Description
Technical Field
The invention relates to the technical field of pressure-sensitive adhesives, in particular to a non-vulcanized butyl pressure-sensitive adhesive, a preparation method and application thereof, and a waterproof roll.
Background
The waterproof coiled material is mainly used for building walls, roofs, tunnels, highways and refuse landfills, can be curled into a roll-shaped flexible building material product which can resist external rainwater and underground water leakage, is a waterproof first barrier of the whole project, plays a vital role in the whole project, and a key substance in the waterproof coiled material is hot melt adhesive.
The whole construction process of laying the waterproof roll has a lot of attention points, wherein the most important is base layer treatment, because the common pressure-sensitive adhesive can only be used under the dry condition, if the waterproof roll is used in water or a humid environment, the bonding strength of the hot melt adhesive and a building or other objects is greatly reduced, the waterproof effect of the waterproof roll is poor, and even the waterproof effect can not be achieved, therefore, the base layer treatment is mainly used for removing the open water on the surface of the building or other objects, and it can be understood that if the open water exists on the surface of the building or other objects, the open water cannot be removed by the hot melt adhesive, and the bubbling phenomenon can occur on the surface of the laid waterproof roll; and the viscosity of the hot melt adhesive is reduced after the hot melt adhesive meets the open water, so that the bonding strength between the waterproof coiled material and a building or other objects is reduced, and the waterproof coiled material is easy to peel off from the building.
In conclusion, the hot melt adhesive of the waterproof roll material limits the application range of the waterproof roll material and reduces the applicability of the waterproof roll material. And the hot melt adhesive in the waterproof roll material improves the requirement on weather in the waterproof roll material construction process, and reduces the construction efficiency of the waterproof roll material.

The present application provides a non-vulcanized butyl pressure sensitive adhesive. The non-vulcanized butyl pressure-sensitive adhesive comprises the following components: ethylene propylene rubber, polyisobutylene, butyl rubber, tackifying resin, carboxymethyl cellulose, a filler and an auxiliary agent.
In the non-vulcanized butyl pressure-sensitive adhesive, the butyl rubber is utilized to ensure stronger bonding strength in water, and the polyisobutylene, the ethylene propylene rubber and the tackifying resin are utilized to be matched with the butyl rubber, so that the infiltration capacity and the bonding strength of the non-vulcanized butyl pressure-sensitive adhesive are effectively improved, so that the non-vulcanized butyl pressure-sensitive adhesive has enough initial adhesion force and can be used for realizing the adhesion of buildings or other objects in water, and uses sodium carboxymethylcellulose, filler and auxiliary agent to match with butyl rubber, polyisobutylene, ethylene propylene rubber and tackifying resin, so as to remove moisture existing between the adhesive and the surface of an object, and the aging resistance of the non-vulcanized butyl pressure-sensitive adhesive is improved, the bonding strength of the non-vulcanized butyl pressure-sensitive adhesive is further improved, and the bonding stability of the non-vulcanized butyl pressure-sensitive adhesive is further improved.
For a better understanding of the non-vulcanized butyl pressure sensitive adhesive of the present application, which is further explained below, one embodiment of the non-vulcanized butyl pressure sensitive adhesive comprises the following components: ethylene propylene rubber, polyisobutylene, butyl rubber, tackifying resin, carboxymethyl cellulose, a filler and an auxiliary agent.
The non-vulcanized butyl pressure-sensitive adhesive is characterized in that waterproof construction needs to be carried out on an object with a surface containing water or waterproof construction needs to be carried out on a building or other objects in water, the adhesive still needs to have good bonding strength in water, in the non-vulcanized butyl pressure-sensitive adhesive, the butyl rubber is utilized to ensure that the adhesive has strong bonding strength in water, but only the butyl rubber is not enough to be used for gluing the building or other objects in water, so that polyisobutylene, ethylene propylene rubber and tackifying resin are also utilized to be matched with the butyl rubber, the infiltration capacity and the bonding strength of the non-vulcanized butyl pressure-sensitive adhesive are effectively improved, and the non-vulcanized butyl pressure-sensitive adhesive has enough initial adhesion, namely, the non-vulcanized butyl pressure-sensitive adhesive is enough to glue the building or other objects in water; after the adhesion between the adhesive and the surface of an object is realized, because moisture must exist between the adhesive and the surface of the object, the adhesive coated on the surface of the object has a bubbling phenomenon, the moisture is easy to flow between the adhesive and the surface of the object, the adhesion stability is reduced, and the adhesive is easy to fall off from the surface of the object, therefore, in the non-vulcanized butyl pressure-sensitive adhesive, sodium carboxymethyl cellulose, a filler and an auxiliary agent are utilized to be matched with butyl rubber, polyisobutylene, ethylene propylene rubber and tackifying resin for use, the sodium carboxymethyl cellulose and the filler are used in the non-vulcanized butyl pressure-sensitive adhesive, so that the non-vulcanized butyl pressure-sensitive adhesive has the capacity of absorbing moisture and combining with the moisture, the filler enables the moisture existing between the adhesive and the surface of the object to be absorbed into the adhesive, and the sodium carboxymethyl cellulose enables the moisture absorbed into the adhesive to be converted into the combined water of the non-, and the moisture existing between the adhesive and the surface of an object is removed, the auxiliary agent has good oxidation resistance and coupling effect on the non-vulcanized butyl pressure-sensitive adhesive, the aging resistance of the non-vulcanized butyl pressure-sensitive adhesive is effectively improved, the bonding strength of the non-vulcanized butyl pressure-sensitive adhesive is further improved, and the bonding stability of the non-vulcanized butyl pressure-sensitive adhesive is further improved.
It should be further explained that after the non-vulcanized butyl pressure-sensitive adhesive realizes the adhesion of buildings or other objects in water, moisture still exists between the adhesive and the object surface, the moisture forms a water film between the adhesive and the object surface, due to the existence of the surface tension of the water film, and the filler in the non-vulcanized butyl pressure-sensitive adhesive has a larger absorption force on the water film, so that the water film between the adhesive and the object surface is absorbed, in the absorption process, the water film absorbed by the filler can be gradually combined with the sodium carboxymethyl cellulose to form the combined water in the non-vulcanized butyl pressure-sensitive adhesive, and further the moisture is removed, and after the carboxymethyl cellulose absorbs the water film, the viscous colloid is formed by the carboxymethyl cellulose, so that the adhesive strength of the non-vulcanized butyl pressure-sensitive adhesive is improved, and the volume of the absorbed carboxymethyl cellulose water film is close to the total volume of the carboxymethyl cellulose and the water film, the space occupied by the original water bead is filled and adhered, a tight bond is formed. It can be understood that if the non-vulcanized butyl pressure-sensitive adhesive does not contain sodium carboxymethyl cellulose, excessive water film absorption by the filler can cause the bonding force between the filler and other substances of the non-vulcanized butyl pressure-sensitive adhesive coating to be reduced, so that the non-vulcanized butyl pressure-sensitive adhesive coating formed on the surface of an object forms column marks, and the non-vulcanized butyl pressure-sensitive adhesive coating formed on the surface of the object is damaged; if the non-vulcanized butyl pressure-sensitive adhesive does not contain the filler, the non-vulcanized butyl pressure-sensitive adhesive has poor absorption capacity on the water film, and is difficult to absorb the water film and further difficult to remove the water film.
