Embodiment 1

[0039] Embodiment 1: A kind of organic carboxylate nucleating agent, each component and its corresponding parts by weight are as shown in Table 1, and are prepared through the following steps:

[0040] Step 1, dissolve and mix the corresponding parts by weight of p-tert-butylbenzoic acid, water and n-butanol evenly for 0.5h, then add NaAlO 2 With the sodium hydroxide of 1 / 2 corresponding parts by weight, carry out neutralization reaction 0.6h;

[0041]Step 2, followed by adding the corresponding parts by weight of aluminum chloride hexahydrate, after reacting for 2 hours, press filtration to remove the hazardous waste liquid, and after circulating water washing for 3 times, then add the remaining parts by weight of sodium hydroxide, press filter Remove chloride ions to obtain a mixture;

[0042] Step 3: Add corresponding parts by weight of citric acid into the mixture, stir for 1.5 hours, distill under reduced pressure, and perform vacuum drying to obtain an organic carboxyla...

Embodiment 2-8

[0044] Example 2-8: An organic carboxylate nucleating agent, the difference from Example 1 is that each component and its corresponding parts by weight are shown in Table 1.

[0045] Each component and parts by weight thereof in table 1 embodiment 1-8

[0046]

Embodiment 9

[0047] Embodiment 9: a kind of organic carboxylate nucleating agent, the difference from embodiment 1 is that step one is specifically set as, the corresponding parts by weight are 130 parts of p-tert-butylbenzoic acid, 350 parts of Water and 90 parts of n-butanol are dissolved and mixed evenly, and the time is 0.5h, and then 20 parts of KAlO are added 2 And 9 parts of sodium hydroxide, carry out neutralization reaction 0.6h.

Abstract

The invention discloses an organic carboxylate nucleating agent and a preparation process thereof, relates to the technical field of nucleating agents, and solves the problem of the overall application effect of the nucleating agent due to its poor dispersibility when compounded and used Poor question. An organic carboxylate nucleating agent, which comprises the following components in parts by weight: 130-150 parts of p-tert-butylbenzoic acid; 4-5 parts of aluminum chloride hexahydrate; 20-30 parts of metaaluminate 350-450 parts of water; 60-90 parts of organic solvent; 18-26 parts of sodium hydroxide; 4-8 parts of citric acid. The organic carboxylate nucleating agent in the present invention has good dispersibility when compounded and used, can volatilize a good and stable nucleating effect, and has a good application effect as a whole.

Description

technical field [0001] The invention relates to the technical field of nucleating agents, more specifically, it relates to an organic carboxylate nucleating agent and a preparation process thereof. Background technique [0002] Nucleating agents are additives suitable for polymers, especially incompletely crystalline polymers, such as polyethylene and polypropylene, etc., and used to modify their crystallization behavior. The nucleating agent can shorten the molding cycle and improve the transparency, surface gloss, tensile strength, rigidity, heat distortion temperature, impact resistance and creep resistance of the product by accelerating the crystallization rate, increasing the crystallization density and promoting the miniaturization of the grain size. Denaturation and other properties. [0003] The Chinese invention application document with the publication number CN105348310A discloses the preparation method of the nucleating agent, which is prepared by the chemical r...
