It is strong that technical problem to be solved by this invention is to provide a kind of comfort sense, waterproof, corrosion resistant sponge ball and preparation method.
The present invention realizes like this, a kind of sponge ball, with human contact towards outward, this sponge ball comprises the first tweed bed of material successively, first PUR rete, compound foamed cotton layer, second PUR rete and compound cashmere shell-fabric layer, described compound cashmere shell-fabric layer comprises the grid cloth bed of material contacted with the second PUR rete, the second tweed bed of material mutually bonding with the nylon fishing without hook of device to be used, adhesion foamed cotton layer between the grid cloth bed of material and the second tweed bed of material, wherein, the size of compound foamed cotton layer is less than other each layers, the surrounding of compound foamed cotton layer passes through heat seal, first PUR rete and the second PUR rete are adhesive into one, the another side of the first PUR rete sticks on the first tweed bed of material, the another side of the second PUR rete sticks to compound cashmere shell-fabric layer, there is in the middle of being formed the capsule of compound foamed cotton layer, the center position of described second PUR rete has air-vent.
Further, described compound foamed cotton layer comprises the rigid poly urethanes foamed material layer and polyurethane flexible foamed material layer that are adhesive into one, described rigid poly urethanes foamed material layer is positioned at the side of the second PUR rete, and flexibel polyurethane foamed material layer is positioned at the side of the first PUR rete.
Further, described foamed cotton layer is polyurethane flexible expanded material.
Further, the first tweed bed of material and the second tweed bed of material are adopted as undercoat suede terylene cloth, and the first PUR rete and the second PUR rete hot melt adhesive film adopt polyurethane hot melt adhesive film.
A preparation method for sponge ball, comprises following step:
1) size is pruned:
The first tweed bed of material, the first PUR rete, compound foamed cotton layer, the second PUR rete and compound cashmere shell-fabric layer are carried out the amendment of size, compound foamed cotton layer is less than other layer of size;
2) dazzling:
The center of the second PUR rete, pricks upper a few round eye needle set by the second PUR rete, is convenient in the process of heat seal extruding, Exhaust Gas;
3) laying:
The first tweed bed of material, the first PUR rete, compound foamed cotton layer, the second PUR rete and compound cashmere shell-fabric layer are completed successively according to the order of sequence;
4) heat-seal mould is installed:
Required mould is installed on heat seal machine, mould bottom surface and board level to be kept in the process of installing, will ensure that mould is installed wants firmly simultaneously, in order to avoid come off, described die space size is identical with compound foamed cotton layer, ensure that mould is when extruding heat seal, hot thread is in the surrounding of compound foamed cotton layer;
5) after mould rising being improved, the first tweed bed of material, the first PUR rete, compound foamed cotton layer are first put in the middle of mould, with hand, the outmost first tweed bed of material is outwards pullled, so that the fold that the minimizing extruding first tweed bed of material produces;
6) the second PUR rete and compound cashmere shell-fabric layer are put into immediately below mould mouth;
7) foot-propelled matched moulds, is simultaneously extended to the material that die edge exposes the outside that mould mouth prolongs as far as possible, prepares hot synthetic type; The temperature of heat seal is 160 DEG C ~ 180 DEG C.
The present invention compared with prior art, beneficial effect is: the sponge ball of structure of the present invention exists in capsule because compound foamed cotton layer is in one, when human motion, compound foamed cotton layer with can move along with the movement of human body in capsule, because frictional force is little between the grid cloth bed of material of compound foamed cotton layer and the second PUR rete and compound cashmere shell-fabric layer, when being arranged in the helmet or other device, can the slippage along with the motion of human body, reduce frictional force, prevent due to external force, when device mobile human body can not move, cause the infringement to cervical vertebra or other positions of human body, middle compound foamed cotton layer, effect is the effect playing external buffer.The second tweed bed of material of the compound cashmere shell-fabric layer of outermost one deck, effect makes sponge ball can be effectively bonding with nylon fishing without hook.
Compound foamed cotton layer is made by the polyurethane foam material of two-layer different hardness, and near nexine is soft material, the effect of protection human organ.Near outer field hard material, resist destructive power.
Compound foamed cotton layer in sponge ball structure of the present invention has that soft or hard is two-layer to be composited, the interior effect playing buffering to outward, in addition, first PUR rete, the second PUR rete, play the effect of waterproof at the compound foam layer segment of centre, play the effect of heat seal adhesion in the surrounding of compound foamed cotton layer.
The advantage of preparation method of the present invention is mainly shaping by the mode of mould heat seal, and complete mechanization production, efficiency is high.Quality is good, and the Magic ball edge after heat seal can not layering, cracking.
The field of the present invention's application is relatively more extensive, has lining of helmet pad, automobile and aircraft Large-sized Communication instrument liner, individual soldier protection harness liner (such as bullet-proof vest cushion, anti-land mine footwear liner, protective garment liner etc.).
