Formaldehyde-free high-viscosity adhesive for plate edge sealing, production device and preparation method thereof

Abstract

The invention discloses a formaldehyde-free high-viscosity adhesive for edge sealing of plates, and a production device and a preparation method thereof, which relate to the technical field of adhesives and include a frame. The invention uses an eccentric rotating mechanism to rotate a fiber dual-state crushing and mixing mechanism inside a processing box. When the eccentric rotating mechanism drives the central shaft to rotate at a slow speed, the central shaft drives a plurality of annular equidistantly arranged protrusions to drive the crushing and mixing components to rotate through elastic connecting parts. At this time, since the centrifugal force is less than the elasticity of the elastic connecting parts, the crushing and mixing components rotate in a flower shape, achieving a uniform mixing effect. When the eccentric rotating mechanism drives the central shaft to rotate at a fast speed, when the centrifugal force is greater than the elasticity of the elastic connecting parts, the crushing and mixing components are in an open shape, which is used for extruding and crushing cellulose fiber raw materials. The invention pre-treats the raw materials with the formaldehyde-free high-viscosity adhesive added with cellulose fibers, so that the prepared adhesive has a good modification and enhancement effect, and does not require frequent machine replacement, so the production efficiency is high.

Description

Technical Field

[0001] The present invention relates to the technical field of adhesives, and more specifically to a formaldehyde-free high-viscosity adhesive for edge sealing of panels, and a production device and a preparation method thereof. Background Art

[0002] Among the formulation explorations of many formaldehyde-free adhesives, cellulose fiber has been widely studied and applied to improve the strength and environmental performance of adhesives due to its excellent thickening, water retention and biodegradability. It is very suitable for use as a large amount of adhesive in the edge banding of boards to improve the environmental performance and physical properties of boards. As a natural polymer material, cellulose fiber has its own characteristics, such as natural hydrophilicity, excellent grip, huge fiber specific surface area, and high toughness and strength. After being added to the adhesive, a large number of evenly distributed fine fibers are formed under the immersion of the colloid and the action of external forces, which can effectively prevent the plastic shrinkage of the adhesive, shrinkage and temperature changes that cause cracks. Therefore, adding cellulose fiber to the adhesive formula can not only enhance the physical properties of the adhesive, but also improve its processability and the texture of the final product to a certain extent. However, in the actual production process, the introduction of cellulose fiber faces a series of technical challenges.

[0003] First, cellulose fibers usually exist in the form of sheets, and their large specific surface area and strong hydrogen bonding between each other make it difficult to disperse evenly in water-based or solvent-based adhesives. Directly or in batches, adding untreated cellulose fibers to a stirring device often leads to fiber agglomeration and uneven dispersion, which in turn affects the final performance of the adhesive, such as reducing its viscosity, bonding strength and water resistance.

[0004] Secondly, most adhesive production equipment on the market currently focuses on the mixing and reaction control of raw materials, and lacks modules for effective pretreatment of specific additives such as cellulose fibers. This makes it difficult to fully expand, disperse and modify cellulose fibers before adding them to the reaction system, making it difficult to achieve the desired reinforcement effect.

[0005] In summary, it is particularly important to develop a new production device that integrates cellulose fiber pretreatment and formaldehyde-free high-viscosity adhesive production. In view of this, we propose a formaldehyde-free high-viscosity adhesive for board edge sealing and its production device and preparation method. Summary of the invention

[0017] Preferably, the present invention provides a method of use, comprising the following steps:

[0018] S1, feeding operation;

[0019] The cellulose fiber raw material enters the feed pipe through the feed port. At this time, the servo motor drives the auger rod to rotate in the feed pipe, and the auger rod allows the cellulose fiber raw material to enter the processing box through the feed pipe and the inspection door panel;

[0020] S2, valve closing operation;

[0021] The slide block is driven to slide on the slide groove by the cylinder stroke. When the slide block slides, the limit rod inserted in the limit groove rotates. Since the limit rods of the turntable A and the turntable B are arranged in opposite directions, the two limit rods respectively drive the turntable A and the turntable B to rotate in opposite directions, so that the shaft rod fixedly connected to the turntable A and the sleeve fixedly connected to the turntable B are respectively driven to rotate. The rotation of the shaft rod and the sleeve causes the fan blades A and the fan blades B to rotate, thereby realizing the closing function, so that the cellulose fiber raw materials injected into the processing box are blocked;

[0022] S3, pre-processing operation;

[0023] S3.1. According to the need for mixing or crushing, the specific speed of the reduction motor is selected. If the cellulose fiber raw material and other raw materials need to be mixed, the reduction motor is driven to rotate at a low speed, and the output end of the reduction motor drives the eccentric block connected eccentrically to rotate. The eccentric block drives the fiber dual-state crushing and mixing mechanism to rotate eccentrically inside the processing box. The central axis drives a number of convex blocks arranged at equal intervals in an annular manner to drive the crushing and mixing assembly to rotate as a whole through the elastic connecting piece. At this time, due to the elastic tension of the elastic connecting piece, the pulling groove is pulled to bend the hinge of the telescopic connecting rod A and the telescopic connecting rod B, and the whole is in a flower shape, which is used for mixing and stirring the cellulose fiber and the other powders evenly;

[0024] S3.2. According to the need for mixing or crushing, the specific speed of the reduction motor is selected. If the cellulose fiber raw material needs to be crushed, the reduction motor is driven to rotate at a high speed, and the output end of the reduction motor drives the eccentric block connected eccentrically to rotate, and the eccentric block drives the fiber dual-state crushing and mixing mechanism to rotate eccentrically inside the processing box. When the centrifugal force is greater than the elastic tension of the elastic connecting piece, the hinge of the telescopic link A and the telescopic link B is centrifugally thrown out, and several groups of telescopic links A and telescopic links B are in a circular shape as a whole. When the telescopic link A and the telescopic link B are stretched to the longest state, the repair plate that is movably engaged in the active card slot is synchronously thrown out through the engaging rod, so that the outer wall forms a full circle, and the outer wall of the full circle shape and the inner wall of the processing box fully squeeze the cellulose fiber raw material to crush it;

[0025] S4, discharging operation;

[0026] The slide block is driven to slide on the slide groove by the cylinder stroke. When the slide block slides, the limit rod inserted in the limit groove rotates. Since the limit rods of turntable A and turntable B are set in opposite directions, the two limit rods respectively drive turntable A and turntable B to rotate in opposite directions, causing the shaft rod fixedly connected to turntable A and the sleeve fixedly connected to turntable B to rotate respectively. The rotation of the shaft rod and the sleeve causes the fan blades A and the fan blades B to rotate, thereby realizing opening. The pretreated cellulose fibers are discharged through the discharge pipe for subsequent production steps.

[0027] A formaldehyde-free high-viscosity adhesive for edge sealing of a board comprises: 100 parts of a PAE resin aqueous solution, 40 parts of high-temperature soybean meal powder, 20 parts of a carboxylated styrene butadiene emulsion, 0.8 parts of a tackifier, 0.8 parts of sodium hexametaphosphate, 0.8 parts of a wetting agent, 0.8 parts of a defoaming agent, 1.2 parts of a dispersant, and 10 parts of cellulose fibers.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention is provided with a protective shell on the frame, and an eccentric rotating mechanism is provided at a position of the protective shell near the rotating hole. A processing box is fixedly provided inside the protective shell, and the eccentric rotating mechanism is rotatably inserted in the processing box. A fiber dual-state crushing and mixing mechanism is connected to the eccentric rotating mechanism, and the fiber dual-state crushing and mixing mechanism is rotated inside the processing box through the eccentric rotating mechanism. When the eccentric rotating mechanism drives the central shaft to rotate slowly, the central shaft drives a number of annular equidistantly arranged protrusions to drive the crushing and mixing components to rotate through elastic connecting parts. At this time, since the centrifugal force is less than the elasticity of the elastic connecting parts, the crushing and mixing components rotate in a flower shape, which has the effect of uniform mixing. When the eccentric rotating mechanism drives the central shaft to rotate quickly, when the centrifugal force is greater than the elasticity of the elastic connecting parts, the crushing and mixing components are in an open shape, which is used for extruding and crushing cellulose fiber raw materials. The present invention pre-treats the raw materials with formaldehyde-free high-viscosity adhesive added with cellulose fiber, so that the prepared adhesive has good modification and enhancement effect, and does not need to frequently replace the machine, so the production efficiency is high.

[0030] 2. In the present invention, the slider is driven to slide on the slide groove through the cylinder stroke return stroke. When the slider slides, the limit rod slidably inserted in the limit groove rotates. Since the limit rods of turntable A and turntable B are set in opposite directions, the two limit rods respectively drive turntable A and turntable B to rotate in opposite directions, causing the shaft rod fixedly connected to turntable A and the sleeve fixedly connected to turntable B to rotate respectively. The rotation of the shaft rod and the sleeve causes the fan blades A and the fan blades B to rotate, realizing the opening and closing functions. This blocks the cellulose fiber raw materials injected into the processing box when the crushing and mixing assembly is mixed or crushed, and opens to enter the next production step after the pretreatment is completed, further improving the fineness of the raw material pretreatment.

[0031] 3. In the present invention, the output end of the driving reduction motor drives the eccentric block connected eccentrically to rotate, and the eccentric block drives the fiber dual-state crushing and mixing mechanism to rotate eccentrically inside the processing box. When the eccentric rotating mechanism drives the central shaft to rotate slowly, the central shaft drives a number of convex blocks arranged at equal intervals in an annular manner to drive the crushing and mixing assembly to rotate as a whole through the elastic connecting piece. At this time, due to the elastic tension of the elastic connecting piece, the pulling groove is pulled to bend the hinge of the telescopic connecting rod A and the telescopic connecting rod B, and the whole is in a flower shape, which is used for mixing and stirring the cellulose fiber and the rest of the powder evenly. When the eccentric rotating mechanism drives the central shaft to rotate slowly, the central shaft drives the plurality of convex blocks arranged at equal intervals in an annular manner to drive the crushing and mixing assembly as a whole through the elastic connecting piece. When the rotation speed of the middle shaft is fast, when the centrifugal force is greater than the elastic pulling force of the elastic connecting piece, the hinge of the telescopic link A and the telescopic link B is centrifugally thrown out, and several groups of telescopic links A and telescopic links B are circular in shape as a whole. When the telescopic links A and telescopic links B are stretched to the longest state, the repair plate that is movably engaged in the movable slot is synchronously thrown out through the engaging rod, causing the outer wall to form a full circle. The full circular outer wall and the inner wall of the processing box fully squeeze the cellulose fiber raw material to crush it, further improving its crushing efficiency, thereby improving the overall production efficiency.

[0058] The fiber dual-state mixing mechanism 8 includes a central axis 801, a protrusion 802, an elastic connector 803, a mixing assembly 804 and a sliding assembly 805. The central axis 801 is connected to the eccentric rotating mechanism 6, the protrusions 802 are arranged in a ring-shaped and equidistant manner on the outer wall of the central axis 801, the mixing assembly 804 is connected to several protrusions 802 through the elastic connector 803, and the sliding assembly 805 is slidably arranged on the outer wall of the mixing assembly 804.

The mixing component 804 rotates. At this time, since the centrifugal force is less than the elasticity of the elastic connecting member 803, the crushing and mixing component 804 rotates in a flower shape, which has the effect of uniform mixing. When the eccentric rotating mechanism 6 drives the central axis 801 to rotate at a faster speed and the centrifugal force is greater than the elasticity of the elastic connecting member 803, the crushing and mixing component 804 is in an open state, which is used to extrude and crush the cellulose fiber raw material.

In the present invention, the reduction motor 602 is driven to rotate, and the output end of the reduction motor 602 drives the eccentrically connected eccentric block 603 to rotate, and the eccentric block 603 drives the fiber dual-state crushing and mixing mechanism 8 to rotate eccentrically inside the processing box 7. When the eccentric rotating mechanism 6 drives the central axis 801 to rotate slowly, the central axis 801 drives a number of annular equidistantly arranged protrusions 802 to drive the crushing and mixing component 804 to rotate through the elastic connecting piece 803. At this time, since the centrifugal force is less than the elasticity of the elastic connecting piece 803, the crushing and mixing component 804 rotates in a flower shape, which has the effect of uniform mixing. When the eccentric rotating mechanism 6 drives the central axis 801 to rotate quickly, when the centrifugal force is greater than the elasticity of the elastic connecting piece 803, the crushing and mixing component 804 is in an open state, which is used to extrude and crush the cellulose fiber raw material, thereby improving the subsequent fusion efficiency, so as to achieve efficient and stable production of formaldehyde-free high-viscosity adhesives.
