Description

Adhesive mixing manufacturing apparatus for furniture, floorboards and indoor interior panels {Manufacturing equipment for mixing adhesives for furniture floorboards or indoor interior panels}

The present invention relates to an adhesive and an adhesive used for panels of furniture, floorboards, and interiors, and more particularly, it is possible to prevent film formation and solidification due to a change in physical properties while mixing the adhesive, and to provide furniture or floorboards. , It relates to an adhesive formulation manufacturing apparatus for furniture, floorboards, and interior interior panels that can maintain optimal adhesive strength for interior panels.

Advances in science and technology require various functionalities and strengths of materials, and since it is difficult to solve this problem with a single material, materials that combine conventional materials are being developed.

The conventional materials used here are adhesive sheets or adhesives, and various metals and organic materials, fibers, plastics, rubber ceramics, etc. are being developed as new materials through adhesive sheets or adhesives.

Adhesives are divided into solvent-type and non-solvent-type adhesives using organic solvents depending on the production type.

Recently, as interest in chemicals that can cause environmental problems increases, attention is focused on adhesive sheets or adhesives related to the environment.

Environmental problems that may occur due to adhesives include the generation of volatile organic solvents (VOC) due to the use of solvent-type adhesive sheets or adhesives, and volatilization of unreacted monomers inside the adhesive sheets or adhesives.

In order to solve this problem, a solvent-free adhesive that does not use an organic solvent has been developed, and a water-soluble adhesive is a representative solvent-free adhesive.

However, the water-soluble adhesive on the market has improved the environmental pollution problem compared to the conventional adhesive causing environmental problems, but has a problem in that it is insufficient in physical properties such as adhesion.

Accordingly, the development of a water-soluble adhesive to improve these problems is required.

Adhesive can be manufactured by providing the adhesive compounding manufacturing apparatus for furniture, floorboard, and indoor interior panel 2 configured as described above.

Here, the adhesive is a composition described in Patent Registration No. 10-1909878, previously applied and registered by the present applicant, and constitutes the adhesive, or ethylene vinyl acetate (EVA) resin, polyvinyl alcohol (PVA), water, calcium carbonate, a main agent consisting of a surfactant and a thixotropic agent; An adhesive composed of a curing agent composed of an isocyanate compound can be used, and in particular, in the case of the above subject, 30 to 90 parts by weight of ethylene vinyl acetate (EVA) resin, 1 to 30 parts by weight of polyvinyl alcohol (PVA), 10 to 30 parts by weight of water, 5 to 30 parts by weight of calcium carbonate, 0.1 to 1 parts by weight of a surfactant, and 1 to 20 parts by weight of a thixotropic agent, and in the case of the curing agent, 5 to 15 parts by weight of an isocyanate compound based on 100 parts by weight of an ethylene vinyl acetate (EVA) resin It may consist of parts.

On the other hand, according to the test report (AK-2020-005425) tested by the Korea Chemical Convergence Testing Laboratory, the curing (solidification) of the adhesive when 0, 5, 10, and 15 parts by weight of the crosslinking agent are added to the subject as shown in Table 1 below. ) can be confirmed numerically.

[Table 1]

As can be seen from the results according to the above experiment, when the crosslinking agent is not added, the result is 591, which is favorable for liquefaction, and when 15 parts by weight of the crosslinking agent is added, the result is 1373, which shows that the physical property is high, which is advantageous for solidification.

In other words, when the amount of isocyanate added as a crosslinking agent is 10 parts by weight or less, the physical properties are low, so it can be used as an instant adhesive to be used when necessary in a liquid form, and there is a problem that the shape cannot be maintained, and the isocyanate added as a crosslinking agent is When it is 10 parts by weight or more, it has ease of use due to solidification like jelly, but there is a difficulty in transforming into another shape after forming the initial adhesive shape.

Therefore, it can be said that the addition of the crosslinking agent in an amount of 5 to 15 parts by weight as shown in Table 1 is a very important requirement to increase the adhesive strength of the adhesive. When used as an adhesive applied to the panel (2) of , it can be said that an adhesive provided by adding 10 parts by weight out of 5 to 15 parts by weight of the crosslinking agent is most suitable.

Therefore, by suggesting the composition of the adhesive compounding manufacturing apparatus of the present invention configured as described above, that is, the adhesive compounding manufacturing apparatus shown in FIGS. It has the effect of maintaining the optimum adhesive strength for furniture, floorboards, and interior panels.
