Problems solved by technology

[0007] However, the polysiloxane coupling agent, polynaphthalene sulfonic acid sodium salt or In the reaction mechanism of the silane coupling agent, only the chemical cross-linking reaction and the physical mortise and tenon synergistic bonding effect with the undried cement were proposed, but it was not realized that the coupling agent can have a strong chemical bond with the asphalt at the other end. Therefore, when choosing a coupling agent, it is relatively blind and has no sense of direction. Therefore, when manufacturing waterproof membranes or reaction-bonded joint sealants, the expected effect is often not achieved, and it is only better than ordinary waterproof membranes. The bonding of wood or sealant is better, and the aging and weather resistance of asphalt have not been significantly improved

Abstract

The present invention discloses an aluminate asphalt cement waterproof bridging agent, a waterproof product thereof and an application thereof. One end of a structural formula of the aluminate asphalt cement waterproof bridging agent can be connected with arboxyl or esteryl to form relatively good chemical affinity; the other end of the aluminate asphalt cement waterproof bridging agent can be bonded with hydrated calcium silicate or calcium aluminate generated in a cement hydration process to form a chemical bond; and the chemical bond and the concrete generate chemical cross-linking reaction just like forming a bridge for tightly connecting the asphalt and the cement into an integer; chemical bond actions exist in relevant parts, and make reversible bonding effects after curing. The waterproof bridging agent can be made into a waterproof roll or prepared into waterproof paint, waterproof cream or a waterproof plugging agent. In a cement curing process, the waterproof bridging agent can permeate into pores of cement gel and the concrete, thereby achieving tight and firm fastening and reversible bonding effects as flesh and blood.

Description

technical field [0001] The invention relates to an additive for building construction waterproof materials, especially a bridging agent capable of chemical cross-linking reaction with asphalt and cement at the same time, forming a chemical bond with better chemical affinity, and making it play an irreversible bonding role after curing And its waterproof products and applications. Background technique [0002] The common waterproof materials for building construction are mainly cement and asphalt. Asphalt is mainly used to plug leaks in the joints of concrete or the gaps around walls, or spread on the roof to bond thin bricks to prevent leakage. It can also be made into waterproof membranes and laid on Where anti-seepage and rain-proof are required. However, the current asphalt is difficult to better plug and prevent leaks. The reason is that the bonding between asphalt and cured cement (concrete) is not durable, mainly because asphalt is the residue after oil extraction of ...
