preparation example Construction

[0031] see figure 1 , the preparation method of polyolefin VOC improved filler that the present invention proposes, comprises the following steps:

[0032] S10, adding dioctadecyldimethylammonium bromide and methyldiethanolamine to water to form a solution.

[0033] In this step, the role of dioctadecyldimethylammonium bromide is a surfactant, which is attached to the prepared mesoporous TiO 2 / MgO improves the surface of the filler particles and modifies the surface so that the mesoporous TiO 2 / MgO improved packing is easy to adsorb VOC; methyldiethanolamine is used to provide an alkaline environment, and the present invention does not limit the ratio of the above-mentioned dioctadecyldimethylammonium bromide, methyldiethanolamine and water, preferably Specifically, the mass ratio of dioctadecyldimethylammonium bromide, methyldiethanolamine and water is (20-30): (10-16): (80-120). Within the above range, the obtained polyolefin VOC-improving filler has a uniform particle ...

Abstract

The invention discloses a polyolefin VOC (volatile organic compound) improved filler, a preparation method thereof and a polyolefin composite material, and relates to the technical field of polymer composite materials. The preparation method of the polyolefin VOC improved filler comprises the following steps of: S10, adding dioctadecyl dimethyl ammonium bromide and methyldiethanolamine into water to form a solution; S20, adding magnesium nitrate hexahydrate, cyclopentane and tetrabutyl titanate into the solution, and carrying out stirring reaction at 70-90 DEG C for 10-16 hours to obtain a mixed solution; S30, filtering the mixed solution to obtain a solid A, and washing and drying the solid A to obtain a solid B; and S40, calcining the solid B until the weight is not changed, cooling, grinding and sieving to obtain the mesoporous TiO2 / MgO improved filler, namely the polyolefin VOC improved filler. According to the preparation method of the polyolefin VOC improved filler, provided by the invention, the prepared polyolefin VOC improved filler is mesoporous TiO2 / MgO, VOC small molecules in polyolefin can be adsorbed, and the VOC content of the polyolefin is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a polyolefin VOC-improved filler, a preparation method thereof, and a polyolefin composite material. Background technique [0002] Polyolefin is an important thermoplastic material, which is widely used in automobiles, household appliances, mechanical parts, office supplies and communication equipment and other fields. Polyolefin has the advantages of light weight, non-toxic, odorless and good water absorption. With the vigorous promotion of the concept of environmental protection, people have higher and higher requirements for environmental protection of materials, and the performance of VOC (volatile organic compounds, volatile organic compounds) has been paid more and more attention. [0003] However, the existing polyolefin materials have high VOC content and cannot meet environmental protection requirements. Contents of the invention [0004] The main...
