Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid glue, and particularly relates to a water-based glue liquid capable of being painted and played and a preparation method thereof. BACKGROUND

[0002] Liquid glue is a commonly used adhesive product in daily life. Its main features are: simple to obtain, convenient to prepare, good liquid flowability, and can be used in some simple bonding scenes in daily life, and is suitable for office workers, accountants, teachers and students and other related personnel.

[0003] Conventional liquid glue products are single, and the glue is colorless and transparent in appearance, only having a use function but no decoration function. Although the flash glue capable of playing a decoration role on the market has strong decoration, the adhesion is poor, has no or poor adhesion, and is difficult to clean. Since the existing liquid glue is difficult to simultaneously have high viscosity, high suspensibility and good flowability and continuity, the water-based glue liquid with good adhesion and capable of being painted and played cannot be obtained. SUMMARY

[0004] The first technical problem to be solved by the present application is to provide a water-based glue liquid capable of simultaneously having high viscosity, high suspensibility and good flowability and continuity, so as to realize the water-based glue liquid capable of being painted and played.

[0005] The second technical problem to be solved by the present application is to provide a preparation method of the water-based glue liquid.

[0006] The technical solution adopted by the present application to solve at least one of the above technical problems is as follows:

[0007] A water-based glue liquid capable of being painted and played, the raw materials used according to the weight percentage include the following components:

[0008] 7-13% polyvinyl alcohol,

[0009] 1-2% glycerol,

[0010] 1-3% water-based tackifying resin,

[0011] 0.5-1% suspending agent,

[0012] 0.1-0.5% thickening agent,

[0013] 0.05-0.2% pH regulator,

[0014] 0.1-1% dyeing agent,

[0015] 0.5-2% PET flash sheet,

[0016] 0.2-0.5% preservative,

[0017] and the balance is deionized water;

[0018] The pH of the obtained aqueous adhesive system is 5.5-6.5.

[0019] Preferably, the aqueous tackifying resin is at least one of aqueous acrylic resin, aqueous polyurethane, polyvinylpyrrolidone. These tackifying resins have good water solubility, little odor, no environmental pollution, convenient operation and processing, and obvious viscosity improvement effect.

[0020] Preferably, the suspending agent is at least one of carbomer 934, carbomer 940, carbomer 941. It has good swelling performance and good suspending effect on insoluble substances in the adhesive, which is beneficial to the mutual flow of the system adhesive.

[0021] Preferably, the thickening agent is at least one of sodium alginate, hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose. It has obvious effect on improving the viscosity of the system.

[0022] Preferably, the pH regulator is at least one of triethanolamine, sodium bicarbonate, AMP-95, sodium hydroxide.

[0023] Preferably, the preservative is at least one of MIT, MBIT, phenoxyethanol, nipagin ester.

[0024] In the present application, the molecular chain structure of the aqueous tackifying resin forms a three-dimensional network interpenetrating system with the nano-suspension agent, so that the aqueous adhesive forms a three-dimensional pseudoplastic fluid structure which can improve the carrying capacity of PET glitter sheet and establish a differentiated rheological gradient in the vertical direction. Under the condition that the pH regulator adjusts the pH of the aqueous adhesive system to 5.5-6.5, the carboxyl groups of the aqueous tackifying resin are fully dissociated, and the three-dimensional pseudoplastic fluid structure presents a dynamic crosslinking network with pH response.

[0025] A preparation method of an aqueous adhesive for drawing interesting pictures, comprising the following steps:

[0026] (1) preparing raw materials according to the formula of the aqueous adhesive of any one of claims 1-8;

[0027] Under room temperature conditions, deionized water and a suspending agent are sequentially added to a reaction kettle equipped with a stirring device, the stirring device is started and stirred at a speed of 250-300 rpm for 40-60 minutes to make the suspending agent fully and uniformly dispersed;

[0028] (2) maintaining the current stirring speed, adding a thickening agent to the reaction system and continuously stirring for 30-40 minutes to form a uniform premix;

[0029] (3) After adding polyvinyl alcohol (PVA) particles to the premixed system, keep the stirring rate for 10-20 minutes, then turn on the constant temperature heating system, accurately control the reaction temperature in the range of 90-95℃, and continue stirring for 2-3 hours until the polyvinyl alcohol is completely dissolved and uniformly dispersed;

[0030] (4) After the system is completely dissolved and uniform, adjust the stirring speed to 150-200 rpm, and set the reaction system temperature to 55-65℃, add glycerol, maintain the temperature under stirring for 20-40 minutes, adjust the stirring speed to 80-100 rpm, add the aqueous tackifying resin, and continue stirring for 30-60 minutes until all components are completely compatible;

[0031] (5) Add pH adjuster, continue stirring for 20-40 minutes until a homogeneous system is formed; then accurately control the pH value of the reaction system to the range of 5.5-6.5, thereby enhancing the stability of the system;

[0032] (6) Add preservative, reduce the stirring rate to 50 rpm, and perform vacuum degassing treatment at 55-65℃ constant temperature for 3-4 hours;

[0033] (7) According to the requirements, add colorants and PET flash sheets to the solution after degassing in step (6) for decoration, uniformly disperse, turn off the heating and stirring system, and obtain the finished product of water-based glue solution for drawing and playing.

[0034] Preferably, in steps (1) and (2), the reaction kettle is dissolved and dispersed at room temperature when the suspending agent and thickening agent are added; to prevent agglomeration at high temperature, which affects the dispersion state. In step (3), cold stirring is performed at room temperature for 10-15 minutes before introducing polyvinyl alcohol, and then gradually increasing the temperature; to avoid agglomeration of the polymer matrix caused by high temperature, and to ensure good flowability and continuity of the glue solution. The temperature control range of 55-65℃ is implemented in the temperature control range of 55-65℃ in the processes of heat preservation and degassing in steps (6) and (7) and the addition of PET flash sheets; after the mixing process is completed, the temperature should be lowered to avoid the phenomenon of flash sheet settlement in a high temperature environment.

[0035] Compared with the prior art, the advantages of the present application are: the water-based tackifying resin and the suspension system are synergistically controlled, achieving a dynamic balance between the adhesive properties and the suspension stability; in the preparation process, the water-based tackifying resin not only provides strong adhesive force and substrate adhesion for the glue, but also forms a three-dimensional network interpenetrating system with the nano-suspension agent. This makes the glue solution form a three-dimensional pseudoplastic fluid structure, which significantly improves the carrying capacity of the suspension agent for PET flash sheets (the suspension density reaches 0.95 g / cm 3), and by precisely regulating the visco-elastic parameters, a differentiated rheological gradient is established in the vertical direction, without affecting the transparency of the system like liquid coatings, and finally the glue solution system has high viscous resistance (viscosity ≥ 40,000 mPa·s) and autonomous suspension characteristics, so that the double-color glue solution forms a zero-permeation barrier at the interface, realizing the stable coexistence of multi-color glue layers in the static storage and dynamic sizing process;

[0036] The particularly introduced pH buffer system controls the pH of the colloid to be between 6.0±0.5, and by regulating the pH of the suspension system, not only the dispersion stability of the colloid is strengthened, but also the carboxyl groups of the tackifying resin are in the best dissociation state, forming a dynamic crosslinking network with pH response, which not only ensures the storage stability of the system, but also realizes the optimized balance of the bonding strength and the flexibility of the glue layer after sizing, so that the glue solution system has good flowability and continuity while having high viscosity and high suspension, and the liquid glue with better transparency also has the writing and marking function like white glue, which is more suitable for manual and bonding application scenarios.

[0037] In addition, the water-based glue solution of the present application also has the characteristics of water-based easy cleaning, good adhesion, good bonding, good moisturizing and anti-freezing performance, bright and clear color, high transparency, good suspension performance, and can be dispersed with the same color, and has good film forming performance., high playability, safety and non-toxicity can be obtained by activating agents such as baking soda and contact lens care solution.

[0085] Comparative Example 1:

[0086] The difference between this comparative example and Example 1 is only that no suspending agent is added in this comparative example.

[0087] Comparative Example 2:

[0088] The difference between this comparative example and Example 1 is only that no pH adjuster is added in this comparative example.

[0089] Comparative Example 3:

[0090] The difference between this comparative example and Example 1 is only that the pH value of the water-based glue system is adjusted to 7.5-8.5.

[0091] Comparative Example 4:

[0092] The difference between this comparative example and Example 1 is only that the suspending agent and thickening agent are not pre-mixed at room temperature during preparation.

[0093] Comparative Example 5:

[0094] The raw materials of the water-based glue solution for drawing and playing in this comparative example include the following components with the following mass percentages:

[0095] 15% polyvinyl alcohol,

[0096] 1.5% glycerol,

[0097] 2% aqueous tackifying resin,

[0098] 1% thickening agent,

[0099] 0.2% pH adjuster,

[0100] 0.2% dyeing agent,

[0101] 1% PET flash sheet,

[0102] 0.3% preservative,

[0103] and the balance of deionized water.

[0104] Among them, the aqueous tackifying resin is an aqueous acrylic resin, the suspending agent is carbomer 940, the thickening agent is hydroxyethyl cellulose, the pH regulator is AMP-95 and sodium bicarbonate, the ratio is 4:1, the dyeing agent is an aqueous rose paste, the PET flash sheet is 1 / 64 multi-color flash powder, and the preservative is MIT.

[0105] Comparative Example 5 increases the ratio of thickening agent to polyvinyl alcohol without adding a suspending agent, to compensate for the lack of a suspension system by adjusting the viscosity of the system.

[0106] The products prepared in Example 1 and Comparative Examples 1-5 were subjected to performance testing, and the testing structure was as follows:

[0107]

[0108] As can be seen from the above table, Example 1 can improve the colloid viscosity by a certain ratio of tackifying resin and polyvinyl alcohol, improve the viscosity, and also significantly improve the freeze resistance of the colloid; in the mutual cooperation of the suspending agent and the thickening agent, the colloid has continuous and smooth coating performance, and the application of the painting scene is more convenient, and the glue solution can maintain stable coexistence of multiple color systems in the system; controlling the pH of the colloid between 6.0±0.5 ensures the storage stability of the system, so that the glue solution system has high viscosity and high suspension, and after coating, the film forming time is shortened, and has good flowability and continuity, which is more convenient and fast in making slime interesting toys.

[0109] In Comparative Example 1, no suspending agent is added, and the system cannot carry the suspension of the PET flash sheet, so that the PET flash sheet in the obtained colloid finally settles at the bottom of the colloid.

[0110] In Comparative Example 2, no pH regulator is added, and in Comparative Example 3, although a pH regulator is added, the pH of the colloid is controlled at 7.5-8.5, and the stability of the system obtained in the two comparative examples is poor, and the two-color interface is easily penetrated and cannot coexist.

[0111] In the preparation process of Comparative Example 4, the suspending agent and the thickening agent are not premixed at room temperature, and are added in the subsequent steps, which causes agglomeration and other phenomena, so that the system has serious gelation, the colloid is discontinuous, and the cold resistance and stability are poor.

[0112] The comparative example 5 increases the ratio of thickening agent to polyvinyl alcohol without adding a suspending agent, so as to compensate for the lack of the suspension system by adjusting the viscosity of the system. The viscosity of the final glue solution system is large, and the bubbles are difficult to eliminate, so that the transparency of the glue is obviously decreased. The increase in viscosity cannot replace the effect of the suspension system, and the glue solution system cannot make the PET glittering powder keep suspended for a long time.

[0113] As shown in Figure 1 , the water-based glue solution prepared in the embodiment 1 is multi-color superimposed and layered and not mutually soluble, and is more beautiful and creative. As shown in Figure 2 , the dyeing agent and the PET glittering sheet type are changed on the basis of the embodiment 1. The coating trace of the obtained product is obvious, the marking effect is significant, and the normal bonding is not affected. As shown in Figure 3 , the dyeing agent and the PET glittering sheet are removed on the basis of the embodiment 1. The glue of the obtained product is uniform and stable, and better transparency is achieved.

[0114] As shown in Figure 4 , it is the coating effect diagram of the comparative example 4. It can be seen that the glue is discontinuous, and the coating performance is poor.

[0115] In summary, the polyvinyl alcohol is used as a core bonding matrix, and an excellent water-based glue solution system is constructed by a composite modification technology. In the basic formula design, the basic bonding characteristics of the polyvinyl alcohol are fully utilized, and the bonding strength (the adhesion is increased by more than 35%) is significantly improved through the molecular level synergistic effect of the water-based tackifying resin. More importantly, the dynamic balance regulation and control of the rheological characteristics of the suspension system and the adhesive performance of the glue are realized. By means of the construction of the three-dimensional pseudoplastic fluid structure, the glue solution system forms a differential rheological gradient (viscosity ≥ 50,000 mPa·s) in the vertical direction, and the suspension density of the PET glittering sheet is successfully increased to 0.95 g / cm 3 . At the same time, through the precise regulation and control of the viscoelastic parameters, the interface barrier of zero permeation is formed under the premise of maintaining the high transparency of the system, so as to ensure the stable separation of the multi-color glue layer in the static storage and dynamic sizing. Specifically, the product obtained by the present application has the following characteristics:

[0116] The intelligent pH regulation mechanism: the pH of the glue solution is precisely controlled at 6.0±0.5 through the self-developed buffer system, which not only ensures the best dissociation degree of the carboxyl group of the tackifying resin and constructs the pH-responsive dynamic crosslinking network, but also significantly enhances the dispersion stability of the glue. The design makes the finished glue solution have high viscosity (>50,000 mPa·s) and self-suspension characteristics, and has excellent flow continuity and film flexibility.

[0117] Multifunctional composite properties: Break through the performance limitations of traditional liquid glue, realize the organic unity of high transparency (transmittance > 92%) and writing and marking functions, and have the characteristics of easy cleaning (water washing removal rate > 98%), weather resistance, anti-freezing, color retention and the like. Through testing, the shear strength of the finished glue liquid reaches 2.8MPa, and the holding adhesion time is more than 72 hours.

[0118] Cross-border application potential: Through modification by specific activators, creative toys with slime properties can be prepared, which have a high thixotropic index and a large tensile deformation rate, and exhibit unique value in the fields of handcrafting and cultural and creative education.

[0119] The technical system successfully fills the market gap of water-based adhesive in the field of paintable functionalization, and the product meets the EN71-3 toy safety standard through SGS detection, providing a better solution for application scenarios such as handcrafting, decoration and adhesion.
