Description
Technical field
The invention discloses a kind of foamed heat insulating pearl cottons, belong to building material technical field.
Background technology
Pearl cotton is also known as EPE, is non-crosslinked hole-closing structure, is a kind of packaging material of novel environment friendly.It is gathered by low-density
Ethylene fat generates countless independent air bubbles through physical blowing and constitutes.Overcome common foamed glue it is frangible, deformation, it is restorative difference lack
Point.It is many excellent that moisture-proof with water proof, shockproof, sound insulation protects that plasticity is good, toughness is strong, reconstituted circularly, environmental protection, crashworthiness power are strong etc.
Point also has good chemical resistance.It is the ideal substitute of conventional packaging material.
Pearl cotton is widely used in electronic apparatus, instrument and meter, computer, sound equipment, medical instrument, industry control cabinet, hardware lamp
The high-grade frangible gift wrap such as decorations, craftwork, glass, ceramics, household electrical appliances, spraying, furniture family property, drinks and resin, hardware,
The packaging of the multiple products such as toy, melon and fruit, the inner packing of leather shoes, daily necessities.After colored antistatic agent and fire retardant is added, effectively
Prevent electrostatic and combustion.
The adhesive article of EPE and various fabrics is various vehicles and the good interior finish material in room.EPE pearl wool and aluminium
The composite article of foil or metallized film has excellent anti-UV and IR ability, is some chemical industry equipment freezers and to camp
Equipment automobile sun-shading must articles for use.Its tubing is largely used to air-conditioning, perambulator, toy for children, family property, the industries such as hot-water heating ventilation.
It is extraordinary due to having the advantages that, it is not only free from environmental pollution, and can repetitiousness recycle, therefore EPE pearl wool foam
Material is a kind of novel, southern exposure unabated material forever.Application, EPE pearl wool are continually developed with the propulsion and product of time
Expanded material will be applied even more extensively in terms of packing and filling materials.
Pearl cotton is high-foaming formed product, light-weight, has certain robustness flexibility and buffering fine, thermal conductivity is very
Low thermal insulation is very excellent.The foam material of independent air bubble is the waterproof material almost without water imbibition.High-foaming and outstanding water proofing property, make
It has very strong buoyancy effects.Not by various drug corrosivity rotproofness materials.Not by various weather influences, against weather
Superior, the foam material of independent air bubble has good soundproof vibration-isolating effect.But there is also fire-retardant for foaming pearl cotton traditional at present
Performance and the bad problem of heat-insulating property, therefore also need to study it.
Invention content
The present invention solves the technical problem of：It is bad for traditional foaming pearl cotton flame retardant property and heat-insulating property
Problem provides a kind of foamed heat insulating pearl cotton.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of foamed heat insulating pearl cotton, is made of the raw material of following parts by weight：60~80 parts of high density polyethylene (HDPE)s, 10~20

The preparation process of the foamed heat insulating pearl cotton is：
（1）It is formed by raw material and weighs each component raw material；
（2）By high density polyethylene (HDPE), phenol-formaldehyde resin modified, polyacrylic acid zinc resin, sodium bicarbonate, foaming agent, crosslinking agent, silane
Coupling agent pre-processes maize cob meal, dimethyl silicone polymer, and zinc flake and phosphatide are kneaded, and extrusion molding is heated to get hair
Bubble heat preservation pearl cotton.
The preparation process of the phenol-formaldehyde resin modified is：It counts in parts by weight, by 30~40 parts of glyoxal solutions, 10~20
Part sodium hydroxide solution, 30~40 parts of hydroquinone constant temperature are stirred to react, and are cooled down, and 0.2~0.3 times of glyoxal solution volume is added
Ethylene urea be stirred to react, cool down, the Silane coupling reagent KH-570 that 0.1~0.2 times of glyoxal solution volume is added is stirred to react,
Cooling is to get alkalescent phenol resin.
The foaming agent is azodicarbonamide, dinitrosopentamethylene tetramine or 4, in 4'- oxobenzenesulfonyl hydrazide
Any one.
The crosslinking agent is that the preparation process of pretreatment maize cob meal is：Corncob dry, pulverize, cross the sieve of 100 mesh,
Maize cob meal is obtained, is counted in parts by weight, by 10~20 parts of maize cob meals, 20~30 portions of sucrose, 10~20 portions of linseed oil mix, with
After be filled with high-pressure carbon dioxide, it is cooling, obtain pretreatment maize cob meal.
The silane coupling agent is any one in silane resin acceptor kh-550 or silane coupling agent KH-560.

The beneficial effects of the invention are as follows：
（1）The present invention pre-processes maize cob meal by addition, and in preparation process, maize cob meal passes through mixed with sucrose, linseed oil
It closing, then through high temperature and high pressure carbon dioxide treatment so that carbon dioxide can penetrate into maize cob meal, then pass through freezing,
So that high-pressure carbon dioxide is stored in maize cob meal, in use, sodium bicarbonate is thermally decomposed, and generates water, corncob
Sucrose in powder is dissolved in water, while releasing carbon dioxide, on the one hand, titanium dioxide Carbon diffusion so that corncob powder
Product increases, and hole increases, and on the other hand, the release of carbon dioxide can assist system to foam, and further promote the porosity of system,
Meanwhile the diffusion of gas makes the linseed oil in maize cob meal discharge to its surface, and it is again dry solid on maize cob meal surface
Change, realize the effect of plug-hole so that the rate of closed hole in system is further promoted, to further promote the guarantor of system
Warm nature energy；
（2）The present invention is by adding dimethyl silicone polymer and zinc flake, under the conditions of high temperature fire, dimethyl silicone polymer
It is thermally decomposed, and generates free radical, the free radical of generation is combined with zinc flake, forms organic cross-linked structure, is effectively obstructed
The invasion of heat and oxygen plays the flame retardant effect of fire early period, with the raising of temperature, is formed in organic cross-linked structure
Organic matter carbonizes, and forms foamed char, plays the role of heat-insulated and barrier air, meanwhile, fuel gas can be prevented to enter
In phase of burning, the progress of combustion reaction is interrupted, to further promote the flame retardant property of product.
