Abstract
The invention belongs to the technical field of adhesives, and particularly relates to a preparation method of a waterproof flame-retardant adhesive for an elastic coiled material.
Description
Technical Field
The invention belongs to the technical field of adhesives, and particularly relates to a preparation method of a waterproof flame-retardant adhesive for an elastic coiled material.
Background
The success of waterproofing of polymer-modified waterproofing membranes depends not only on their own quality, but also is closely related to the adhesive sealing of the membrane to the roof. The traditional construction method of the modified waterproof coiled material is hot melting construction, the surface of the coiled material is melted by heating and then is bonded with the roof, the construction method is large in labor amount and pollutes the environment, and the bonding and sealing of the coiled material and the roof or the lap joint of the coiled material are not tight due to slight improper construction, so that the roof leakage is caused. The self-adhesive modified adhesive is an important raw material for producing modified waterproof coiled materials. The high-strength self-healing concrete has the advantages of high strength, high elongation, good adhesion, excellent low-temperature flexibility, self-healing property, convenience and quickness in construction and the like. The adhesive is not only an adhesive layer between the cladding material and the roof, can keep the adhesive sealing performance for a long time, but also is a stress buffering and absorbing layer between the coiled material and the roof. When the roof cracks due to stress, the bonding layer has plasticity and considerable ductility, can buffer or absorb the roof stress through self deformation, and reduces the influence of the roof deformation on the cladding material, thereby prolonging the service life of the coiled material and solving the problem of difficult construction of the traditional coiled material. Although asphalt has some viscosity and thermoplasticity,
but the thermal stability is poor, the cold brittleness and the hot flowing are poor, and the performance is not ideal when the material is used as a binding material. In the prior art, rubber is selected as a main modification component, so that the heat resistance and low-temperature flexibility are obviously improved, and the rubber component is similar to a polymer modification material in a novel asphalt coiled material, so that the cohesiveness is improved to a certain extent. However, rubber-modified asphalt represented by SBS is mainly processed under high temperature conditions by mechanical shearing or the like, and once the temperature is lowered, the asphalt and the modifier may be poor in compatibility and cause phase separation, which is disadvantageous in quality stability of the modified asphalt. The technical personnel in the field need to develop a preparation method of waterproof flame-retardant adhesive for elastic coiled materials so as to meet higher use requirements and market demands.

Further, the stabilizer is one or more of dimethyl tin, dioctyl tin and tetraphenyl tin.
Further, the mass ratio of the matrix asphalt, the mixed resin, the cross-linking agent, the stabilizing agent, the liquid nitrile rubber and the emulsifying agent is 100: 11-20: 0.1-0.2: 30-60: 6-9.
The mass part ratio of the vinyl ester resin to the thermoplastic polyurethane is 3-6: 3-5.
Further, the interfacial agent is methoxy silane or ethoxy silane; the antifreezing agent is poly propylene glycol adipate; the anti-aging agent is styrenated phenol, and the cross-linking agent is tetramethylenediamine.

The vinyl ester resin and the asphalt are subjected to chemical reaction to a certain extent, partial aromatic components and saturated components are consumed, the compatibility between the vinyl ester resin and the asphalt is better, and the physical mixture formed by mutual penetration and entanglement is the composition and composition of IPN, so that the performance is more excellent than that of a common blend. The reason for this is that one component and the other component are randomly penetrated, so that a synergistic effect is generated between the two components in the IPN system, and the ductility and the wax content of the polyurethane asphalt have important influence on the bonding performance to ensure the bonding performance of the adhesive.
