Description
Technical Field
The invention belongs to the technical field of adhesive auxiliaries, and particularly relates to a rock plate pretreating agent.
Background
The rock plate is a stone material obtained by pressing and high-temperature firing natural raw materials, has strong plasticity, can form rich and beautiful textures, and has excellent scratch resistance and anti-permeation performance, so the rock plate can be widely applied to indoor and outdoor building and decoration materials, such as background walls, stairs, windowsills, cabinets and the like. At present, the use of rock plate glue for bonding is the most common way to secure rock plates. In the process of practice and research, a large number of cases of adhesive failure are analyzed, and the fact that interface failure rather than cohesive failure generally occurs between the rock plate glue and the rock plate is found, and the adhesive capacity of the rock plate glue on the surface of the rock plate is a main factor limiting the adhesive strength of the rock plate glue. Therefore, how to improve the adhesion capability of the rock plate glue on the surface of the rock plate is a primary technical problem.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a new scheme, which changes the traditional use method of the rock plate adhesive, and the rock plate adhesive is not directly coated on the surface of the rock plate, but is pretreated by using a pretreatment agent firstly and then coated with the rock plate adhesive. The invention relates to a rock plate pretreating agent which comprises the following components:
a rock plate pretreating agent comprises the following components in parts by weight:
100 portions of ethanol
80-120 parts of petroleum ether
2-3 parts of water-based rosin tackifying emulsion
15-25 parts of polyethylene glycol diacrylate
8-15 parts of 1, 6-hexanediol diacrylate
8-12 parts of silicon dioxide powder subjected to silane coupling treatment
5-10 parts of carbon fiber powder
0.2 to 0.3 portion of propylene glycol monobutyl ether
3-5 parts of a photoinitiator.
Wherein, the polyethylene glycol diacrylate is preferably PEGDA-200; the particle size of the carbon fiber powder is preferably 300-1000 meshes; the photoinitiator is preferably the photoinitiator TPO (1108).
The preparation method of the silicon dioxide powder subjected to silane coupling treatment comprises the following steps: preparing an ethanol solution of KH560 with the mass fraction of 2.0-2.5%, then dripping hydrochloric acid to adjust the pH value to 3.5-4.5, stirring for 20-40min, adding silicon dioxide powder, heating to 70-76 ℃, continuing stirring for 2-3h, filtering out the silicon dioxide powder, washing off residual liquid on the surface by using ethanol, and drying to obtain silicon dioxide powder subjected to silane coupling treatment. The particle size of the silicon dioxide powder used is preferably 240-800 mesh; the drying temperature is preferably 105-110 ℃.
The application method of the rock plate pretreatment agent provided by the invention comprises the following steps: the components are mixed according to a ratio to form a uniformly dispersed mixture, then the uniformly dispersed mixture is coated on the surface of a dry and clean rock plate, then an ultraviolet lamp is used for irradiating for a period of time, and then rock plate glue is coated.
When the pretreatment agent is used, the rock plate pretreatment agent is preferably sprayed on the surface of the rock plate by a spraying method, and the spraying amount is preferably 320-450g/m2. The technological parameters irradiated by the ultraviolet lamp have great influence on the bonding performance of the subsequent rock plate glue, and after a period of irradiation, the pretreatment agent sprayed on the surface of the rock plate is in a near-dry state, and then the rock plate glue is coated. For example, the power of the ultraviolet lamp tube is 1000W, the vertical distance between the ultraviolet lamp tube and the rock plate is 20cm, and the rock plate is placed in a windless open environment, and the ambient temperature is 25 +/-3 ℃. Taking the above conditions as an example, the irradiation time is usually 350-470s, so that the pretreatment agent just reaches a viscous state near dry. If the irradiation time is too short, the content of the solvent in the pretreating agent is too high, the pretreating agent layer is in a flowable state, and the action time of the initiator is also too short, so that the bonding property after the subsequent coating of the rock plate adhesive is far lower than the optimal state; if the irradiation time is too long, the solvent in the pretreating agent is completely volatilized, the pretreating agent is in a completely dry state, and pretreatment is carried outThe silicon dioxide powder and the carbon fiber powder in the physical agent layer are partially aggregated and separated, and the bonding performance after the subsequent coating of the rock plate adhesive is also reduced. It should be noted that the above conditions of the ultraviolet light treatment are only for explaining the light irradiation and the volatilization degree of the solvent, and the ultraviolet light treatment is not limited to be performed by the same method. The ultraviolet light treatment is carried out under other conditions, and corresponding parameters can be reasonably set according to the light and the volatilization degree of the solvent under the conditions.
Has the advantages that: compared with the prior art, the rock plate pretreating agent provided by the invention is used for pretreating the surface of the rock plate before coating the rock plate adhesive, so that the adhesive property of the rock plate adhesive on the surface of the rock plate is improved, and the finally expressed adhesive property of the rock plate adhesive is improved.
