Description

Preparation method of VOC modified filler mesoporous magnesium oxide for automotive interiors and PC composite material
Technical Field
The invention relates to a preparation method of VOC modified filler mesoporous magnesium oxide for automotive interiors and a PC composite material, belonging to the technical field of automotive interiors.
Background
The national control of automobile VOCs is becoming more stringent, and the demand for low odor plastic materials is increasing within the industry. The odor level requirements have been included in one of the primary indicators in many automotive fitting enterprises. At present, automobile interiors are mainly made of materials such as Polycarbonate (PC), PVC and the like, strong pungent smell can be emitted in the use process, and when volatilized gas reaches a certain concentration in an automobile, people in the automobile feel uncomfortable and bad influence on the health is generated.
In the specific application fields of automobiles and the like, the VOC performance requirements of the materials are higher and higher, the requirements of common PC materials and the like cannot be met, and the application of the PC materials and the like in the specific fields is limited to a certain extent. Therefore, in order to solve the odor problem of emitting VOC around the plastic material for automotive interior, the odor absorbing material such as zeolite and molecular sieve is mainly added into the plastic material to adsorb volatile gases of small molecules in a physical or chemical manner, but how to achieve the low VOC odor effect is not ideal in practical application. This requires that the adsorption be made of what material is used as an additive to ensure the performance of achieving low VOC odors.
The magnesium oxide particles as the adsorption material have better physical and chemical properties, which are incomparable with other materials, but the magnesium oxide prepared by the conventional method still has the problem of unsatisfactory adsorption performance, such as weak adsorption capacity, and is unfavorable for effectively adsorbing VOC gas. Magnesium hydroxide is usually prepared in the preparation of magnesium oxide materials as in the prior art, and then mesoporous magnesium oxide is formed by calcination. The mesoporous magnesia prepared by the method has poor pore-forming property and weak adsorption capability to VOC, and also has a soft template method which takes amphiphilic organic molecules or block copolymers as templates, but because magnesium ions have low hydrolysis speed under alkaline conditions and effective acting force is difficult to form between the magnesium ions and the templates, the mesoporous magnesia is not easy to prepare.

The reaction principle in the above-mentioned mesoporous magnesium oxide production process can be explained by the following manner (hereinafter, using (NH) 4 ) 2 Mg(SO 4 ) 2 To represent magnesium ammonium sulphate):
(NH 4 ) 2 Mg(SO 4 ) 2 +3NH 4 HCO 3 →NH 4 MgOHCO 3 +2(NH 4 ) 2 SO 4 +2CO 2 +H 2 O
NH 4 MgOHCO 3 →MgO+NH 3 +H 2 O+CO 2
