Abstract
The invention discloses an adhesive film for paving a polymer industrial floor, which comprises a base material, wherein the whole body of the base material is coated with a resin adhesive; the base material comprises fiber cloth; the resin adhesive comprises the following components in parts by weight: epoxy resin, flexible resin, diluent, tackifier, water absorbent, ketone imine curing agent and filler. The special resin adhesive prepared by taking the epoxy resin, the tough resin and the ketimine curing agent as raw materials is matched with the specific base material, and the prepared adhesive film solves the problem of labor cost caused by on-site adhesive preparation and scraping in the paving of the high-molecular industrial floor.
Description
Technical Field
The invention relates to the technical field of industrial floor paving application, in particular to an adhesive film for paving a polymer industrial floor and a preparation method thereof.
Background
The industrial production environment is more and more intelligent, the requirements on the renovation and the reconstruction of factory floors and the speed and the progress of newly-built factory buildings are very high, the construction of ground materials needs to be completed in a very short time, and particularly in the current new energy, hydrogen energy, semiconductor and chip industries, each new factory project is competing with the time.
At present, the floor material gradually enters the factory production from the field solidification and is prepared into a form of paving on the spot after being coiled; however, in the field paving construction process, the coating of the high molecular industrial floor adhesive is still needed to complete the paving of the coiled material. Most of the currently used polymer industrial floor adhesives are double components, the adhesives belong to paste substances, and the double components needing to be prepared in the construction process are strictly and uniformly stirred according to the proportion; in addition, a large amount of labor is needed for scraping glue, and manual operation has the characteristics of low speed and low efficiency; and the scraping time is critical, and the scraping of the whole area must be completed within half an hour, otherwise partial adhesive failure may result.
Therefore, it is very important to develop an adhesive film for paving polymer industrial floors.
Disclosure of Invention
The invention provides a high polymer industrial floor paving adhesive film and a preparation method thereof, the adhesive film is suitable for paving a high polymer industrial floor, can replace the existing double-component adhesive, and has the characteristics of convenient transportation, high bonding strength, good toughness, moderate hardness, convenient construction and high construction speed, and the storage condition is not harsh and the storage time is long.
The specific technical scheme is as follows:
the invention relates to an adhesive film for paving a polymer industrial floor, which comprises a base material, wherein the whole body of the base material is coated with a resin adhesive; the substrate comprises a fiber cloth;
the resin adhesive comprises the following components in parts by weight:
the invention selects the ketimine curing agent to be combined with the epoxy resin and the tough resin, so that the raw material components in the resin adhesive have a delayed reaction phenomenon, namely: the resin adhesive is prepared in a dry environment, so that the ketimine curing agent in the components can not react with epoxy resin and tough resin, and a stable adhesive film without obvious viscosity is obtained; when the polymer industrial floor is paved, the resin adhesive component ketone imine curing agent on the outer surface of the adhesive film reacts with moisture in the ground and air to be decomposed, so that the resin adhesive film is subjected to curing reaction with epoxy resin and tough resin to form the adhesive film with strong viscosity, and the paving requirement of the industrial floor is met.
The ketimine curing agent is a condensation polymer prepared by the reaction of ketones and poly-primary amine, the reaction is reversible, once the ketimine curing agent meets water and moisture, polyamine and corresponding ketones are dissociated, after the reverse reaction, the decomposed polyamine is an epoxy resin curing agent, and can rapidly react with an epoxy group to form a cured product after crosslinking and curing, so that the bonding effect is achieved. The epoxy resin has the advantages of high activity, high reaction speed, high epoxy value, large curing agent amount required by reaction, excellent toughness of the tough resin, low epoxy value and small amount of required curing agent, and the combination of the epoxy resin and the tough resin has high solid content of the resin and small using amount of the curing agent, thereby being beneficial to prolonging the storage time of the adhesive film.
The adhesive film obtained by the principle improves the construction convenience and does not need manual scraping. Meanwhile, the fiber cloth with a certain fixed shape is used as a base material, so that the bonding area and the bonding strength of the foundation ground and the polymer industrial floor are greatly improved, bubbles generated during bonding can be well eliminated by the fiber cloth, the bonding integral performance is improved, and earthworm grains generated by the polymer industrial floor due to tiny and tiny cracks on the ground are eliminated.
The fiber cloth is used as a base material, integrity and stability of the whole adhesive film can be improved, a reinforcing effect is achieved, the bonding area and bonding strength of the basic ground and the polymer industrial floor are greatly improved, bubbles generated during bonding can be well eliminated, the bonding integral performance is improved, and earthworm grains of the polymer industrial floor caused by small and fine cracks on the ground are eliminated. Further, the fiber cloth is at least one of glass fiber woven cloth, carbon fiber woven cloth and polyester woven cloth; the thickness of the fiber cloth is 0.2-1.5 mm. The fiber cloth is too thin, the glue content is low, hollowing is easy to generate when the industrial floor is paved, and the bonding strength is reduced; the fiber cloth is thick, the hardness is easy to increase, the thickness of the glue layer is too thick, and the unevenness phenomenon is easy to occur when the industrial floor is paved.
In order to further improve the adhesive content, the bonding strength and the bonding contact area of the base material, the base material further comprises non-woven fabrics attached to the upper surface and/or the lower surface of the fiber cloth; the non-woven fabric is at least one of carbon fiber felt, PP non-woven fabric and PET non-woven fabric. The use of non-woven fabrics can increase whole bonding strength, increases the bonding area, improves the industrial floor flatness of mating formation.

The too low gram weight and the too low thickness of the non-woven fabrics lead to easy cracking and wrinkling, and can not achieve the function of increasing the strength of the adhesive, and the too high gram weight and the too high thickness lead to too large proportion of the non-woven fabrics in the rubber sheet composition, and serious deformation during the paving use, thus leading to uneven paved industrial floors. The tensile elongation of the elastic thread and the non-woven fabric is more than or equal to 100 percent, so that a certain amount of deformable allowance can be ensured in the use process of the film, and the film is suitable for the anisotropic size of the bonded ground.

Furthermore, the tough resin is a liquid polymer, a branched chain polymer containing ether and polyurethane groups, and a hydroxyl-terminated modified liquid nitrile rubber prepolymer, and the epoxy equivalent is 800-2500 g/eq.
