Abstract

The invention discloses a flame-retardant foam material, which is characterized by comprising the following raw materials by weight: 100 parts of SG-3 polyvinyl chloride, 4-5 parts of aluminum hydroxide, 1-2 parts of zinc borate, 4-5 parts of azodicarbonamide, 1-2 parts of sodium bicarbonate, 12-14 parts of talcum powder, 2-3 parts of polyethylene oxide, 2.3-2.8 parts of polyoxyethylene octylphenol ether, 0.9-1.1 parts of an antioxidant 565, 4-5 parts of tributyl citrate, 3-4 parts of polyisobutylene, 2-3 parts of zinc oxide, 1-2 parts of stearic acid and 6-8 parts of a modified filler. The fire retardants of aluminum hydroxide and zinc borate added in the invention endow the foam material with very rare excellent flame effect while maintaining the advantages of insulation, light weight and low water absorption rate.

Description

A kind of flame-retardant foam material

Technical field

The present invention relates to a kind of foam material, particularly a kind of flame-retardant foam material.

Background technology

The purposes of foam material is very extensive, because it has high strength, light, splendid insulation heat-insulating property and the high energy ability that absorbs of quality, can be used as the wrapping material of various instrument, valuables, precision instrument, vegetable and fruit and fishery products etc.; And because its have that thermal conductivity is low, water-absorbent is little, electrical insulating property is good, sound insulation, protection against the tide and the good characteristic such as moulding process is simple, and be widely used in the aspects such as lagging material that industry was fished for and refrigerated in the roadbed laying of road and bridge and building construction and fishery.Wherein, as a kind of good material of construction, foamed polystyrene resin is mainly used in roofing and the body of wall of buildings, and it has very good energy-saving effect as external heat insulating composite wall; And be applicable to house, factory, flat and pitch roofing as heat insulation house surface, can play the effects such as sound insulation, dash steam, sealing and heat insulating.As lagging material for building, several performance index of overriding concern are low thermal conductivities, high fire retardancy, preferably adhesiveproperties and preferably self intensity.

Flame-retardant foam material, because it has light weight, the performance such as fire-retardant, is widely used in the various fp occasions that need.But existing flame-retardant foam material, its flame retardant properties is not still too desirable, cannot meet the higher occasion of some fire protection requirement, is still subject in the use some limitations.

Summary of the invention

The object of this invention is to provide a kind of flame-retardant foam material with excellent fire-retardancy.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A flame-retardant foam material, is made by the raw material of following weight part: SG-3 polyvinyl chloride 100, aluminium hydroxide 4-5, zinc borate 1-2, Cellmic C 121 4-5, sodium bicarbonate 1-2, talcum powder 12-14, oxidic polyethylene 2-3, polyoxyethylene octylphenol ether 2.3-2.8, oxidation inhibitor 565 0.9-1.1, tributyl citrate 4-5, polyisobutene 3-4, zinc oxide 2-3, stearic acid 1-2, modified filler 6-8;

Described modified filler is prepared by the following method: the raw material that takes following weight part: attapulgite 90-100, diatomite 20-24, stalk ashes 50-55, Sodium dodecylbenzene sulfonate 2-3, bicarbonate of ammonia 2-3, mica 3-4,2-amino-2-methyl isophthalic acid-propyl alcohol 3-4, Tremoliteor Tremoliteasbestos 5-6, magnesium sulfate 2-3, nano silicon 1-2, epoxy soybean oil 2-3, Starso 2-3, Sodium Selenite 4-5; Preparation method puts into calcining furnace by attapulgite, diatomite, mica, Tremoliteor Tremoliteasbestos, at 530-570 ℃, calcine 4-5 hour, take out, mix with stalk ashes, bicarbonate of ammonia, be ground to and obtain 300-400 order powder, then, add again nano silicon, Starso, 2-amino-2-methyl isophthalic acid-propyl alcohol, epoxy soybean oil to mix, continue to grind 30-45 minute, to fully disperseing, then add other remaining component, continue to grind after 30-45 minute, under 1500-1800 rev/min, stir 15-30 minute, obtain modified filler.

Flame-retardant foam material of the present invention, is prepared from by following concrete steps:

(1) by other each mixing of materials except modified filler, Cellmic C 121, be warming up to 100-120 ℃, mixing 8-12 minute;

(2) material mixing is added modified filler, Cellmic C 121 carry out the mixing 6-10 minute of secondary at 90-100 ℃;

(3) material secondary being mixed hacks, slice, sends in molding device and carries out premolding, and forming pressure is 4-6MPa, and 15-20 takes out after second;

(4) sheet stock is added in the mould of preheating, on vulcanizing press, at 140-160 ℃ of temperature, is forced into 6-7MPa, pressurize 6-12min, removes foam, is cooled to normal temperature and get final product.

The present invention adds the fire retardants such as aluminium hydroxide, zinc borate, makes foam material have very rare excellent flame retardant effect, and kept insulation simultaneously, the advantage such as light weight, water-intake rate are low.

Specific embodiments

Below by specific examples, the present invention is described in detail.

A flame-retardant foam material, by following weight part (kilogram) raw material make: SG-3 polyvinyl chloride 100, aluminium hydroxide 4, zinc borate 1, Cellmic C 121 4, sodium bicarbonate 1, talcum powder 12, oxidic polyethylene 2, polyoxyethylene octylphenol ether 2.3, oxidation inhibitor 565 0.9, tributyl citrate 4, polyisobutene 3, zinc oxide 2, stearic acid 1, modified filler 6;

Described modified filler is prepared by the following method: take following weight part (kilogram) raw material: attapulgite 90, diatomite 20, stalk ashes 50, Sodium dodecylbenzene sulfonate 2, bicarbonate of ammonia 2, mica 3,2-amino-2-methyl isophthalic acid-propyl alcohol 3, Tremoliteor Tremoliteasbestos 5, magnesium sulfate 2, nano silicon 1, epoxy soybean oil 2, Starso 2, Sodium Selenite 4; Preparation method puts into calcining furnace by attapulgite, diatomite, mica, Tremoliteor Tremoliteasbestos, at 530-570 ℃, calcine 4-5 hour, take out, mix with stalk ashes, bicarbonate of ammonia, be ground to and obtain 300-400 order powder, then, add again nano silicon, Starso, 2-amino-2-methyl isophthalic acid-propyl alcohol, epoxy soybean oil to mix, continue to grind 30-45 minute, to fully disperseing, then add other remaining component, continue to grind after 30-45 minute, under 1500-1800 rev/min, stir 15-30 minute, obtain modified filler.

Each functional parameter of the flame-retardant foam material of gained is as follows: hardness (Shao Shi C, o) 38.5, elongation at break (%) 186, tensile strength (MPa) 1.55, impact rebound degree (%) 42.0, compressive set (%) 34.0.
