Embodiment 1

[0041] 27 parts by weight of tributyl (tetradecyl) phosphomethanesulfonate are packed into a 500L dissolution kettle, and then 18 parts by weight of methyl methacrylate-butadiene-styrene ternary graft copolymer impact modification is added. The plastic additive was heated to 100°C in an oil bath, and magnetically stirred for 10 hours to obtain a plastic additive mixture.

[0042] Tributyl (tetradecyl) phosphomethanesulfonate can adopt the product of N / A brand of Bailingwei Chemical Technology Co., Ltd.

[0043] According to the formula in Table 2, each material was premixed and swelled at 110°C. After cooling to 75°C, it was added to a two-stage extruder, plasticized at 150°C, extruded and granulated to obtain the product.

[0044] SEIKO DSC 6200 was used to test the melting point (Tm), glass transition temperature (Tg) and heat enthalpy (ΔH) of the obtained product, and the differences of the test results are shown in Table 1.

[0045] The obtained products were processed on...

Embodiment 2

[0048] Put 35 parts by weight of 1-butyl-3-methylimidazolium hexafluorophosphate into a 500L dissolution kettle, and then add 15 parts by weight of methyl methacrylate-butadiene-styrene ternary graft copolymer for impact modification The plastic additive was heated to 120° C. in an oil bath, and magnetically stirred for 6 hours to obtain a plastic additive mixture.

[0049]1-butyl-3-methylimidazolium hexafluorophosphate can be the product with the brand name 174501-64-5 of Bailingwei Chemical Technology Co., Ltd.

[0050] According to the formula in Table 2, each material was premixed and swelled at 120°C. After cooling to 80°C, it was added to a two-stage extruder, plasticized at 130°C, extruded and granulated to obtain the product.

[0051] Using the same method as in Example 1, the Tm, Tg and ΔH tests were carried out, and the differences of the test results are shown in Table 1.

[0052] The same method as in Example 1 was used to test the impact strength, and the impact ...

Embodiment 3

[0054] Put 52 parts by weight of trihexyl(tetradecyl)phosphorus tetrafluoroborate into a 500L dissolution kettle, then add 13 parts by weight of chlorinated polyethylene impact modifier, heat the oil bath to 160°C, and stir magnetically for 4 hours. Obtain plastic additive mixture.

[0055] Trihexyl (tetradecyl) phosphorus tetrafluoroborate can adopt the product of 374683-55-3 from Bailingwei Chemical Technology Co., Ltd.

[0056] According to the formula in Table 2, each material was premixed and swelled at 130°C. After cooling to 85°C, it was added to a two-stage extruder, plasticized at 160°C, extruded and granulated to obtain the product.

[0057] Using the same method as in Example 1, the Tm, Tg and ΔH tests were carried out, and the differences of the test results are shown in Table 1.

[0058] The same method as in Example 1 was used to test the impact strength, and the impact results are shown in Table 3.

Abstract

The invention discloses plastic additive mixed liquor and a preparation method and an application thereof. The plastic additive mixed liquor comprises the following components in parts by weight: 40-90 parts of plasticizer and 10-60 parts of impact modifier, wherein, the plasticizer is ionic liquid which contains cations and organic weak acid anions, and the impact modifier is rubber polymer. After the plastic additive mixed liquor of the invention is added, polyvinyl chloride thermoplastic resin has excellent plasticity, elasticity and impact property, and greatly expands applications of the polyvinyl chloride thermoplastic resin, thereby having the capability of being used for preparing calendered sheets, thermal forming sheets, blow molding products, injection molding products, extruded products and similar products.

Description

technical field [0001] The invention relates to a plastic additive and its preparation method and application. Background technique [0002] Thermoplastic resins require the addition of various additives to improve their processing and / or performance characteristics. Commonly used plastic additives include: heat stabilizers, antioxidants, lubricants, plasticizers, antistatic agents, impact modifiers, fillers, dyes and pigments, etc. [0003] During the preparation of thermoplastic resin blends and the manufacture of plastic parts, various additives are usually added to thermoplastic resins as separate powders, granules or liquid components. Since thermoplastic blend formulations often require the use of many materials with different physical properties, the preparation of the blends is expensive and complex. [0004] The development and research of a plastic additive composition that can not only reduce the cost, but also simplify the preparation process and meet the requi...
