Technical Field
The invention belongs to the technical field of special functional fabrics, and relates to a special composite material with an elastic recovery effect for shooting clothes and a preparation method thereof.
Background
The air rifle shooting suit is a half-cloth half-leather suit, is actually made by superposing two layers of thick canvas and is assisted by leather. The shooting suit has certain hardness and thickness, and the thicker the shooting suit is, the more is favorable for controlling and relaxing muscles of the athlete, reduces the influence of heart beating on the stability of the athlete, and helps the athlete support the body and fix the action for a long time, so that the accurate action is stably and continuously made. The shooting suit has great influence on the performance of the match, and can bring about 40 minutes of addition, so that the international shooting union has strict standard on the hardness thickness of the shooting suit. The hardness standard is that a standard hardness measuring instrument is used, a measuring cylinder with the diameter of 60mm is used as the bottom surface, a measuring disc with the diameter of 20mm is pressed under the condition of weighing 1.0kg, the shooting suit fabric (double-layer canvas) is sunken by at least 3.0mm, and the thickness standard is that the thickness of the shooting suit (double-layer canvas) is not higher than 2.5mm under the condition of weighing 5.0kg by using the standard thickness measuring instrument.
Currently, international existing high-end brands are Ahg (germany), capipie (india), hitex (czech), LECAF (korea). The special canvas fabric developed by multiple brands can provide stability in the shooting suit standard established by internationally shooting union to improve the game performance of athletes, such as EVOTEX fabric independently researched and developed by Hitex and Capitex fabric independently researched and developed by Capapie, has the characteristics of difficult deformation and high resistance, and provides required flexibility while guaranteeing stability for athletes.
Canvas fabrics used for shooting clothes produced by domestic brands (god guns) are pursued to improve hardness, the supporting effect of the shooting clothes on athletes is improved by providing larger hardness, but the fabric causes the problems of inflexibility and discomfort, is easy to deform, folds are not easy to recover, and after being worn for a long time, canvas becomes soft, and the supporting effect of the shooting clothes is adversely affected.
In addition, the domestic shooting suit mainly provides the hardness and the support of the whole shooting suit by developing additional support layers which are added inside or outside the shooting suit, such as plastic or rubber panels, and the support layers can be well sewn or adhered into the suit, but the additional support layers are easy to separate from or adhere to canvas at interfaces under different temperature and humidity environments, so that the hardness change span is larger, and the stability of the shooting suit is poor.
Therefore, the special composite material for the shooting suit with the elastic recovery effect and the preparation method thereof are researched to solve the problems, and have very important significance.

If the polymer is not suitable for the cooling speed in time in the relaxation process, the chain segment is frozen, and glass transition occurs. From the high-elastic state to the glassy state, the processes of conformational transition and volume shrinkage are required, and the composite materials can obtain higher hardness in the processes. On the contrary, if the temperature is slowly lowered, the polymer can well adapt to the change of temperature in the relaxation process, and the chain segment can also move in a period of time, so that the macroscopic composite material has no high hardness.
As a preferable technical scheme:
according to the preparation method of the special composite material with the elastic recovery effect for the shooting suit, the mass ratio of the canvas grey cloth to the high polymer adhesive is 1:2-2:1.

The preparation method of the special composite material for the shooting suit with the elastic recovery effect has the advantages that the heat preservation temperature is 80-170 ℃, the total hot pressing and curing time is 1-5 h, the heat preservation temperature is in the range, the problems that the temperature is too low, the molecular chain of an adhesive is difficult to move, the curing reaction cannot be completed, the glue solution is lost or the glue layer is embrittled due to the fact that the temperature is too high can be avoided, the hot pressing and curing time is in the range, the situation that the organic solvent is incompletely volatilized due to too short time, the high-molecular adhesive is slightly crosslinked, the glue is soft and still has certain viscosity, the use of the canvas is affected, the hardness and the thickness of the canvas cannot meet the requirements of the shooting suit, too long time can be avoided, the crosslinking density is too high, the hardness of the glue canvas is too hard, and the match requirements of the international shooting union on the shooting suit cannot be met.
The principle of the invention is as follows:
After the glue with the structure of organic solvent-glue I-glue II-water (namely, the high-molecular adhesive) is heated, the gradual polycondensation of the multi-functional monomer, the polyaddition of the multi-functional monomer and the crosslinking reaction of linear or branched molecules are realized through chemical bond or chain segment connection, so that a three-dimensional space network macromolecule is formed, namely, a crosslinked structure is formed, after the mixture is compounded with canvas embryo cloth, the crosslinked structure formed on the surface and inside of the canvas shows mechanical strength, provides certain elasticity, and endows the canvas with slow rebound resilience on the basis of meeting the requirement of shooting clothes on the hardness of the fabric. In addition, the crosslinking points between the chains generated by crosslinking inhibit sliding among the polymer chains, so that the polymer adhesive has different crosslinking degrees and different performances, namely, the polymer adhesive is favorable for directional arrangement and stretching crystallization of the molecular chains during light crosslinking, chain segments among the crosslinking points can still move, the elasticity is good, the crosslinking degree is high, the hardness is increased, the elasticity is weakened, if the crosslinking degree is continuously increased, the crosslinking density is excessively high, a crosslinking network hinders the directional arrangement of the molecular chains, crystallization is hindered, meanwhile, the non-uniformity of the distribution of the crosslinking bonds is aggravated, the mechanical strength and the hardness are both increased, and the stress distribution is more non-uniform and finally loses elasticity to become brittle. Therefore, various glue contents and solvent contents of the adhesive are required to be reasonably controlled, and the crosslinking curing temperature, pressure and time are required to be reasonably controlled.
The beneficial effects are that:
(1) The special composite material for the shooting suit with the elastic recovery effect can provide better support on the basis of meeting the minimum standard of internationally jetting pair shooting suit thickness/hardness, and the composite material prepared by single rubber and canvas embryo cloth is too hard or too soft and can not meet the strict standard of internationally jetting pair shooting suit and is too soft to provide necessary support;
