Embodiment 1

[0029] Raw material weight ratio:

[0030]

[0031] First, add the above two glass powders and silane coupling agent into a high-speed mixer, mix at 60°C for 20 minutes, and then discharge, and then dry to obtain surface-treated glass powder. Then, the ethylene-vinyl acetate copolymer was poured into a two-roll open mill, and the temperature was kept at 110 °C for 2 minutes, so that the organic polymer could wrap the front roller; then glass frit 1 and low softening point were added respectively. The glass powder is mixed, and the general mixing time is 12 minutes. Finally, the blend was put into a flat vulcanizer, kept at 150°C and preheated for 5 minutes, then hot pressed at 10 MPa for 10 minutes, and then cold pressed at 5 MPa for 5 minutes to produce the sheet. The performance test results are shown in Table 1.

Embodiment 2

[0033] Raw material weight ratio:

[0034]

[0035] The preparation method is the same as that in Example 1, and the performance test results are shown in Table 1.

Abstract

The invention discloses an anti-dripping ceramic polyolefin composite material and a preparation method thereof. The anti-dripping ceramic polyolefin composite material meets all requirements for mechanical performance in the fire protection field at the normal temperature; when being burnt, the composite materials is not caused to drip so that fire expansion can be prevented. The anti-dripping ceramic polyolefin composite material is prepared from the following raw materials in parts by weight: 30-60 parts of polyolefin, 20-40 parts of high-softening point glass powder, 20-40 parts of low-softening point glass powder, 0-15 parts of organic montmorillonite, 0.5-2.5 parts of coupling agent and 0-3 parts of compatilizer.

Description

technical field [0001] The invention relates to a polyolefin composite material and a preparation method thereof, in particular to a drip-proof ceramicized polyolefin composite material and a preparation method thereof. Background technique [0002] After entering the 21st century, with the improvement of people's living standards and fire safety awareness, as well as the continuous increase of high-rise buildings, hotels, supermarkets, hospitals, stations, airports, subways, and tunnels, the importance of fire safety has become prominent. This issue has attracted great attention. This requires us to develop a cheap, simple and practical refractory material. And the anti-drip ceramified polymer composites in this paper just meet this requirement. It can be applied in: household appliances, transportation, and power transmission. Typical functions of this material: ①When a fire occurs, some burning polymer composites will not drip, and the flame will spread to other places...
