Abstract

The invention discloses an environment-friendly self-aromatic polypropylene material and a preparation process thereof. The preparation process comprises the following steps: adding a liquid state edible aromatic by taking HMSPP (High Melt Strength Polypropylene) as a main raw material; and preparing through a carbon dioxide supercritical method (the reaction temperature is 90-160 DEG C, the reaction pressure is 8-22MPa and the reaction time is 2-6 hours). The invention changes the conventional process of aromatic plastic and the weaknesses that the plastic contains toxin. The material prepared by the invention has the characteristics of environment friendliness, automatic diffusion of aromatic odor and the like. The percentage of close area is greater than 90%, the foaming ratio is 3-40 times, the abscess size is 50-270 mu m, and the weight loss ratio half a year of the aromatic in a standard environment is not greater than 20%. The material is particularly suitable for being applied to the fields such as automobile decoration, furniture decoration and toys for children. In addition, the preparation process disclosed by the invention is easy to control and suitable for continuous production.

Description

A kind of environmental protection is from fragrant polypropylene material and preparation technology thereof
Technical field
The invention belongs to macromolecular material in Materials science and the field of process of preparing thereof, be specifically related to a kind of environmental protection from fragrant polypropylene material and preparation technology thereof.
Background technology
Along with expanding economy, people increase day by day to the requirement of the aspects such as environmental protection, safety, comfort level, and ecotope and value of life are also more paid close attention to.The existing fragrant plastics overwhelming majority makes for situ aggregation method, due to the restriction of drawing materials, contains formaldehyde, the hazardous and noxious substances such as stupid in material.Along with the pay attention to day by day of people to health, environment and ecological protection, environmental protection standard and the environmental standard also increasingly stringent of people to material therefor.Material of the present invention has environmental protection, lightweight, comfortableization, personalization, callable feature.For social development, improve people's living environment, application CO 2 supercritical method is produced and is very important from fragrant polyacrylic exploitation.
Summary of the invention
Mechanism of the present invention is shown in Figure of description.
Fragrant polypropylene material prepared by the present invention can meet its application in fields such as automobile decoration, furniture decoration, toys for children, and component concentration HMSPP of the present invention is 80-90wt%, and liquid edible type perfume compound is 0-20wt%.
The CO 2 supercritical legal system of the present invention's application is standby as follows from the concrete technology of fragrant polypropylene material: starting material are put in autoclave, under CO 2 supercritical state, through the temperature of 90-160 ℃, the reaction times of the pressure of 8-22MPa and 2-6 hour prepares and obtains.
Prepared by the present invention is greater than 90% from fragrant polypropylene material rate of closed hole, and expansion ratio 3-40 times, abscess-size 50-270 μ m, under standard environment, perfume compound rate of weight loss half a year is not more than 20%.
Each embodiment performance clicks standard testing, and concrete examination criteria is as follows:
