Problems solved by technology

At the same time, the traditional polymer stabilizer is often a compound physical addition of Cyclone, because Cyclone contains three hydroxyl groups, it is very soluble in water and incompatible with polymers. When the amount is large, it will cause precipitation and polymerization on the surface of plastic products. The volume resistivity of the object decreases, which seriously damages the interests of product companies

preparation example Construction

[0034] A kind of preparation method of Sike phosphite alcohol ester of the present invention comprises the following steps: Step 1, add triethyl phosphite, Sike, catalyst in the same reaction kettle, heat reaction 1-3 hour, reaction temperature is 80- At 130°C, the ethanol produced by the reaction was discharged to obtain substance A;

[0035] Step 2, adding alcohols to the reaction kettle, reacting with the phosphorus and nitrogen in the substance A to form a triazine ring structure;

[0036] Step 3: After the reaction in Step 2 is complete, the reaction kettle is heated to remove excess alcohol to obtain the finished product of Cyke phosphite alcohol ester.

[0037] Wherein, the triethyl phosphite: Saike: the mol ratio of alcohols is 1:1:X;

[0038] The alcohols are monohydric linear alcohols, and the X=1-1.2;

[0039] The alcohols are binary linear alcohols, and the X=0.5-0.7;

[0040] The alcohols are pentaerythritol, and the X=0.25-0.4.

[0041] Based on the degree of...

Embodiment 1

[0065] Example 1: Cyke lauryl phosphite

[0066] Add 277 kilograms of triethyl phosphite, 437 kilograms of saike, and 14 kilograms of phosphoric acid in the reaction kettle equipped with stirring and temperature controller, heating coil, condenser and collection bottle, and heat to 100 ° C for 1 hour.

Abstract

The invention discloses a preparation method of tri(2-hydroxyethyl) isocyanurate-phosphite alcohol ester. The method comprises the following steps: step 1, adding triethyl phosphite, tri(2-hydroxyethyl) isocyanurate and a catalyst into a reaction kettle, carrying out a heating reaction for 1 to 3 hours at a reaction temperature of 80 to 130 DEG C, and discharging ethanol generated by the reactionso as to obtain a substance A; 2, adding alcohols into the reaction kettle, and performing a reaction with phosphorus and nitrogen in the substance A to generate a triazine ring structure; and step 3,after the reaction in the step 2 is completed, heating the reaction kettle until redundant alcohol is removed to obtain a finished product of the tri(2-hydroxyethyl) isocyanurate-phosphite alcohol ester. According to the polymer heat stabilizer provided by the invention, the tri(2-hydroxyethyl) isocyanurate is fully reacted to produce water-insoluble ester with larger molecular weight, so that the polymer product is good in compatibility and not easy to separate out, and the volume resistivity is not influenced.

Description

technical field [0001] The invention relates to the technical field of heat stabilization, specifically referring to a kind of Cyke phosphite alcohol ester and its preparation method and application. Background technique [0002] Phosphite is an important secondary antioxidant in plastic polymers. At present, phosphites containing phenols are not required to be used in plastic polymers such as medical, toys, and home furnishing. Traditional phenolic phosphites have strong thermal stability. At present, the structure of phenol-free phosphites mainly uses fatty alcohols instead of phenols, such as commercially available triheptyl phosphite, triisodecyl phosphite, phosphorous acid Trilauryl, tristearyl phosphite, etc. This type of phosphite is not thermally stable because of its low phosphorus content and only straight-chain fatty alcohols. In some cases, the chain fatty alcohol contained in the polymer formula is unnecessary or avoided, for example, it is easy to cause exce...
