Abstract
The invention relates to a body support tool material, especially the gettama gum substrate support tool material, wherein it uses the low fusion point of gettama gum, to foam it to improve the permeability, and adds short fiber to avoid reducing rigidity, to prepare the gettama gum substrate foaming strengthen plate, then stitches it or adhere it with soft curtain pad to obtain the final product.
Description
Technical field
The present invention relates to a kind of human body and protect brace material, especially brace integrated material based on gutta percha substrate.
Background technology
Modern society is owing to fierce social competition, and traffic and motion accident obviously increase.Develop convenient and practical human body and protect the also corresponding increase of demand of brace.High temperature plastics is owing to molding in advance, and processing bothers, and the brace that protects after the molding coincide with position, sick traumatic part owing to size shape is very difficult, uses both inconveniences, also uncomfortable, so replaced by low melting point plastic gradually.Gather 1 as poly-own lactone and synthesis of trans in popular these materials at present, the 4-isoprene, is clamminess bad operation though processing temperature is low after the heating that has; Have because the quality instability causes the shaping size instability, have owing to contain effective catalyst in synthetic, can not satisfy human body and protect the requirement of brace green product.
Summary of the invention
Gutta-percha does not have above-mentioned shortcoming, but machining at low temperature again is to protect one of brace preferred material as human body.But still need further consider breathability in actual use, with the comfortableness of contact skin and can effectively reduce the high impact stresses that rapid movement causes in colliding.Therefore the further improvement of still needing of single gutta-percha material could be satisfied above-mentioned requirements.Need gutta-percha is carried out integrated modification for this reason.
The brace integrated material based on gutta percha substrate that the present invention proposes comprises two parts: the micro-porous permeable short fiber strengthens Cortex Eucommiae glue-line (being that the foaming of gutta-percha substrate strengthens offset plate) and cushion course.It is even to add promoter, activator, filler, short fiber, foaming agent, age resistor and sulfur roller in gutta-percha respectively, makes the ventilative offset plate that strengthens of gutta-percha matrix micropores after the sulfuration; Cushion course is foam rubber, foam plastics, cotton fiber felt pan, synthetic fibers felt pan or felt pad.Gutta-percha substrate offset plate and soft felt pan are sewed up or the bonding ventilative brace integrated material based on gutta percha substrate of high safety and comfort of promptly making.
Particular content of the present invention is: a kind of brace integrated material based on gutta percha substrate, it sneaks into foaming agent with gutta-percha as substrate and vulcanizing system foams, vulcanizes, add short fiber and filler simultaneously and strengthen rigidity, be sulfided at mixing on the roller and sew up or be bonded with soft felt pan again after little foaming strengthens offset plate.
Described foaming agent is sodium bicarbonate or ammonium bicarbonate.
Described vulcanizing system comprises sulfur, accelerant CZ, M, DM or TMTD, activator zinc oxide or magnesium oxide and antioxidant A, D or 264.
Described short fiber is a cotton short fiber, synthetic staple or rayon short fibre's dimension.
Described filler is titanium dioxide, silicon dioxide or calcium carbonate.
Described gutta-percha as substrate is 100 parts of weight, 5～30 parts on short fiber, 10～50 parts of fillers, 4～20 parts of foaming agent, 0.1～1.0 part in sulfur, 0.1～1 part in activator, 0.1～0.8 part of promoter, 0.1～1.0 part in age resistor.
Gutta-percha is sneaked into promoter, activator, filler, short fiber, foaming agent, age resistor and sulfur roller successively after 65～80 degrees centigrade of roller top rolls are soft spare, place again in the press in 130～145 degrees centigrade of press cures 25～40 minutes, promptly obtain the foaming of gutta-percha substrate and strengthen offset plate.
Described soft felt pan is foam rubber, foam plastics, cotton fiber felt pan, synthetic fibers felt pan or felt pad.
The foaming of gutta-percha substrate is strengthened offset plate and soft felt pan stitching or bonding, promptly obtain brace integrated material based on gutta percha substrate.
The specific embodiment
The method for making of this composite material is given an example:
1. gutta-percha 100 restrains, captax 0.8 gram, zinc oxide 1.0 grams, titanium dioxide 30 grams, short cotton fiber 25 grams, sodium bicarbonate 15 grams, antioxidant D 0.8 gram, sulfur 1.0 grams, with 70 degrees centigrade of elder generations of roll surface temperature that Cortex Eucommiae rubber roll is soft on twin-roll machine, it is even to sneak into promoter, activator, filler, short fiber, foaming agent, age resistor and sulfur roller then successively, places in the press in 135 degrees centigrade of press cures 35 minutes again, promptly obtains the ventilative offset plate that strengthens of gutta-percha matrix micropores.Take out the back and on sheet material, punch, sew up with the cotton fiber felt pan of same size shape again and promptly get final product, brace integrated material based on gutta percha substrate
2. gutta-percha 100 restrains, captax 0.8 gram, zinc oxide 1 gram, titanium dioxide 20 grams, calcium carbonate 30 grams, synthetic staple 25 grams, sodium bicarbonate 15 grams, antioxidant 264 0.8 gram, sulfur 1.0 grams, with 70 degrees centigrade of elder generations of roll surface temperature that Cortex Eucommiae rubber roll is soft on twin-roll machine, sneak into promoter, activator, filler, short fiber, foaming agent, age resistor and sulfur roller then successively and spare, place again in the press in 140 degrees centigrade of press cures 40 minutes, promptly obtain the ventilative offset plate that strengthens of gutta-percha matrix micropores.Take out the back according to bonding final product, the brace integrated material based on gutta percha substrate of promptly getting of the foam rubber felt pan of sheet material area and same size shape.
