Embodiment 1

[0018] Add 100 parts of o-phthalic unsaturated polyester resin, 2 parts of styrene, 2 parts of wax water, 1 part of blue color paste, and 1.2 parts of cobalt cyclooctanoate accelerator in the material barrel, stir for 3 minutes, and then add 20 parts of 200-mesh calcium carbonate, continue to stir for 10 minutes, finally add 1.2 parts of methyl ethyl ketone peroxide as a curing agent, stir for 1 minute, pour it into a centrifugal tablet machine (machine speed 20-30r / min), centrifuge and solidify for 50 minutes, take the tablet, and then punch the blank , dipping, button turning, polishing and other processes to obtain button products. The diameter of this button is 18L (1L=0.635mm), and the style is A8603. Air bubbles and shrinkage were not observed during button preparation.

[0019]

Embodiment 2

[0021] With embodiment 1, difference is to select at least one in 100 parts of 200 mesh calcium carbonate, calcium silicate, magnesium carbonate, talcum powder, silicon dioxide, aluminum hydroxide, hollow glass microsphere, cobalt naphthenate accelerator is 1.6 parts, styrene is 6 parts. After adding 1.6 parts of methyl ethyl ketone peroxide as a curing agent, stir for 1 minute, pour it into a centrifugal tablet machine (machine speed 20-30r / min), centrifuge and solidify for 30 minutes, take a tablet, and then go through the processes of punching, soaking, turning, and polishing to obtain buttons. Button products, the diameter of this button is 18L, and the style is A8603.

[0022]

Embodiment 3

[0024] With embodiment 1, the difference is to select at least one of 300 parts of 200 mesh calcium carbonate, calcium silicate, magnesium carbonate, talcum powder, silicon dioxide, aluminum hydroxide, hollow glass microspheres, 1.5 parts of white color paste, 10 Parts of styrene, 4 parts of cobalt naphthenate accelerator, 100 parts of isophthalic unsaturated polyester resin, 4 parts of methyl ethyl ketone peroxide. Add the curing agent methyl ethyl ketone peroxide, stir for 1 minute, then pour it into a centrifugal tablet machine (machine speed 20-30r / min), centrifuge and solidify for 40 minutes, take the tablet, and then go through the processes of punching, soaking, turning buttons, polishing and other processes to obtain button products , the diameter of this button is 18L, and the style is A8603.

Abstract

The invention discloses a preparation method of an unsaturated polyester resin button, comprising the following steps: adding 100 parts of the unsaturated polyester resin, 1-4 parts of inhibitors and 2-10 parts of monomer diluent to a material barrel; adding 20-300 parts of non-organic powder under the stirring state; stirring uniformly; adding 1-4 parts of curing agents; continuously stirring, and pouring on a centrifugal flaker or a roller producing machine; curing at indoor temperature for 20 to 60 min to obtain the blank sheets or rods; flushing the blanks, cutting and dipping the blanks, mechanically twisting and polishing to obtain the button product. The invention reduces the use quantity of the unsaturated polyester resin, indirectly reduces the use of petroleum-based materials, and has simple process and low cost. The prepared product has excellent mechanical property.

Description

technical field [0001] The invention relates to the button technology of clothing accessories, in particular to an unsaturated polyester resin button and a preparation method thereof. Background technique [0002] Usually prepared polyester buttons are made of unsaturated polyester resin as the main raw material, adding appropriate amount of additives, gelling in specific equipment and molds, curing into pearlescent or non-pearlescent plates / rods, and then mechanically processed. . Unsaturated polyester resin buttons have the characteristics of acid and alkali resistance and high temperature washing and ironing. They are rich in color changes and have excellent physical and chemical properties. They are widely used in clothing accessories and are the leading products of clothing buttons. [0003] The main raw material used in the preparation of polyester buttons is unsaturated polyester resin, which is prepared from petroleum-based materials such as unsaturated dibasic acid...
