the curing method of epoxy caulking agent is to react with the curing agent together. When the two are mixed unevenly, problems such as non-curing and excessive curing speed will occur. ...
