Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of special functional fabrics, and relates to a special composite material for shooting clothes with elastic recovery effect and a preparation method. BACKGROUND

[0002] The air rifle shooting clothes are a suit of half cloth and half leather, which are actually made of two layers of thick canvas and supplemented by leather. The shooting clothes have a certain hardness and thickness. The thicker the shooting clothes are, the more beneficial it is for the athletes to control and relax the muscles, reduce the influence of heartbeats on the stability of the athletes, and help the athletes support the body and fix the action for a long time, so as to stably and continuously make accurate actions. The shooting clothes have a great influence on the competition results, and can bring an addition of 40 points, so the International Shooting Sport Federation has strict standards for the hardness and thickness of the shooting clothes. The hardness standard is that a standard hardness measuring instrument is used, a 60mm diameter cylinder is used as a bottom surface, a 20mm diameter disc is pressed under a weight of 1.0kg, and the shooting clothes (double-layer canvas) are at least sunken by 3.0mm. The thickness standard is that a standard thickness measuring instrument is used, and the thickness of the shooting clothes (double-layer canvas) is not higher than 2.5mm under a weight of 5.0kg.

[0003] At present, the international high-end brands include Ahg (Germany), Capipie (India), Hitex (Czech Republic) and LECAF (Korea). The special canvas fabrics developed by many brands can provide stability within the shooting clothes standards formulated by the International Shooting Sport Federation to improve the competition results of athletes, such as the EVOTEX fabric independently developed by Hitex and the Capitex fabric independently developed by Capapie, which have the characteristics of not easy to deform and high strength, and can ensure the stability of athletes while providing the required flexibility.

[0004] The canvas fabric used in the shooting clothes produced by the domestic brand (God of Guns) pursues to improve the hardness, so as to improve the supporting effect of the shooting clothes on the athletes, but such fabric causes the problems of inflexibility and discomfort, is easy to deform, the folds are not easy to recover, and the canvas becomes soft after being worn for a long time, which has an adverse effect on the supporting property of the shooting clothes.

[0005] In addition, the domestic shooting clothes mainly provide the hardness and supporting property of the whole shooting clothes by developing additional support layers inside or outside the shooting clothes, such as plastic or rubber panels. Although these support layers can be well sewn or bonded into the clothes, the additional support layers are easy to be separated or adhered from the canvas under different temperature and humidity environments, so that the hardness changes greatly, thereby resulting in poor stability of the shooting clothes.

[0006] Therefore, it is of great significance to research a special composite material for shooting clothes with elastic recovery effect and a preparation method to solve the above problems. SUMMARY

[0007] The present application aims to solve the problems in the prior art and provide a shooting suit special composite material with elastic recovery effect and a preparation method thereof.

[0008] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0009] A shooting suit special composite material with elastic recovery effect is formed by two layers of the composite material superimposed to form a double-layer canvas, the double-layer canvas has a slow recovery effect and meets the standards of the 2017 second edition of the ISSF regulations Part 7 (Rifle) on air rifle shooting clothing, wherein the slow recovery effect refers to that after the double-layer canvas is bent 90° by applying an external force (pressure load 5N, pressure application time 5min), the deformation is restored to the initial state (the "restored to the initial state" means that all performances are completely the same as before bending) within 8-12s after the external force is removed.

[0010] The composite material is composed of canvas fabric and high molecular adhesive, and the thickness of the two layers of composite material is ≤2.5mm, the hardness reading can change within 0-20s, the initial hardness change range is 2.0-2.9, and the final hardness change range is 2.7-3.5, and the hardness meets the ISSF safety rules (see Technical Rules General Regulations Chapters 6 and 7) by using the standard thickness / hardness measuring instrument (ISO 9001:2000) specified by the International Shooting Federation (ISSF).

[0011] According to the mass fraction, the high molecular adhesive includes: glue I 10-30 parts, glue II 15-40 parts, water 15-100 parts, and organic solvent 20-100 parts.

[0012] Glue I is a thermosetting resin glue or a glue with increased hardness to Shore 70-85D after curing, glue II is a thermoplastic resin glue, cross-linking and micro-phase separation can occur between glue I and glue II during the curing reaction; the solubility of glue I in organic solvent is > the solubility of glue I in water.

[0013] The curing process of the composite material: firstly, spray ethanol on the surface of the canvas fabric to wet the canvas, then evenly brush the polymer adhesive on both sides of the canvas fabric using a roller at a mass ratio of 2:1 to 1:2 (canvas fabric: adhesive), after the adhesive fully infiltrates the canvas fabric, transfer it between the flat plates coated with release agent or release paper, then heat-press and cure for 1-5 hours using a two-step heating and one-step holding method, the heat-press holding temperature is 80-170℃, and directly take out at the holding temperature to obtain the special composite material for shooting clothes with elastic recovery effect. The heat-press curing is divided into three zones, using a two-step heating and one-step holding method, firstly heat the oven from room temperature to half of the holding temperature, the heating time is 20-25% of the total heat-press curing time; then heat the oven to the holding temperature, the heating time is 5-10% of the total heat-press curing time; finally, hold at this temperature, the time is 65-75% of the total heat-press curing time.

[0014] The obtained composite material is characterized in that, after applying an external force (pressure load 5N, pressure time 5min) to bend the composite canvas by 90°, the deformation is restored to the initial state within 8-12s after the external force is removed; and it has environmental stability, the hardness change is less than 0.2 after placing the composite material in the constant temperature and humidity chamber for 1h at a relative humidity of 10-70% and a temperature of 10-65℃, the final hardness change is less than 0.2, and the performance is stable.

[0015] As a preferred technical solution:

[0016] The special composite material for shooting clothes with elastic recovery effect as described above, the canvas fabric material is cotton, hemp, polyester, polyester cotton, nylon, spandex or a blended fabric of at least two of them.

[0017] The special composite material for shooting clothes with elastic recovery effect as described above, the canvas fabric is a plain weave structure, a twill weave structure or a satin weave structure formed by interweaving the warp and weft yarns up and down.

[0018] The special composite material for shooting clothes with elastic recovery effect as described above, the single-layer canvas fabric thickness is 0.9-1.3mm. The thickness of the canvas in this value range ensures that the canvas can still meet the optimal parameters required by the International Shooting Federation for shooting clothes competition after being coated with adhesive and heat-pressed and cured, avoiding that the canvas is too small to provide sufficient support for shooting athletes, and avoiding that the thickness is too large to meet the thickness standard of the International Shooting Federation for shooting clothes.

[0019] The special composite material for shooting clothes with elastic recovery effect as described above, the epoxy resin glue is epoxy resin bisphenol A type glue, epoxy resin bisphenol F type glue or epoxy resin bisphenol S type glue; the acrylic ester glue is methyl acrylate glue or cyano acrylate glue; the polyurethane glue is polyisocyanate-based polyurethane glue or hydroxyl polyurethane glue; the polyimide glue is condensation type polyimide glue or addition type polyimide glue; the vinyl acetate glue is vinyl acetate-ethylene copolymer glue; the natural rubber is natural latex or cellulose glue; and the synthetic rubber is chlorobutyl rubber or nitrile rubber.

[0020] The special composite material for shooting clothes with elastic recovery effect as described above, the epoxy resin glue is epoxy resin bisphenol A type glue, epoxy resin bisphenol F type glue or epoxy resin bisphenol S type glue; the acrylic ester glue is methyl acrylate glue or cyano acrylate glue; the polyurethane glue is polyisocyanate-based polyurethane glue or hydroxyl polyurethane glue; the polyimide glue is condensation type polyimide glue or addition type polyimide glue; the vinyl acetate glue is vinyl acetate-ethylene copolymer glue; the natural rubber is natural latex or cellulose glue; and the synthetic rubber is chlorobutyl rubber or nitrile rubber.

[0021] The application further provides a preparation method of the special composite material for shooting clothes with elastic recovery effect as described above, which comprises the following steps: firstly, spraying ethanol on the surface of the canvas base cloth to wet the canvas; then, uniformly brushing the high-molecular adhesive on the front and back surfaces of the canvas base cloth by using a roller; after the high-molecular adhesive completely infiltrates the canvas base cloth, transferring the canvas base cloth between the flat plates coated with a release agent or laid with release paper; and finally, taking out the special composite material for shooting clothes with elastic recovery effect at a holding temperature after hot-pressing and curing.

[0022] If the polymer relaxation process cannot timely adapt to the cooling speed, the chain segment will be frozen, and thus the glass transition occurs. From the high-elastic state to the glass state, the conformation needs to be changed and the volume needs to be shrunk, and the composite material will obtain higher hardness in these processes. Conversely, if the temperature is slowly lowered, the polymer can well adapt to the change of the temperature in the relaxation process, and the chain segment can still move for a period of time, and thus the composite material does not have high hardness in the macroscopic aspect.

[0023] As a preferred technical scheme:

[0024] The preparation method of the special composite material for shooting clothes with elastic recovery effect as described above, the mass ratio of the canvas base cloth to the high-molecular adhesive is 1:2-2:1.

[0025] The preparation method of the special composite material for shooting clothes with elastic recovery effect as described above, the hot-pressing and curing is divided into three zones, and the two-step heating and one-step holding mode is adopted for the hot-pressing and curing.

[0026] The hot-pressing curing process is specifically: firstly, heating from room temperature to half of the holding temperature, the heating time is 20-25% of the total hot-pressing curing time, then continuing to heat to the holding temperature, the heating time is 5-10% of the total hot-pressing curing time; finally, holding at the holding temperature, the holding time is 65-75% of the total hot-pressing curing time; the first step heating speed in this range can avoid the phenomenon of uneven distribution of the adhesive after curing due to too fast solvent evaporation; the second step heating speed in this range can promote the crosslinking of the adhesive and improve the efficiency; the third step holding time in this range can ensure the complete crosslinking of the adhesive to give the composite material the elastic recovery behavior;

[0027] The preparation method of the special composite material for shooting clothes with elastic recovery effect as described above, the holding temperature is 80-170 DEG C, and the total hot-pressing curing time is 1-5 h; the holding temperature in this range can avoid too low temperature, which makes the molecular chain movement of the adhesive difficult and the curing reaction unable to complete, and also can avoid too high temperature, which causes the adhesive to flow or the adhesive layer to be brittle; the hot-pressing curing time in this range can avoid incomplete evaporation of the organic solvent due to too short time, a small amount of crosslinking of the polymer adhesive, soft adhesive with certain viscosity, influence on the use of the canvas and the hardness and thickness of the canvas cannot meet the requirements of the shooting clothes, and also can avoid too long time, which leads to too high crosslinking density, increased hardness of the adhesive and too hard canvas that cannot meet the requirements of the International Shooting Federation.

[0028] The principle of the present application is as follows:

[0029] The adhesive (i.e. the polymer adhesive) of the structure of "organic solvent-adhesive I-adhesive II-water" is connected through chemical bonds or chain segments after heating, realizes the step-by-step polycondensation of the multifunctional monomers, the polyaddition of the multifunctional monomers and the crosslinking reaction of the linear or branched molecules, and thus forms three-dimensional space network macromolecules, i.e. the crosslinking structure; the crosslinking structure formed on the surface and inside of the canvas after the mixture is combined with the canvas blank provides certain elasticity on the basis of meeting the requirements of the shooting clothes on the hardness of the fabric. In addition, the crosslinking points between the chains generated by the crosslinking inhibit the sliding between the polymer chains, and thus the performance of the polymer adhesive is different at different crosslinking degrees: when the crosslinking degree is low, it is helpful for the directional arrangement and stretching crystallization of the molecular chains, the chain segments between the crosslinking points can still move, and the elasticity is good; when the crosslinking degree is high, the hardness increases and the elasticity decreases, and if the crosslinking degree continues to increase, the crosslinking network hinders the directional arrangement of the molecular chains and hinders the crystallization, and at the same time, the unevenness of the distribution of the crosslinking bonds is also increased, the mechanical strength and the hardness are increased, the stress distribution is more uneven, and finally the elasticity is lost and the material becomes brittle. Therefore, it is necessary to reasonably control the contents of various adhesives and solvents, the crosslinking and curing temperature, the pressure and the time.

[0030] Beneficial effects:

[0031] (1) The special composite material for shooting clothes with elastic recovery effect can provide better support on the basis of meeting the minimum standard of the International Shooting Federation for the thickness / hardness of shooting clothes, and the composite material prepared by single glue and canvas fabric is too hard or too soft, the too hard one cannot meet the strict standard of the International Shooting Federation for shooting clothes, and the too soft one cannot provide the necessary support; on the other hand, the cross-linking structure is formed on the surface and inside of the canvas after the curing of the adhesive, which endows the composite material with slow rebound characteristics, ensures the return to the initial state after testing and bending to provide support, and improves the durability of the clothes;

[0032] (2) The preparation method of the special composite material for shooting clothes with elastic recovery effect accurately controls the parameters of each process step of preparing the composite material, and the prepared double-layer canvas has environmental stability, and can still maintain stable hardness performance under extreme temperature and relative humidity, so as to adapt to the competition environment of different countries and regions and provide stable support;

[0033] (3) The double-layer canvas prepared by the application has initial hardness and final hardness lower than the fabric used in Indian Capapie clothes, and the support has exceeded the similar clothes of international brands such as India;

[0034] (4) Based on the double-layer canvas prepared by the application, a complete set of shooting clothes sample has been prepared, and the preparation period is 7-14 days, which greatly reduces the time cost, money cost and later maintenance cost of ordering from abroad, and maximizes the realization of private customization demand.
