Problems solved by technology

[0008] However, the polysiloxane coupling agent, polynaphthalene sulfonic acid sodium salt or In the reaction mechanism of silane coupling agent, titanate coupling agent and aluminate coupling agent, only the chemical crosslinking reaction and physical mortise and tenon synergistic bonding with uncured cement were proposed, but the coupling was not realized. The coupling agent can have a strong chemical bond with the bitumen at the other end, so it is relatively blind and has no sense of direction when choosing a coupling agent. Therefore, when manufacturing waterproof membranes or reactive bonding joint sealants The expected effect is often not achieved, and it is only better than ordinary waterproof membranes or sealants, and the aging and weather resistance of asphalt have not been significantly improved.

Abstract

The invention discloses a beta-(3,4-epoxy group cyclohexyl)trichlorosilane asphalt cement waterproof bridging agent, a waterproof product and applications thereof. Epoxy group on one end of the structure of the bridging agent can be connected with the carboxyl and hydroxyl in asphalt to achieve good chemical affinity. The other end of silane can be combined with hydrated calcium silicate or calcium aluminate to form chemical bonds, wherein the hydrated calcium silicate and calcium aluminate are generated during the hydration process of cement. The bridging agent can be subjected to chemical crosslinking reactions with concrete, the asphalt and cement are tightly bound together, chemical bond effect exists in related parts, just like a bridge is built, after curing, an irreversible binding force is formed, the bridging agent can be made into waterproof coiled materials, waterproof paint, waterproof paste, and waterproof plugging agent, during the process of cement solidification, the bridging agent can creep and penetrate into the pores of cement gel and concrete capillaries, and thus the bridging agent and cement are tightly, firmly, and irreversibly bound together.

Description

technical field [0001] The invention relates to an additive for building waterproof materials, especially a bridging agent capable of performing chemical crosslinking reaction with asphalt and cement at the same time to form a chemical bond with better chemical affinity, and to make it play an irreversible bonding role after curing and Its waterproofing products and applications. Background technique [0002] Common building waterproof materials are mainly cement and asphalt. Asphalt is mainly used for plugging the joints of concrete or the gaps around the wall, or spread on the roof to bond thin bricks to prevent leakage, and can also be made into waterproof membranes. Seepage-proof and rain-proof occasions. Yet current asphalt is difficult to carry out better plugging and leak prevention, and its reason is that the bonding of asphalt and solidified cement (concrete) is very not lasting, mainly is that asphalt is the residue after oil extraction gasoline, kerosene etc., M...
