In order to solve the above technical problems, a first aspect of the present application provides an interfacial agent for interface treatment of a waterproof system, which is prepared from at least: organic emulsion, preservative, color paste and solvent;
the weight of the organic emulsion is 30-60wt% of the weight of the solvent.

In some preferred embodiments, the preparation raw materials of the pure acrylic emulsion comprise acrylic ester compounds and compounds 1; the molecular formula of the compound 1 is CH 2 =crcooh, wherein R is selected from H, CH 3 、CH 2 CH 3 One of them.
In some preferred embodiments, the compound 1 has the formula CH 2 =crcooh, wherein R is H.
In some preferred embodiments, the pure acrylic emulsion is a particle size nano-sized pure acrylic emulsion.
In some preferred embodiments, the particle size is 10-50nm.
In some preferred embodiments, the pure acrylic emulsion has a bromine number of 0.5 or less, preferably a bromine number of 0.3 or less.
The applicant has found out through a great number of creative experiments in the experimental process that the bromine number of the pure acrylic emulsion selectively added in the system greatly influences the bonding strength of the interfacial agent, and the applicant has found out through the experimental research that the bonding strength of the interfacial agent can be further improved when the bromine number is less than or equal to 0.5 and especially when the bromine number is less than or equal to 0.3, and the applicant speculates that the reason for the phenomenon is as follows: along with the change of the bromine number, the Mooney viscosity and the intrinsic viscosity of the pure benzene emulsion in the system are changed, the molecular weight is increased, the proper glass transition temperature is ensured when the pure benzene emulsion is compounded with the styrene-butadiene emulsion in the system, and the pure benzene emulsion has excellent bonding strength when being used at different temperatures.
In some preferred embodiments, the glass transition temperature of the neat acrylic emulsion is from 10 to 20 ℃.
In some preferred embodiments, the glass transition temperature of the neat acrylic emulsion is 15 ℃.

In some preferred embodiments, the weight ratio of the pure acrylic emulsion to the styrene-butadiene emulsion is 1:1.
in some preferred embodiments, the styrene-butadiene emulsion is a carboxylic acid styrene-butadiene copolymer emulsion.
A carboxylic acid styrene-butadiene copolymer emulsion, model 30Y160, was purchased from British.
The applicant has found out through a great deal of creative experiments in the experimental process that the permeation effect of the styrene-butadiene emulsion as an interfacial agent can be further improved through the synergistic effect of the styrene-butadiene emulsion and the pure acrylic emulsion, and the applicant speculates that the possible reasons are as follows: in the system, through the synergistic effect of the styrene-butadiene emulsion and the pure acrylic emulsion, the styrene-butadiene emulsion and the pure acrylic emulsion can be adsorbed on the surface of solid particles of the base material, and further complex occurs between the styrene-butadiene emulsion and metal plasma existing in the base material, so that the permeation effect of the styrene-butadiene emulsion and the pure acrylic emulsion on the surface of the base material is improved; meanwhile, because active groups exist in the styrene-butadiene emulsion and the pure acrylic emulsion, the styrene-butadiene emulsion and other compounds in the system can be further bonded; in particular, the weight ratio of the pure acrylic emulsion to the styrene-butadiene emulsion is 1: (0.5-1.5), in particular 1:1, as the pure acrylic emulsion is nano-scale emulsion, compact and ordered arrangement can be formed on the surface of the substrate, and the styrene-butadiene emulsion can be further doped in the pure benzene emulsion, so that the compactness and high adhesive force of the interfacial agent on the substrate layer are improved, meanwhile, migration of substances such as salt and the like is blocked, the permeation effect of the interfacial agent is enhanced, and the protection of the interfacial agent on the substrate layer is improved.
In some preferred embodiments, the preservative is present in an amount of 0.5 to 1.5wt% based on the weight of the organic emulsion.
The applicant has found that, through a great number of creative experiments, the service life and the use effect of the interfacial agent can be changed by adding the preservative into the organic emulsion in the experimental process, meanwhile, the prepared interfacial agent is ensured to have better storage stability, and especially when the weight of the preservative is 0.5-1.5wt% of the weight of the organic emulsion, the storage stability and the service life of the interfacial agent can be ensured, and meanwhile, the adhesive strength after soaking of the interfacial agent is further improved, and the applicant speculates that the reason for the phenomenon is as follows: when the preservative is 0.5-1.5wt% of the organic emulsion styrene-butadiene emulsion and the pure acrylic emulsion, the dispersion stability and the dispersion uniformity of the preservative in a system can be ensured, and when the interfacial agent is stored, the preservative can be combined with microorganisms such as bacteria in the interfacial agent in an omnibearing manner, so that the bacteria existing in the system can be effectively killed, and the service life of the preservative is prolonged; meanwhile, as substances such as bacteria and algae are easy to grow in water quality after soaking, the bacteria and algae substances can be killed in time, so that the problems that the adhesive force of the interfacial agent is reduced and the bonding strength of the soaked water is affected due to the growth of the bacteria and algae substances on a substrate layer are avoided; meanwhile, the applicant found that when the amount of the preservative added is more than 1.5wt% based on the weight of the organic emulsion, the preservative effect is easily reduced due to migration and escape of the organic groups contained therein from the constraint of the organic emulsion after being heated or immersed in water.
In some preferred embodiments, the preparation raw materials comprise, in parts by weight: 80-200 parts of organic emulsion, 0.5-1.5 parts of preservative, 0-0.5 part of color paste and 150-400 parts of solvent.
The second aspect of the present application provides a method for preparing an interfacial agent for interface treatment of a waterproof system, comprising the steps of:
s1: sequentially adding organic emulsion and preservative into a reaction kettle, controlling the reaction temperature to be 60-75 ℃, controlling the pH value to be 4-9, stirring and mixing;
s2: and (3) adding color paste in the step S1, adding solvent for dilution, controlling the solid content to be 8-20wt%, uniformly stirring, and discharging to obtain the color paste.
In some preferred embodiments, the solids content of step S2 is 10%.
In the experimental process, the applicant finds that the construction controllability of the interfacial agent in the use process can be improved by controlling the solid content of the prepared interfacial agent, and when the solid content of the interfacial agent is 10%, the reaction system can be better regulated to be in starvation, half starvation and overflow states in the reaction process, so that the stability of the reaction is improved, and further, the phenomena of foaming, pinholing and the like in the use process are avoided.
