Example Embodiment

[0046] Example 1

[0047] Paraffin wax 1 (melting point 47.1℃, phase change latent heat 240J / g) and a kind of hollow glass fiber are mixed uniformly in a mixer at a mass ratio of 80:20, and then put into a water bath at 70℃ for heating and stirring continuously, 4h After being taken out and cooled, the energy storage enhanced material ESF-1 was prepared. Combine PP (brand name PP HP500N, purchased from CNOOC and Shell Petrochemical Co., Ltd.), flame retardant (decabromodiphenylethane, antimony trioxide and basic magnesium sulfate whiskers in a mass ratio of 4:1:5 The mixed bromine / antimony flame retardant), PP-g-MAH and additives are mixed in a high-speed mixer for 4 minutes and then granulated by melt extrusion with a twin-screw extruder. ESF-1 is fed from the extruder through a side feed Join in the middle. The mass ratio of polymer support material PP, energy storage reinforced material ESF-1, flame retardant, PP-g-MAH and additives is 20:60: 15: 4: 1. The additives are 0.5...

Example Embodiment

[0048] Example 2

[0049] In this embodiment, paraffin wax 1 is replaced by paraffin wax 2 (melting point 27.5°C, phase change latent heat 190J / g), and the paraffin wax 2 and hollow fiber are mixed and processed at a mass ratio of 90:10, and the water bath temperature is 60°C to make energy storage Reinforced material ESF-2. The flame retardant in this embodiment is a bromine / antimony flame retardant mixed with decabromodiphenylethane, antimony trioxide and basic magnesium sulfate whiskers in a mass ratio of 4:1:10. The mass ratio of polymer support material PP, energy storage reinforced material ESF-2, flame retardant, PP-g-MAH and additives is 25:55:16:3.6:0.4.

[0050] The rest of the content of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Example Embodiment

[0051] Example 3

[0052] In this embodiment, the paraffin wax 1 and the hollow fiber are mixed and processed at a mass ratio of 70:30, and the temperature of the water bath is 65° C., to make the energy storage enhancement material ESF-3.

[0053] The mass ratio of polymer support material PBT, energy storage reinforcement material, flame retardant compound, PP-g-MAH and additives is 40: 30: 25: 4: 1. The flame retardant is a nitrogen and phosphorus compound flame retardant, the compatibilizer is glycidyl methacrylate, and the auxiliary agent includes 0.4% antioxidant, 0.4% lubricant and 0.2% Light stabilizer.

[0054] The rest of the content of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of high polymer materials, in particular to a reinforced flame-retardant heat insulation composite material. The reinforced flame-retardant heat insulation composite material consists of the following raw materials in percentage by weight: 10 to 40 percent of high polymer supporting material, 30 to 70 percent of energy storage reinforcing material, 10 to 40 percent of a flame retardant, 3 to 8 percent of a compatilizer and 0 to 2 percent of an assistant, wherein the high polymer supporting material is thermoplastic material; the energy storage reinforcing material is hollow fiber coated paraffin. The reinforced flame-retardant heat insulation composite material disclosed by the invention has better heat insulation and flame retardance effects, basically has no separation phenomenon, has higher intensity and can be used in the fields of buildings, automobiles and the like and the heat insulation effect is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a reinforced flame-retardant and thermal insulation composite material. Background technique [0002] The scarcity of energy has led to more and more attention to energy-saving materials, among which thermal insulation materials have become the focus of development in the fields of construction, automobiles and agriculture. [0003] Most of the thermal insulation materials on the market now achieve the thermal insulation effect by reducing the thermal conductivity, such as polyurethane, polystyrene foam, etc. In automobiles, the multi-layer structure of fiber felt and foam material is sometimes used to achieve the effect of enhanced thermal insulation. But this kind of insulation material can only reduce the rate of temperature change, and cannot keep the temperature constant. Phase change energy storage materials undergo a phase change near their phase change temperat...
