Abstract

The invention discloses a kind of certainly fragrant polypropylene material of environmental protection and its preparation processes.The present invention uses novel preparation process, i.e., using HMSPP as primary raw material, adds liquid edible-type aromatic, pass through CO 2 supercritical method（90 160 DEG C of reaction temperature, 8 22MPa of reaction pressure, 26 hours reaction time）It is prepared.The present invention changes the traditional handicraft of fragrant plastics and itself contains the weakness of toxin.Material produced by the present invention has the characteristics that environmental protection, distributes aromatic odor automatically, and rate of closed hole is more than 90%, and 3 40 times of expansion ratio, 50 270 μm of abscess-size, aromatic half a year weight-loss ratio is not more than 20% under standard environment；It is applied especially suitable for fields such as automobile decoration, home decoration, toys for children.Moreover, it relates to preparation process it is easily controllable, and be suitable for continuous production.

Description

It is a kind of environmentally friendly from fragrant polypropylene material and its preparation process
Technical field
The invention belongs to the fields of high molecular material and its process of preparing in material science, and in particular to Yi Zhonghuan It protects from fragrant polypropylene material and its preparation process.
Background technology
With the development of economy, requirement of the people to environmental protection, safety, comfort level etc. is increasingly increased, to ecological environment It is also more paid close attention to value of life.The existing fragrance plastics overwhelming majority is made for situ aggregation method, due to the limitation of materials, material Contain the poisonous and harmful substances such as formaldehyde, stupid in material.As people are to the pay attention to day by day of health, environment and ecological protection, people couple The environmental protection standard and environmental standard of material therefor are also increasingly strict.Material of the present invention has environmental protection, lightweight, comfortableization, individual character Change, recyclable feature.For the development of society, improve people’s lives environment, certainly using the production of CO 2 supercritical method The polyacrylic exploitation of fragrance is very important.
Invention content
Mechanism of the present invention is shown in Figure of description.
Fragrant polypropylene material prepared by the present invention disclosure satisfy that it in necks such as automobile decoration, furniture decoration, toys for children The application in domain, constituent content HMSPP of the invention are 80-90wt%, and liquid edible type aromatic is 0-20wt%.
The concrete technology that the CO 2 supercritical method that the present invention applies prepares certainly fragrant polypropylene material is as follows：By former material Material is put in autoclave, under CO 2 supercritical state, through 90-160 DEG C of temperature, the pressure and 2-6 of 8-22MPa The reaction time of hour is prepared.
Certainly fragrant polypropylene material rate of closed hole prepared by the present invention is more than 90%, 3-40 times of expansion ratio, abscess-size 50- 270 μm, aromatic half a year weight-loss ratio is not more than 20% under standard environment.
Each embodiment performance clicks standard testing, and specific examination criteria is as follows：
Simply supported beam notch impact strength ISO179
Tensile strength ISO527
Bending strength ISO178
Aromatic Retention（Ag）Self-defined standard
Ag=（m2-m1）/m1*100
