"Flexible lead-free gamma-shielding material with flame retardant property and preparation method thereof" provides a flexible lead-free gamma-shielding material with high-temperature silica sulfide as a substrate, which has good flexibility, flame retardant property, mechanical strength and good gamma-shielding material. The preparation method of the shielding material comprises the following steps: plasticating flexible polymer matrix material → modifying the surface of functional filler → mixing with functional filler powder → tabletting and molding at high temperature and normal pressure.
The applicant of the application purchases the nuclear radiation protective clothing fabric of the Hunan Saifugao high and new technology Limited company for processing the nuclear radiation protective clothing, and finds that the functional coating layer (surface glue) has self-adhesion phenomenon in the production process, thereby seriously influencing the production and processing. For this reason, the applicant has conducted a series of studies to solve the problems and, through constant research, test and trial production, has finally developed an anti-blocking coating composition for nuclear radiation protective clothing fabric.
Disclosure of Invention
The invention aims to solve the problem that the production and processing are affected by the mutual adhesion of the conventional nuclear radiation protective clothing fabrics, and provides an anti-adhesion coating composition for the nuclear radiation protective clothing fabrics.
The technical scheme for realizing the purpose of the invention is as follows:
an anti-adhesion coating composition for nuclear radiation protective clothing fabric is prepared by taking a thermoplastic polyurethane elastomer (TPU) and a thermoplastic acrylic resin as main materials and taking a polyurethane prepolymer, a hexamethylene diisocyanate trimer (HDI trimer) and ethyl acetate as auxiliary materials, wherein the weight parts of the raw materials are as follows:
0.5-3 parts of thermoplastic polyurethane elastomer (TPU);
5-15 parts of thermoplastic acrylic resin;
1-8 parts of polyurethane prepolymer;
0.5-5 parts of hexamethylene diisocyanate trimer (HDI trimer);
20-50 parts of ethyl acetate;
the raw materials are all the existing products sold on the market.
The anti-adhesion coating composition for the nuclear radiation protective clothing fabric comprises the following raw materials in parts by weight:
1.5 parts of thermoplastic polyurethane elastomer (TPU);
10 parts of thermoplastic acrylic resin;
4 parts of a polyurethane prepolymer;
2 parts of hexamethylene diisocyanate trimer (HDI trimer);
and 40 parts of ethyl acetate.
The anti-adhesion coating composition for the nuclear radiation protective clothing fabric is prepared by a conventional method. The preparation method comprises weighing the raw materials according to the weight ratio, mixing, stirring at normal temperature, and dissolving to obtain the final product.
When in use, the prepared anti-adhesion adhesive is coated on the surface of a substrate (generally rubber or plastic) of a functional coating layer (surface glue) of the nuclear radiation protective clothing fabric on a glue spreader, and is cured to form a film at a high temperature of 45-70 ℃, and the film can be used after being spread and placed for at least 8 hours, so that the adhesion condition of the surface of the substrate can be improved, and the production and processing are convenient.
The anti-adhesion coating composition comprises main materials of thermoplastic polyurethane elastomer (TPU) and thermoplastic acrylic resin.
The TPU is a high molecular material formed by jointly reacting and polymerizing diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or Toluene Diisocyanate (TDI), etc., and macromolecular polyol and low-molecular polyol (chain extender). Has excellent characteristics of high tension, high tensile force, toughness and aging resistance, and is a mature environment-friendly material. At present, TPU is widely applied to the aspects of medical sanitation, electronic and electric appliances, industry, sports and the like, has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and the like which cannot be compared with other plastic materials, and simultaneously has a plurality of excellent functions of high waterproofness and moisture permeability, wind resistance, cold resistance, antibiosis, mildew resistance, warm keeping, ultraviolet resistance, energy release and the like.
The thermoplastic acrylic resin is a thermoplastic resin prepared by polymerizing acrylic acid, methacrylic acid and derivatives thereof (such as esters, nitriles and amides). Can be repeatedly heated for softening and cooled for solidification, and can be dissolved in appropriate solvent. After the coating solvent prepared by the method is volatilized, a macromolecular poly-integrated film does not generate further crosslinking in the film forming process, has larger relative molecular weight, good light and color retention, water and chemical resistance, quick drying, convenient construction and easy recoating and reworking.
Polyurethane prepolymers are widely used in many fields such as polyurethane adhesives, coatings, elastomers, foams and fibers. The polyurethane adhesive not only has better adaptability to the surfaces of different adhered base materials, but also has larger self cohesive energy and quite high strength. The TPU and the polyurethane prepolymer act together, so that the anti-adhesion property is good.
Hexamethylene Diisocyanate (HDI) trimer, a colorless or yellowish liquid, has a special pungent odor. Slightly soluble in water, slowly reacts in water, and is completely miscible with organic solvents such as esters, ketones, ethers, aromatic hydrocarbons and aliphatic hydrocarbons. The characteristics and the application of the composite material are as follows:
1) HDI is aliphatic isocyanate, and the prepared resin has obvious yellowing resistance;
2) because HDI does not contain aromatic rings, the hardness and the strength of the polyurethane elastomer are not too high, and the flexibility is better;
3) the HDI has higher volatility, generally forms tripolymer by catalysis, is used for manufacturing non-yellowing polyurethane coatings, PU leather and the like, reduces the volatility, and has higher molecular weight and functionality, so that the coatings are easy to dry, and have good mechanical property, good chemical resistance and weather resistance and good adhesion.
Ethyl acetate is also known as ethyl acetate. Pure ethyl acetate is a colorless transparent liquid with pungent odor, and has a Content (CH)3COOC2H5) Not less than 99.5 percent, is a fine chemical product with wide application, has excellent solubility and quick drying property, has wide application, is a very important organic chemical raw material and an extremely good industrial solvent。
In the prior art, the surface coating of the nuclear radiation protective clothing fabric is made of TPU materials, but only the TPU materials are used, so that the effect is not strong. The anti-adhesion coating composition disclosed by the invention adopts two main materials, namely TPU and thermoplastic acrylic resin, and is added with polyurethane prepolymer with relatively large cohesive energy and HDI trimer with excellent yellowing resistance and short drying time, so that the anti-adhesion property, the light and color retention property, the water resistance and the chemical resistance of the coating composition after curing and film forming are enhanced, and the construction time of a gluing process is short and convenient, and recoating and reworking are easy.
The anti-adhesion adhesive prepared from the anti-adhesion coating composition is soft, is coated on a main body material (fabric) of the nuclear radiation protective clothing, and is good in anti-adhesion property, high in strength, good in toughness, wear-resistant and cold-resistant after being cured, is suitable for the requirements of anti-adhesion, aging resistance, water resistance and wear resistance of the main body material of products such as the nuclear radiation protective clothing fabric and the like, and can effectively improve the safety and prolong the service life of the products.
