Problems solved by technology

[0006] In the prior art, modified polypropylene materials are mostly used to make automotive interior materials. Generally, talcum powder, calcium carbonate or mica powder need to be added as materials to enhance and reduce the shrinkage of the material; however, these powder materials The addition of PP will cause adverse reactions with polypropylene resin and its additives during processing, causing the VOC of the final material to exceed the standard, the odor will increase, and the odor requirements of automotive interior materials will not be met.

preparation example Construction

[0052] In a second aspect, the present invention provides a method for preparing plastic additives, comprising the following steps: weighing the above-mentioned raw materials in parts by weight; adding in turn the pulverized inorganic materials, active monomers, free radical initiators and optional catalysts and stirring 1. Heating and keeping warm to pre-react each raw material; the pre-reacted mixture is vacuum baked and then cooled to obtain the plastic additive.

[0053] In a further preferred solution of the present invention, the inorganic material is pulverized to an average particle size of less than 5 μm.

[0054] Preferably, the stirring is carried out in a stirrer, the stirring speed is 800-1000r / min, the stirring time is 5-10min, the temperature of the heat preservation is 150-180°C, and the heat preservation time is 30-60min.

[0055] In the present invention, the stirring speed is typical but not limited to: 800r / min, 820r / min, 840r / min, 860r / min, 880r / min, 900r / ...

Embodiment 1

[0065] A plastic additive comprises the following raw materials in parts by weight: 1000 parts of talcum powder, 1 part of vinyl acetate and 1 part of benzoyl peroxide.

Embodiment 11

[0067] A preparation method of the plastic additive described in embodiment 1, comprises the following steps:

[0068] (1) pulverize untreated talcum powder in a jet mill, so that the average particle diameter of talcum powder is less than 5 μm;

[0069] (2) Add talcum powder, vinyl acetate, benzoyl peroxide successively in the high-speed mixer, and seal the mixing tank of the mixer;

[0070](3) Start the mixer, the stirring speed is 800r / min, stir for 5 minutes, start heating the mixing tank, heat up to 150°C, and keep warm for 30 minutes;

[0071] (4) Transfer the pre-reacted mixture in step (3) to a rotary vacuum oven, keep the temperature at 180°C, keep the vacuum at -0.08MPa, keep it for 1 hour, cool down, and discharge to obtain the described plastic additives.

Abstract

The invention relates to the technical field of novel materials and, particularly, provides a plastic additive and a preparation method and application thereof. The plastic additive is of core-shell structure which employs an inorganic material as a core and a polymer material as a shell. The surface of the plastic additive provided herein is all of polymer characteristic, and the plastic additive is well compatible with plastic, causes no side effects when added in plastic, never produces stinking or toxic smell, is highly environmentally friendly, and has odor grade up to the level 2.5 when at 80 DEG C.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a plastic additive, a preparation method and an application thereof. Background technique [0002] With the strengthening of people's awareness of environmental protection, the problem of air pollution in cars has attracted more and more attention. On October 14, 2011, the Ministry of Environmental Protection approved GB / T 27630-2011 "Guidelines for Evaluation of Air Quality in Passenger Cars" and issued it in 2012. It was officially implemented on March 1. GB / T 27630-2011 is suitable for evaluating the concentration of VOC (volatile organic compounds) in passenger cars, and specifies the concentration requirements of VOCs in the air in the car, such as benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, ethyl Aldehyde, acrolein concentration requirements. The GB / T27630-2011 standard will be enforced in 2017. Based on this, it is imperative to develop automotiv...
