Abstract
The invention discloses a multi-component polystyrene (PS) physical foaming agent and a production method of PS foamed products. The multi-component PS physical foaming agent is prepared from CO2 and an auxiliary agent of which weight is 12.5 to 50% of weight of the CO2, wherein the auxiliary agent comprises: by weight, 50% of a CO2 foam stabilizer, 10% of a CO2 absorbent and 40% of an entrainer. The CO2 foam stabilizer comprises: by weight, 99.5% of water and 0.5% of sodium laurate. The CO2 absorbent comprises: by weight, 50% of polyethylene glycol dimetyl ether and 50% of polypropylene carbonate. The entrainer is an ethanol solution with purity above 99%. The production method comprises pouring 7 to 11 wt% of the multi-component PS physical foaming agent into 89 to 93 wt% of PS materials under the pressure of 20 to 30 Mpa, and through a foaming screw, supercharging, blending, cooling and conveying to a forming machine head to form foamed products. The foamed products produced by the production method adopting CO2 as a foaming agent have the advantages of energy saving and environmentally friendly characteristics, high anti-compression performances, greatly low water absorption and moisture-permeable coefficients, and reliably dimensional stability.
Description
Technical field
The present invention relates to a kind of many components PS pneumatogen and use this whipping agent to produce the method for PS foaming product.
Background technology
At present; Domestic plastics physical blowing enterprise mostly adopts HCFC22 or 142B to make whipping agent, because it contains fluorine chlorine molecule, atmospheric environment and ozonosphere is had certain destruction; Arrange according to " Montreal "; Developing country will gradually reduce and freeze its output before the year two thousand thirty, at the use that has been under an embargo of this product of developed country, CO
2Foaming technique will become the desirable substitute products of HCFC, CO
2Boiling point-78.5 ℃ is gaseous state at normal temperatures, CO
2Nontoxic to environment, do not fire not quick-fried, etching apparatus not, environmental protection, CO
2As whipping agent foam PS goods, be difficult to form the goods of high foamability more than 20 times separately, because CO
2Perviousness more intense, in PS, be easy to separately ooze out, can't form bubble.At present, production CO is arranged both at home and abroad
2Foaming product, but all be to mix use with the fluorochlorohydrocarbon whipping agent or mix use with butane, propane, dme, still not environmental protection, it is dangerous perhaps to catch fire easily.
Summary of the invention
The method that the purpose of this invention is to provide a kind of many components PS pneumatogen and produce the PS foaming product solves normal and stable production with CO
2Production difficult problem for the foaming product of whipping agent does not contain the fluorochlorohydrocarbon whipping agent or does not contain inflammable blowing agents such as butane, propane, dme, is prone to produce, nontoxic, nonflammable.
The objective of the invention is to realize as follows: this many component PS pneumatogen is by CO
2Be CO by quality
2The auxiliary agent proportioning of 12.5%-50% after form, wherein auxiliary agent is by 50% CO
2Suds-stabilizing agent, 10% CO
2Absorption agent, 40% entrainer are formed by quality; CO
2Suds-stabilizing agent is that 99.5% water and 0.5% sodium laurate are formed CO by quality
2Absorption agent is that 50% poly glycol dimethyl ether and 50% the propylene carbonate that gathers are formed by quality, and entrainer is the ethanol of purity more than 99%.If CO
2Separately as whipping agent foam PS goods, because CO
2Perviousness more intense, in PS, be easy to separately ooze out, can't form bubble, we adopt other solvent and CO
2Blend adds CO
2Absorption agent can effectively increase CO
2With the phasic property of auxiliary agent, promote CO
2Solubleness in the PS melt adds CO
2Suds-stabilizing agent can effectively reduce CO
2Rate of permeation in the PS goods reaches a kind of eutectic system close with air, adds CO
2Entrainer can effectively reduce CO
2Absorption agent, CO
2The boiling point of suds-stabilizing agent is easy to outlet and expands, and is easy to foaming, thereby can produces even and resilient foaming product.
The method of utilizing said PS whipping agent to produce the PS foaming product is: by quality the PS whipping agent of 7%-11% is injected the PS material of 89%-93% with the pressure of 20Mpa-30Mpa, this mixture through the supercharging of foaming screw rod, blend, cool off, be transported to former and be shaped to foaming product.
The present invention is with CO
2For the foaming product of whipping agent production is that environmental protection is energy-conservation again; Goods are widely used in numerous areas such as building energy conservation heat insulation, the control of ground frost heave, refrigerating plant insulation with superior high compressive property, extremely low water-intake rate and moisture permeable coefficient and dimensional stability reliably.
Embodiment
The PS whipping agent is by CO
2Be CO by quality
2The auxiliary agent proportioning of 12.5%-50% after form, wherein auxiliary agent is by 50% CO
2Suds-stabilizing agent, 10% CO
2Absorption agent, 40% entrainer are formed by quality; CO
2Suds-stabilizing agent is that 99.5% water and 0.5% sodium laurate are formed CO by quality
2Absorption agent is that 50% poly glycol dimethyl ether and 50% the propylene carbonate that gathers are formed by quality, and entrainer is the ethanol of purity more than 99%.The PS whipping agent of 7%-11% is injected the PS material of 89%-93% by quality with the pressure of 20Mpa-30Mpa; This mixture through foaming screw rod supercharging, blend, cool off, be transported to former; Behind head, the material high pressure discharges rapid expansion and forms foaming product.
