Description

A double-sided adhesive foam block suitable for fixing the posture and position of butterfly specimens

technical field

The invention belongs to the technical field of tools for laboratories or specimen exhibition rooms, and in particular relates to a double-sided adhesive foam block suitable for fixing the posture and position of butterfly specimens.

Background technique

Butterfly specimens are an important tool for classifying butterflies, watching butterflies, and researching and understanding a series of disciplines of butterflies. It takes a lot of time to fix the specimen box with viscous glue, and keep adjusting the posture while the glue is not yet condensed, and strive to make the main perspective and the top perspective of the finished specimen achieve a symmetrical visual effect. In order to solve the shortcomings of the existing methods and shorten the time spent on fixing the posture and position of the butterfly specimens in the production process, a double-sided adhesive foam block suitable for the posture and position of the butterfly specimens is proposed, which can easily fix the butterfly specimens that have finished spreading their wings After being placed on the foam block, correct the position of the foam block and fix it in the specimen box. Due to the verticality of the groove and the main viewing angle, and the support of the butterfly wings by the two wings of the groove, the specimen can achieve a symmetrical visual effect in both the main viewing angle and the top viewing angle of the finished product.

Contents of the invention

The purpose of the present invention is to solve the deficiencies in the prior art, to provide a double-sided adhesive tape that can shorten the time for fixing the position of the butterfly specimen, and ensure that the butterfly specimen with wings spread can achieve the symmetrical effect of the main angle of view and the angle of view when the posture and position are fixed. The foam block is conducive to the display and viewing of butterfly specimens in the specimen box, avoiding the position of butterfly specimens in the specimen box from skewing and tilting, and can also be quickly fixed on any vertical surface that can be attached by pressure-sensitive adhesive.

Technical scheme of the present invention:

A double-sided adhesive foam block suitable for fixing the posture and position of butterfly specimens, comprising a foam block 1 with grooves, a groove layer release paper 2, a groove layer pressure-sensitive adhesive 3, a lower layer pressure-sensitive adhesive 4 and Lower release paper 5;

The material of the foam block 1 with grooves is EVA resin (ethylene-vinyl acetate copolymer), which is a straight quadrangular prism structure with a grooved isosceles trapezoid as the bottom surface, and the length of its base is 2cm, wide The diameter of the groove is 1cm; the diameter of the groove is determined according to the diameter of the chest section of the butterfly, which is 3mm to 10mm; the thickness of the double-sided adhesive foam block in the height direction is 1.5 times the radius of the groove;

The groove layer release paper 2 and the lower layer release paper 5 are both single-silicon white release paper, consisting of a three-layer structure: the first layer is the bottom paper, the second layer is the coating, and the third layer is silicone oil ; The composition of the groove layer pressure-sensitive adhesive 3 and the lower layer pressure-sensitive adhesive 4 is a resinous polyacrylate copolymer adhesive; the groove layer release paper 2 and the lower layer release paper 5 pass through the groove layer respectively The pressure-sensitive adhesive 3 and the lower-layer pressure-sensitive adhesive 4 are fixed in the groove of the double-sided adhesive foam block and the base of the double-sided adhesive foam block.

The groove sides of the two wings of the groove change in position with the groove radius, and are parallel to the horizontal plane or at an obtuse angle of 170°, making the butterfly specimen more ornamental.

The groove is a half-pipe structure, and its direction is parallel to the width direction of the foam block 1 with grooves.

The beneficial effect of the present invention is that it shortens the adjustment time for butterfly specimens to achieve symmetry when the attitude and position are fixed; it also enables the butterfly specimens to be easily attached to the vertical surface that can be attached by pressure-sensitive adhesive, and is not easy to fall off.

Detailed ways

The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

A double-sided adhesive foam block suitable for fixing the posture and position of butterfly specimens, including a foam block 1 with grooves, the foam block with grooves is coated with groove layer pressure-sensitive adhesive 3, and the grooves are The surface of the pressure-sensitive adhesive is protected by a layer of grooved release paper 2 to prevent the pressure-sensitive adhesive from adhering to debris before use and losing its viscosity.

As shown in Figures 1 to 3, the base of the grooved foam block is coated with a lower pressure-sensitive adhesive 4, and the surface of the lower pressure-sensitive adhesive is protected by a lower layer of release paper 5 to prevent the pressure-sensitive adhesive from sticking before use The debris loses its stickiness.

Hold the middle part of the butterfly’s wings with tweezers after the wings have been spread, and choose double-sided adhesive foam blocks with different groove diameters according to the different diameters of the butterfly’s thoracic cross-section, so that the legs and feet of the butterfly specimen can be removed or retained. Tear off the release paper 5 on the lower layer of the double-sided adhesive foam block, and put the double-sided adhesive foam block into the specimen box. Parallel to each other, lightly press the two wings of the double-sided adhesive foam block groove to ensure that the foam block is well fixed. Tear off the release paper 2 of the groove layer of the double-sided adhesive foam block, place the chest section of the butterfly specimen in the direction parallel to the groove, and put it down toward the pressure-sensitive adhesive layer 3 of the groove layer, and lightly press the back of the chest section of the butterfly specimen to ensure that it is in good condition .

Or hold the butterfly specimen with tweezers in the middle of the butterfly's wing, and choose double-sided adhesive foam blocks with different groove diameters according to the different diameters of the butterfly's chest cavity to remove or retain the legs and feet of the butterfly specimen. Tear off the release paper 2 of the groove layer of the double-sided adhesive foam block, place the chest section of the butterfly specimen facing the parallel direction of the groove, and place it on the pressure-sensitive adhesive 3 of the groove layer, and lightly press the back of the butterfly specimen to ensure that it is well fixed. Then tear off the release paper 5 of the lower layer of the double-sided adhesive foam block, hold the middle part of the butterfly wing with tweezers, choose any inclination angle and any position according to the decoration requirements, and stick it on the display wall that can be adhered by pressure-sensitive adhesive On the top, lightly press on the back of the thoracic section of the butterfly specimen to ensure good fixation.

The groove is a semi-tubular structure with a direction parallel to the width of the foam block. Since the cross-section of the part below the wings of the butterfly specimen chest is close to a semicircular structure, it is designed to be semi-tubular so that the butterfly specimen can fit better with the double-sided adhesive foam block.

The overall structure of the double-sided adhesive foam block is a straight quadrangular prism structure with semi-tubular grooves and an isosceles trapezoidal bottom surface. Visually, the quadrangular prism has the largest side area as the base and is laid flat. It is designed as a straight quadrangular prism structure, so that it is convenient to hold the side parts of the prism at the two waists of the isosceles trapezoid by hand during operation.

The length of the grooved layer release paper and the lower layer of release paper is 2mm longer than the area of the pressure-sensitive adhesive to be protected. The purpose is to facilitate tearing off the extra part when using the double-sided adhesive foam block Release paper.
