Diatomite is the green filler of one of extensively research in recent years, generally formed by the dead later silicate remains of the unicellular algae being referred to as diatom, mainly be made up of unbodied SiO2, it has the performance of some uniquenesses, as: porousness, lower density, larger surface-area, relatively incompressibility and chemical stability, pH value is neutral, nontoxic, suspension property is good, absorption property is strong.Adopt diatomite modified conventional plastic materials, give its specified property and have some bibliographical informations.Patent CN201410344081.7 utilizes diatomite modified expanded graphite, improves the performance that polarity oils pollution components is disposed in expanded graphite absorption, realizes its effective removal to pollutent various in water body.Patent CN201510044217.7 then utilizes in-situ polymerization by diatomite and polyetherketone Material cladding, diatomaceous porous feature makes the polyetherketone of in-situ polymerization enter in diatomite duct, decrease stress concentration, solve diatomite and disperse uneven problem in high melt, significantly improve the mechanical property of matrix material.But adopt diatomite porous structure, in-situ modified conventional P E plastics, preparation be suitable for buffering package and the good matrix material of machine-shaping resistance toheat there is not been reported.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, there is by utilizing diatomite the features such as porous, resistance toheat be good, provide a kind of high density polyethylene(HDPE) for buffering package and diatomite composite material, this invention is by original position coextrusion process, polyethylene long-chain and diatomite hole generation physical/chemical are interacted, and make both fully merge by capillary effect, improve the shortcomings such as heat resisting temperature in high density polyethylene(HDPE)/diatomite composite material buffering forming process is low, easily aging, corrugation cohesive force is low, for amortizing packaging material design provides a kind of new approaches.
The quality proportioning that matrix material of the present invention adopts is: high density polyethylene(HDPE) 30%-40%, calcium carbonate 50%-60%, diatomite 3%-6%, softening agent and coupling agent 2%-4%.
Softening agent of the present invention can be the one in phthalate, phosphoric acid ester (as Tritolyl Phosphate, triphenylphosphate, diphenyl octyl phosphate), polyester (as: sebacic acid series, serial, the phthalic acid series of hexanodioic acid etc.), preferably adopts dioctyl phthalate (DOP).
Coupling agent of the present invention is silane coupling agent, and having can be preferably A174 silane coupling agent.
The invention provides the preparation method of a kind of above-specified high density polyethylene and diatomite composite material, concrete preparation process comprises:
(1) first diatomite is dried at 110-120 DEG C to moisture and reach 0.4%-0.8%;
(2) high density polyethylene(HDPE) be placed in high-speed mixer and add softening agent and the coupling agent of formula rate simultaneously, under 300-600r/min rotating speed, mixing 2-10min, make batch mixing A;
(3) calcium carbonate of step (1) dried diatomite and formula rate is mixed, make mixed material B;
(4) mixed with mixed material B by batch mixing A, banburying in Banbury mixer, banburying temperature is 130-160 DEG C, the time is 5-15min; Then begin to pratise in mill, temperature of beginning to pratise is 130-160 DEG C, the time is 5-15min; Finally roll in four-roll calender, rolling temperature is 130-150 DEG C, obtains sheet material after calendering.
Advantage of the present invention and beneficial effect:
1. the present invention is by rational formula rate, give full play to synergy, add high density polyethylene(HDPE) 30%-40% simultaneously, calcium carbonate 50%-60%, diatomite 3%-6% three mate, both the content of calcium carbonate had been reduced, reduce production cost, simultaneously, due to high density polyethylene(HDPE) and diatomaceous synergy, to make the material prepared can overcome low temperature resistant shock-absorbing capacity poor, and more aging shortcoming, effectively improves ductility, have higher shock strength, tensile strength, tear strength, light weight is soft, wear resistance good; In addition, matrix material of the present invention is prepared into amortizing packaging material and has that protection against the tide is not water funk, good toughness not frangibility, also have good shock-resistance, dustless pollution-free environmental protection can repeatedly recycling.
2. in the present invention's formula, add coupling agent and the softening agent of specific proportioning, and first coupling agent is mixed in advance with HDPE, and then coordinate with other raw material, effectively can improve high density polyethylene(HDPE) and calcium carbonate, diatomaceous dispersity, make the more even of fillers dispersed, effectively improve mechanical property and the interface performance of integral material; And softening agent add the plasticity that can increase material, improve surface luster and outward appearance, improve toughness and shock strength, improve extensibility and elongation at break, improve the bonding to various base-material, make the performance of material more stable.
