Description
Technical Field
The invention relates to the technical field of sealant adhesion in the building industry, in particular to an environment-friendly luminous weather-resistant adhesive and a manufacturing process thereof.
Background
The luminous glue is mainly used for sealing the inner sides of doors and windows, sealing indoor doors, sealing skirting lines, sealing bathrooms, decorating and finishing movie and television walls and the like. The adhesive has the advantages of convenient adhesion, light absorption, repeated luminescence, attractive appearance and the like, is particularly popular with customers when being applied to interior decoration, and is accepted by the market and users. However, most of the common noctilucent glues currently available in the market have phenomena such as excessive shrinkage ratio, glue fracture and the like.
The phenomenon of overlarge shrinkage ratio is caused by a simple production process of combining noctilucent powder into colloid because the noctilucent powder is simply added into the colloid. Too large shrinkage ratio can stretch the wall and other profiles attached by the colloid, and the wall can crack on a fragile wall; under the condition that the section bar is firm, the colloid extends for a long time, so that the colloid has low fullness, and the phenomena of cracking and the like are easy to occur. And if the nano calcium powder is added, the noctilucent effect is extremely influenced, so that some manufacturers display the defects of other properties when pursuing the noctilucent effect.
Regarding the phenomenon of colloid fracture, the colloid fracture can be caused after the ordinary glue and the luminous powder are simply combined, and the reason is two points. Firstly, simply combine several kinds of mucilage, ordinary producer's technical staff can all accomplish, and the simplest is just mixing. Relatively, each glue is a separate system, and has no problem when used independently, if the glue is used after being mixed, the original system is disturbed, and a perfect system is reestablished, so that a lot of manpower and material resources are consumed to complete the glue by one step through experiments, and the problems of glue fracture, glue oil production, mixture separation and the like can occur after simple mixing; secondly, because each adhesive cement is provided with a production process of the own system due to different production processes, products are definitely different due to different processes, and therefore the problem of adhesive fracture is easily caused.
Therefore, the common noctilucent glue on the market at present can reduce cracking but cause poor or no noctilucent effect due to the addition of nano calcium powder, and the glue fracture phenomenon can occur after a long time, so that the appearance is very influenced and the practicability is very improved. In addition, the emission of volatile organic compounds of the existing major part of the luminescent glue is large, pungent odor is generated, and the important indication and requirement of the existing country on energy conservation and environmental protection cannot be met.

In the invention, the hydrophilic nano fumed silica is selected as the filler, is a product with the best light transmittance in the optical light transmittance, can show the maximum luminous transmittance and can play a role of the filler, so that the shrinkage ratio of the colloid is reduced to the minimum, the stress body is protected, the phenomena of stress body fracture and the like caused by overlarge shrinkage ratio are prevented, and the optimal addition ratio is obtained through multiple experiments.
The manufacturing process is provided with the step of manufacturing the premixed liquid, and the noctilucent powder and the plasticizer are well mixed and mixed together through stirring of the vacuum high-speed dispersion machine, so that the three problems of colloid fracture, mucilage oil production and mixture separation are solved. And if the step of preparing the premix liquid is not arranged, any powder cannot be well mixed with the plasticizer, so that one or all of the three problems of colloid fracture, mucilage oil production and mixture separation can be caused. In addition, in the manufacturing process, the order of adding the materials is correctly added, the production is strictly carried out according to the process requirements, and the phenomena of colloid fracture and the like caused by the reaction among the materials due to disordered material orders are prevented.
The special pure acrylic resin emulsion has the characteristics of strong adhesion, long extensibility and strong ageing resistance. The required fineness of the noctilucent powder is lower, and the noctilucent powder can be fully and more uniformly filled in each part of the colloid, so that the colloid can absorb and release light more strongly, the duration is longer, and the number of times of recycling is more. The weather-resistant auxiliary agent is mainly prepared by mixing and matching an anti-aging agent, an ultraviolet absorber and an antibacterial bacteriostatic agent, and plays an important role in the weather resistance of the colloid. The plasticizer adopts dioctyl phthalate, so that the requirement of environmental protection can be met, and the phenomena of external oil seepage and the like do not occur in cohesive plasticization. In the third step of the manufacturing process, before the bactericide and the defoaming agent are added, the consistency of the liquid in the vacuum planetary mixer needs to be observed, and after the consistency meets the requirement, the bactericide and the defoaming agent are added, wherein the consistency can be adjusted by adding the thickening agent.
The environment-friendly luminous weather-resistant adhesive improves the light resistance and aging resistance of the product by adding the weather-resistant auxiliary agent comprehensively, and changes the habit that the weather-resistant auxiliary agent is not adopted indoors in the past, thereby preventing the long-term harm to the residents caused by the powder removal of the adhesive. And has stronger protection to the indoor resident. For example: the old man, children have stronger night light lines to each article of door frame, bathroom in the dark under the night light reflection of environmental protection night light glue, relatively easy discernment, the emergence of the accident such as falling down of significantly reducing simultaneously. The light-emitting diode is also popular in the fields of video walls and the like due to the characteristics of repeated light emission, simple construction, energy conservation, zero emission and the like.
