Embodiment 1

[0013] Embodiment 1 provides a kind of ACR modification system plastics, it comprises the PVC of percentage greater than 80.5%, the ACR impact modifier of 5.0%-8.0%, the ACR processing agent of 0-1.0%, the ACR processing agent of 4.0%-4.5% Composite lead salt, 0.5-0.8 calcium stearate.

[0014] Simultaneously, a kind of plastics that is used to produce ACR modified system comprises the following steps:

[0015] (1) The mass percentage is greater than 80.5% PVC, 5.0%-8.0% ACR impact modifier, 0-1.0% ACR processing agent, 4.0%-4.5% composite lead salt, 0.5-0.8 hard Calcium fatty acid solvent mixed evenly;

[0016] (2) Process the mixed solution into powder through a series of steps of heating, filtering and crystallization;

[0017] (3) Inject the powder into a plunger or screw driven by an injection cylinder for injection molding;

[0018] (4) The material after injection molding is integrally pressed and formed in the prefabricated mold.

[0019] It is important to note th...

Abstract

The invention relates to an organic polymer composite material, specifically relates to an ACR modified system plastic which comprises more than 80.5% of PVC, 5.0%-8.0% of ACR impact modifier, 0-1.0% of ACR processing agent, 4.0%-4.5% of composite lead salt, 0.5%-0.8% of calcium stearate, 0.5%-1.5% of lubricant, 4.0%-6.0% of light calcium carbonate and 4.0%-6.0% of rutile. The low-temperature impact resistance of the ACR modified system plastic is enhanced, and the utilization rate of the plastic can be increased further.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to an ACR modified system plastic. Background technique [0002] ACR (Acrylic copolymer) is an acrylic copolymer with a core-shell structure, and it is a PVC impact modifier with excellent comprehensive performance. Generally, the additives used to improve the toughness of plastics are called impact modifiers, and the additives used to improve the processing performance are called processing modifiers. ACR is a plastic additive with dual functions of impact resistance modification and processing modification. Because of its core / shell structure, its PVC products have excellent impact resistance, low temperature toughness, compatibility with PVC, weather resistance, Stability, processability, and moderate performance-to-price ratio, can significantly improve PVC melt fluidity, thermal deformation, promote plasticization, and make the product surface smooth and be...
