Description
Technical field
The present invention relates to one kind to be packed for vapor-permeable type sound-proof foam plastics and its production method, belongs to bubble wrap box
Technical field.
Background technology
Foamed plastics is a kind of high polymer material formed by a large amount of gas micropore dispersions in solid plastic, has matter
The characteristics such as gently, heat-insulated, sound-absorbing, damping, and dielectric properties are better than matrix resin, have many uses；Almost various plastics can be made
Foamed plastics, foaming turn into a key areas in plastic processing.
Foamed plastics is integrally covered with countless interconnect or mutually disconnected micropore and the modeling that makes apparent density substantially reduce
Material, there is light, adiabatic, sound-absorbing, shockproof, moisture resistance, corrosion-resistant.Foamed plastics is using plastics as solvent and contained
The polymeric material of a large amount of bubbles, therefore could also say that the composite plastic using gas as filler.
In the market there is hardness height in the foamed plastics for electric equipment products packaging, flexibility is poor, matter is heavy, adiabatic effect
The defects of fruit is poor, air permeable effect is bad, anti-seismic performance is short of, anticorrosion effect is bad.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the deficiencies in the prior art, there is provided one kind is packed for vapor-permeable type sound-proof foam plastics
And its production method.
Technical scheme is as follows：One kind is packed for vapor-permeable type sound-proof foam plastics, it is characterized in that, including it is following heavy
The each component of amount part is prepared：PPG 40-60 parts, triacetin 15-26 parts, polyisobutene 3-8 parts, Hai Pao
Stone flour 10-25 parts, (β-methoxy ethoxy) the silane 10-15 of vinyl three parts, ethoxylated dodecyl alcohol 3-5 parts, coconut palm chaff
8-12 parts, initiator 15-35 parts, foaming agent 20-40 parts, dead acoustic barrier material 5-15 parts, crosslinking agent 1-5 parts.
The dead acoustic barrier material is barium sulfate, lead powder, iron powder, diatomaceous mixture.
In the dead acoustic barrier material, barium sulfate, lead powder, iron powder, diatomaceous weight ratio are 3:2:5:1.
The initiator is dibenzoyl peroxide.
The crosslinking agent is Methacrylamide.
A kind of production method for being packed for vapor-permeable type sound-proof foam plastics, it is characterized in that, plastics materials are heated to melting
In state, by strong agitation, large quantity of air or other gases are introduced into liquid plastic, produce micropore；Rise to micropore
Certain volume；Leftover materials are put into, continues to stir and heats 30-300 minutes；Then all materials are put into injection (mo(u)lding) machine,
Foaming agent decomposes in machine barrel, and when material leaves head, pressure drops to normal pressure, and it is i.e. expanded foamed to dissolve in gas, finally obtains this
Foamed product.
PPG（Abbreviation polyethers）It is by initiator（Compound containing active hydrogen group）With oxirane（EO）, ring
Ethylene Oxide（PO）, epoxy butane（BO）Deng being made in the presence of a catalyst through sudden reaction.Polyethers yield the maximum is with glycerine
（Glycerine）Make initiator and epoxides（Usually PO and EO is used in combination）, by the feed way for changing PO and EO（Mixing adds
Or separately add）, dosage ratio, the charging condition such as order, produce various general PPGs.
Triacetin is used as nitrocellulose, the plasticizer of cellulose acetate.Because volatility is big, often and low volatility
Plasticizer such as dioctyl phthalate, dibutyl sebacate etc. are used in combination.It also is used as solvent.Casting is also served as using ester as solidification
The curing accelerator of agent phenolic resin adhesive, increase the concentration and rise reaction temperature of triacetyl glycerine, then make change connection anti-
Speed is answered to accelerate.
Sepiolite is a kind of fibrous hydrous magnesium silicate, opaque also not have generally in the color such as white, light gray, pale yellow
Gloss.The shape that they have is as soil block, and some is into a strange cot shape or concretion forms.Under an electron microscope it can be seen that it
Be to be got together to line up sheet by countless filaments.Sepiolite have one it is strange the characteristics of, can be absorbed very when they run into water
More water are hardened so as to become softness once drying.
Compared with the foamed plastics of existing electrical package, the present invention has many excellent performances：It is light, intensity is high,
Absorbable impact loads property is good, heat-insulated, sound insulation value is good, ventilative, also can be in the field such as industry, agricultural, building, communications and transportation
Extensive use.
