Problems solved by technology

In this ternary system, the PC component can improve the mechanical strength of the alloy, but in the high-temperature molten state, PC and PBT will undergo uncontrollable transesterification reactions, which have very high requirements for the blending process and are an unstable factor.
In addition, the presence of PC increases the melting temperature of the alloy to a certain extent, which is not conducive to the optimization of the processing technology.

[0047] The preparation method of modified nucleating agent comprises the steps:

[0048] Gradually add 50 parts by weight of mineral powder to 50 parts by weight of water, then add 1% acetylacetone of the total weight of the solution, stir until uniform, and slowly add 10 parts by weight of butyl titanate and each Mineral and water weight 1% polycarboxylate sodium salt and titanate coupling agent, after the dropwise addition, continue to stir for 0.5 hours, under the action of acetylacetone, butyl titanate is hydrolyzed to generate titanium dioxide particles, and coated on On the surface of mineral particles, polycarboxylate sodium salt is added as a dispersant, and the surface is modified with a water-based titanate coupling agent. The coated titanium dioxide particles are filtered, dried and pulverized to prepare a modified nucleating agent, which is taken out for use.

Abstract

The invention discloses a PBT (polybutylene terephthalate) zipper material with high modulus and washability and an application of the PBT zipper material in preparation of gold stamped zippers. The PBT zipper material is prepared from raw materials in parts by weight as follows: 50-80 parts of PBT, 15-35 parts of a styrene-butadiene-acrylonitrile copolymer, 1-8 parts of a modified nucleating agent, 1-5 parts of a compatilizer, 1-5 parts of a toughening agent and 0.1-2 parts of a processing aid; the modified nucleating agent comprises a coating structure taking titanium dioxide as a shell andminerals as a core, and the minerals are selected from at least one of talc powder, barium sulfate and sheet mica. The special PBT zipper material has the advantages of high modulus and washability, has excellent processability and cloth adhesion, has appearance and texture of metal zippers and is particularly suitable for preparation of high-end gold stamped zippers.

Description

technical field [0001] The invention relates to the field of zipper preparation, in particular to a high-modulus washable PBT zipper material and its application. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to merge or separate items. It is now widely used in clothing, packaging, tents, etc. According to different materials, it can be divided into metal zippers, nylon zippers and resin zippers. [0003] Resin zipper is another new type of zipper product after metal zipper and nylon zipper. Because it is easy to process, wear-resistant and fatigue-resistant, and its rigidity, elasticity and size are relatively stable, it has become the best substitute for metal zipper. The most widely used type of zipper, but its plastic appearance and texture make it positioned in the low-end market. It is a major development trend of resin zippers to make resin zippers have the texture of metal zippers and increase the ad...
