Problems solved by technology

When the nano-montmorillonite is dispersed in the resin, the montmorillonite sheet will accumulate on the surface of the material along with the gasified resin, forming a denser carbon layer, which reduces the heat release rate of the resin.

Embodiment 1

[0015] Example 1: Take 10 g of nano-montmorillonite and disperse it in 50% (weight) ethanol aqueous solution to make a solution with a concentration of 0.048 g / ml, then add 3.28 g of γ-aminopropyltriethoxysilane, and reflux at 70 ° C 24h, rotary steamed to 50ml to obtain amino-modified nano-montmorillonite, and then another 6.18g of 2,2'-methylene-bis(4,6-di-tert-butylphenol) phosphorus oxychloride was dissolved in 50ml of absolute ethanol Add amino-modified nano-montmorillonite, stir at 50°C for 3 hours, filter, wash, and vacuum-dry to obtain nano-montmorillonite-modified organophosphate nucleating agent. The obtained nucleating agent has good nucleating effect, and has the functions of flame retardancy and gas barrier.

[0016] The infrared spectra of nano-montmorillonite, amino-modified nano-montmorillonite, organophosphorus oxychloride and modified organophosphate are as follows: figure 1 As shown, the amino-modified nano-montmorillonite has a wave number of 1080cm -1 Si...

Abstract

The present invention discloses a preparation method for a nano-montmorillonite modified organophosphate nucleating agent. The method comprises the following steps: dispersing nano-montmorillonite in an aqueous solution of ethanol; adding a silane coupling agent; carrying out refluxing under a heating condition to obtain amino-modified nano-montmorillonite; adding a 2,2'-methylene-bis(4,6-di-tert-butylphenol)phosphoryl chloride solution, and stirring; after completing the reaction, carrying out treatments of filtering, washing and vacuum drying to obtain the nano-montmorillonite modified organophosphate nucleating agent. According to the present invention, the organophosphate is linked on the surface of the nano-montmorillonite by chemical bonds so as to effectively reduce the agglomeration of the organophosphate in the resin matrix, and enhance the dispersity of the organophosphate in the matrix, such that the heterogeneous nucleation effect of the nucleating agent can be effectively provided; with the introduction of the inorganic nano-montmorillonite, thermal stability and various mechanical properties of the material can be further improved.

Description

technical field [0001] The invention relates to the technical field of organophosphate nucleating agents, in particular to a preparation method of a nano-montmorillonite-modified organophosphate nucleating agent. Background technique [0002] Organophosphate nucleating agents are widely used in the processing of high crystallinity polypropylene, which can endow products with higher transparency, rigidity and heat distortion temperature. Organophosphate nucleating agents mainly include phosphate metal salts and Phosphate ester basic metal salts and their complexes, etc. These products can also be divided into three generations. The first generation of products came out in the early 1980s, represented by NA-10 of Japan Asahi Denka; the second generation of products was NA-11 launched by Asahi Denka in the mid-1980s, and its nucleation performance was better than that of NA- 10. When the compounding amount is less than 0.1%, the stiffening effect is even higher than that of so...
