Abstract

The invention relates to the technical field of liquid stabilizers and in particular relates to a barium-zinc liquid stabilizer and a preparation method thereof. The barium-zinc liquid stabilizer is characterized by being prepared from the following raw materials in percentage by weight: 20-35 percent of isocaprylic acid, 10-15.5 percent of oleic acid, 8.5-12.8 percent of barium hydroxide monohydrate, 1-5 percent of zinc oxide, 5-10.5 percent of diethylene glycol monobutyl ether, 1-3 percent of synthetic antioxidant, 1-3 percent of metal deactivator and 1.5-2.5 percent of beta-diketone. Compared with the prior art, the barium-zinc liquid stabilizer has the advantages that the formula contains multiple antioxidants, the proportion of the component is optimized and reasonable, for the polyvinyl chloride (PVC) products, the excellent thermal stability and transparency, the initial stainability, weather resistance, ageing resistance, printing property, durability, invariant color and other excellent performances can be kept, the environment-friendly requirements are met, and the barium-zinc liquid stabilizer has the characteristics of excellent performance, low production cost and the like and is suitable for popularization and application.

Description

A kind of barium-zinc liquid stabilizer and preparation method thereof

Technical field

The present invention relates to the liquid stabilisers technical field, relate in particular to a kind of barium-zinc liquid stabilizer and preparation method thereof.

Background technology

The importance of barium-zinc liquid stabilizer system day by day increases, it is of a great variety to supply the ba/zn liquid stabilisers in the market, almost can be used for all areas from the semi-rigid product to plasticized PVC, comprise calendering, extrude, the processing of injection moulding extrusion-blown modling, injection moulding blowing and plastisol.

But existing barium-zinc liquid stabilizer also is not fully up to expectations fully on weathering resistance, ageing resistance, thermostability.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, improve prescription and proportioning each component is more optimized rationally, guarantee the performance of PVC goods.

For achieving the above object, the present invention designs a kind of barium-zinc liquid stabilizer, it is characterized in that adopting the feedstock production of following weight ratio to form:

Isocaprylic acid: 20%～35%;

Oleic acid: 10%～15.5%;

Barium monohydrate: 8.5%～12.8%;

Zinc oxide: 1%～5%;

Diethylene Glycol butyl ether: 5%～10.5%;

Comprehensive oxidation inhibitor: 1%～3%;

Metal passivator: 1%～3%;

Beta-diketon: 1.5%～2.5%;

Anti-precipitation agent: 5%～10.5%;

DOP：20%～35%，

Described comprehensive antioxidant be AO20 antioxidant, AO30 antioxidant, AO40 antioxidant, AO50 antioxidant, 168 antioxidants by etc. weight ratio mix.

Described metal passivator is N, N'-two salicylidene propylene diamine.

A kind of preparation method of barium-zinc liquid stabilizer, it is characterized in that adopting and be prepared as follows step: (1) is put into the Diethylene Glycol butyl ether of isocaprylic acid, oleic acid, barium monohydrate, zinc oxide and half amount in the reactor successively, stirring is warming up to 80～90 ℃, and be incubated to complete reaction with this temperature, solution becomes is transparent; (2) be warming up to 100～110 ℃, carry out vacuum hydro-extraction; (3) add comprehensive antioxidant, metal passivator, β more successively--diketone, anti-precipitation agent, DOP and remaining Diethylene Glycol butyl ether, stir under 115～25 ℃ of temperature and got product in 0.5～2 hour.

The present invention compares with prior art, contain multiple oxidation inhibitor in the prescription, each component ratio optimization is reasonable, can keep premium propertiess such as good thermostability and the transparency, initial coloring, weather resisteant, ageing resistance, printing, durable nondiscoloration compliance with environmental protection requirements again to the PVC goods, characteristics such as excellent performance, production cost are low are suitable for and apply.

Embodiment

Be further described below in conjunction with the present invention of embodiment.

Barium-zinc liquid stabilizer adopts the feedstock production of following weight ratio to form among the present invention:

Isocaprylic acid: 20%～35%;

Oleic acid: 10%～15.5%;

Barium monohydrate: 8.5%～12.8%;

Zinc oxide: 1%～5%;

Diethylene Glycol butyl ether: 5%～10.5%;

Comprehensive oxidation inhibitor: 1%～3%;

Metal passivator: 1%～3%;

Beta-diketon: 1.5%～2.5%;

Anti-precipitation agent: 5%～10.5%;

DOP：20%～35%，

Wherein, described comprehensive antioxidant be AO20 antioxidant, AO30 antioxidant, AO40 antioxidant, AO50 antioxidant, 168 antioxidants by etc. weight ratio mix.

Described metal passivator is N, N'-two salicylidene propylene diamine.

After above-mentioned raw materials is ready to, be prepared as follows: (1) is put into the Diethylene Glycol butyl ether of isocaprylic acid, oleic acid, barium monohydrate, zinc oxide and half amount in the reactor successively again, stirring is warming up to 80～90 ℃, and is incubated to complete reaction with this temperature, and solution becomes is transparent; (2) be warming up to 100～110 ℃, carry out vacuum hydro-extraction; (3) add comprehensive antioxidant, metal passivator, β more successively--diketone, anti-precipitation agent, DOP and remaining Diethylene Glycol butyl ether, stir under 115～125 ℃ of temperature and got product in 0.5～2 hour.

In the PVC calendered film, add the barium-zinc liquid stabilizer 1～2.5wt% for preparing as stated above, compare with the present barium-zinc liquid stabilizer of selling on the market of in the PVC calendered film, adding isodose, after tested, adopt its thermostability of barium-zinc liquid stabilizer, weather resisteant, ageing resistance among the present invention obviously to optimize.
