Fat acid 1.0Phr, pigment 1.0-3.0Phr；By batch mixing, mill, slice, sulfur foam, it is cooled to
Type, the technological process of processing are prepared as the PE foaming ground cushion without Methanamide, instead of biography with OBSH foaming agent
The blowing agent AC of system, it is to avoid AC decomposes and produces harmful substance Methanamide, not only can expire in physical property
Its various use demands of foot, good springiness, coloring is easy, and Environmental Safety, nonpoisonous and tasteless, harmless,
Practical value is notable.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail:
Embodiment 1:
Use the environmental protection and safety type PE foaming ground cushion of OBSH foaming agent, including following raw material the most by weight:
Regeneration LDPE 50Phr, the ground calcium carbonate 20Phr of 1000 mesh, foaming agent 7.0Phr, zinc oxide 3.0Phr,
Stearic acid 1.0Phr, pigment 1.0-3.0Phr.
Wherein, regeneration LDPE is main material, selects the environmental protection after the recovered pelletize of high-pressure polyethylene film again
Raw high binder, the ground cushion material pliability of polyethylene from high pressure process foaming is good, flexible, low cost.
Foaming agent is 4,4 '-bis oxide benzene sulphur hydrazine OBSH foaming agent, for regulate foaming ground cushion hardness and
Density, its chemical molecular structural formula isDecomposition temperature is 150-160 DEG C,
Decomposition gas is nitrogen, and without Methanamide material, its thermal decomposition equation is as follows:
Peroxide cross-linking agent is dual-tert-butyl peroxy isopropyl base benzene BIPB, for regulating the crosslink density of material,
The amount of hydrogen peroxide cross-linking agent must well control, cross the most at least during sulfur foam crosslink density low cause molten
The low bag of body intensity does not lives gas and forms continuous aperture structure and maybe cannot foam；Cross and cross-link during sulfur foam at most
Density is the highest causes melt strength the highest and expansion ratio is little maybe cannot foam.
Zinc oxide is used as to help blowing promotor, regulates its expansion rate, and content is too low, and foaming agent gas forming amount is little to be caused
Foaming agent consumption increases, expansion rate SC slow curing foamed time energy consumption to be extended increases；Zinc oxide is too much, then send out
Bubble causes rate of closed hole to decline soon, and product resilience is poor.
Stearic acid is used as to help foaming and lubricant, regulation expansion rate and antiseized effect in operating process, sends out very little
Steep the most slack-off, material slightly sticky equipment in operation, the most then foam and slightly accelerate, skidding time mixing, it is slow to heat up, and opens
Refining process easy roll release on a mill until.
Various pigment, as coloring agent, give the various deep mixed color of product.
Ground calcium carbonate, as filler, reduces cost, improves foaming nucleation abscess quality, add weight on a small quantity
Matter calcium carbonate can regulate foaming nucleation quality, and a large amount of interpolation is to reduce production cost；Too much interpolation can be made
Product density height, intensity resilience variation, feel is become to be deteriorated.
