Description
Technical field
The invention belongs to product of rubber and plastic technical field, be specifically related to a kind of environmental and durable EVA foam-injection Yoga post.
Background technology
Along with improving constantly of people's living standard, healthyly to receive much attention, the project optimization that Yoga sports improves the health especially, and the desirable appurtenance that the Yoga post person that is exactly yoga exercises is comparatively conventional.
The Yoga post overwhelming majority of selling in the market adopts top layer to be band dapple EVA material, heart to be plastic rigid pipe to pass through to cut, the product of gluing, compression molding, be called for short compression molding Yoga post, this processing method will through 12 procedures, from getting the raw materials ready to the product needed production cycle of 15 days, operation is many, fabrication cycle is long, and utilization rate of raw materials is low: EVA raw sheet adds man-hour by peeling, trimming, chamfering, and the utilization rate of raw sheet can only reach about 70%; Although what adopt in addition is can the glue of meet the requirement of environmental protection, also just the toxicity of talkative gelatin water at present within the scope of acceptable, the not environmental protection of 100%; And the glue splicing seams intensity of EVA material lower than other positions, can shorten the service life of Yoga post; Surface detail nonhomogeneous hardness is large; Because Yoga post facestock makes of the eva foam material that thickness is identical, the pressure suffered by depth difference by decorative pattern in process in the dapple shaper of tape loaded is also different, thus cause product surface hard also just different (difference is at 8-10 degree), therefore a kind of better quality is needed, more environmental and durable Yoga post.
Summary of the invention
For solving the problem, the invention discloses a kind of environmental and durable EVA foam-injection Yoga post, technological process is few, and fabrication cycle is short, do not use glue, guarantee the absolute environmental protection of Yoga post, the Yoga post surfacing produced is without splicing, and hardness is even, decorative pattern skin strength is high, product appearance light, bright in luster, durable in use.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of environmental and durable EVA foam-injection Yoga post, it is characterized in that: comprise massage layer and plastic tube, described massage layer is hollow cylinder, be provided with groove inside massage layer, described plastic tube is arranged in groove, and described massage layer surface is divided into circular arc district and massage district, surface, described circular arc district is circular arc, centre is provided with interval trough, and described massage district is the massage convex point be interspersed, and described massage layer internal diameter is identical with the internal diameter of plastic tube.
As a modification of the present invention, described massage layer surface is provided with Liang Ge circular arc district and massage district.
As a modification of the present invention, described massage convex point is trapezoidal or semicircle or truncated cone-shaped.
A processing technology for environmental and durable EVA foam-injection Yoga post, comprises the following steps:
(1) raw material is prepared: its mass component is: blowing agent: 2-4 part, crosslinking agent: 1-2 part, blowing promotor: 1-2 part, pigment: 2-5 part, inserts: 5-10 part, ethylene-vinyl acetate copolymer: 77-89 part;
(2) by raw material banburying 20-30 minute, temperature 120-125 DEG C, pressure 6-10KG/M in banbury
2condition under raw material stirred, melt discharging;
(3) raw material after step (2) being put into temperature is that the screw extruder of 100-120 DEG C plastifies, extrudes, obtains mixture particle through the air-cooled pelletizing of die orifice, and particle size is 3-5mm;
(4) by mixture particle insulation by foam-injection machine preheat temperature 80-100 DEG C, injection pressure is 500-1000KG/CM
2condition bet be mapped to decorative pattern mould, in mould, temperature is 160-180 DEG C, and pressure is 160-180KG/M
2, pressurize 5-10 minute, massage layer is taken out in die sinking;
(5) plastic tube is loaded fast in the groove of massage layer of step (4);
(6) air-cooled at 15-25 DEG C, massage layer is shunk, is wrapped in plastic tube periphery and forms Yoga post;
(7) slitter edge, inspection, packaging, warehouse-in is repaired.
As a modification of the present invention, described blowing agent is sodium acid carbonate, carbonic hydroammonium, Celogen Az, 4,4 '-OBSH, N, N '-dinitrosopentamethylene tetramine at least one wherein or two or more compositions.
As a modification of the present invention, described crosslinking agent is cumyl peroxide, benzoyl peroxide at least one wherein.
As a modification of the present invention, described blowing promotor is borax, stearic acid, zinc oxide, magnesia at least one wherein.
As a modification of the present invention, described inserts agent is calcium carbonate, talcum powder, kaolin, diatomite, graphite, at least one of carbon black or two or more compositions.
The invention has the beneficial effects as follows:
(1) technological process is few, fabrication cycle is short: foam-injection technique of the present invention is only through flow processs such as batching, granulation, foam-injection, deburring packagings, and through granulation, raw material is without the need to Ageing Treatment, from getting the raw materials ready, product completion only needs 5 day time, and operating efficiency improves 2 times;
(2) utilization rate of raw materials is high: foam-injection technique is injected directly into by compound in the dapple mould of band, finally shrink shaping, therefore eliminate the raw material loss of the peeling in compression molding production technology, trimming, discharge loss link, make raw-material utilization rate reach more than 90%;
(3) do not use glue, guarantee the absolute environmental protection of product, plastic tube be the principle that utilizes plastic products to expand with heat and contract with cold by firm from foam-injection machine the product subsurface temperature of depanning higher, the period that hole size is larger loads fast, along with temperature progressively reduces, superficial layer is by plastic tube tightly Bao Zhu, therefore without glue, (Yoga post production technology is in the past compression molding to the misgivings of not coming unstuck: raw material is made cystosepiment, put 10-15 days, uniformly glue special is coated at cystosepiment and plastic tube, cystosepiment is twisted in plastic tube surface, be placed on extrusion forming in mould again, after this Yoga post time grown, can be come unstuck cracking, and seam),
(4) Yoga post surfacing is without splicing seams: be because the dapple mould of band is under closed state, compound enters mould by the mode of injection, so material does not have seam exactly, product is made to extend more than one times than compression molding Yoga post service life;
(5) surface detail hardness is even: compound in flowing shape fast, can arrive rapidly each position of mould when injecting, and by the pressurize of a period of time, makes surface detail hardness even;
(6) decorative pattern skin strength is high, outward appearance is brighter, durable in use, wherein motion can be unfolded to each position of health by circular arc district, massage is provided with multiple staggered massage convex point in district, powerful massaging can be carried out to the key position of human body, acupoint, reach and release the pressure, loosen the moulding effect of body and mind, body-building; The color of pigment is red, blue, orange, purple, green, black etc., and product color is bright-coloured, colour-fast;
(7) material is simple, and adopt ethylene-vinyl acetate copolymer (EVA) to be major ingredient, the Yoga post cost produced is low, and competitiveness is strong, and craft science, banbury temperature controls below 125 DEG C, and crosslinking agent can not be cross-linked in banbury, guarantees product quality.
