Adjustable photochromic materials


Vary the type of material, usually in the range of 0.5 to 50. More than two compounds in the polymer to form covalent binding. The photochromic material (ie polymers) to create their own begging Bodhisattva kx. '-42 Research lining with the manufacture of resins and other products prepared photochromic coating is very simple. Simply dissolved in the polymer commonly used organic solvents (such as toluene, etc.) can be, polymer content in the coating to 1 ~ 5O suitable, preferably 5 ~ 4O. Inorganic material was coated glass, cloth, wood, paper, metal, plastic, ceramics, shape is not limited. No special requirements the methods applied coating thickness of 0.5 ~ 50am appropriate, generally do not thin at 5, am. Sun glasses, color, etc. to the method of production of the windshield is the easiest. In order to improve such as hair color and photochromic properties like the depth of the bedding material can also add an appropriate amount of sensitizing agents, such as ultraviolet absorption Jing. Implementation of the inverted (1) photochromic polymer modulation: 40 octyl methacrylate (weight, same below), methyl methacrylate 'n a n-butyl methacrylate l9 lO copies of copies, six 2 , 6,6 a four-methyl-4-methyl acrylate of a l0 piperidine were the biggest blue absorption 600rim the photochromic monomer l, 3,3 one-three a-methyl allyl methyl indole 9r Hao phenol spiro indole hydrochloride 8 copies of naphthalene, the maximum red absorption spectrum 530rim the photochromic monomer 1,3,3 a thirteen-methyl 4,7-dichloro-a 6r a (4-methyl-propenyl Hydroxypiperidine pyridine) spiro [indole-ethylamine a 2,3 a (3H) a naphthalene (2,1,6) (1,4)] Hey triazine 2 copies of hydroxyethyl methacrylate ester of a lO-2 copies l methacrylate were to azo compounds as the initiator, toluene as solvent, nitrogen atmosphere, to 7o ~ 8O ℃ line solution polymerization 7 hours, have solid accounting 5O photochromic polymer; (2) coatings prepared by a naphthalene as the solvent, dubbed the polymer coating solids accounted for 3O; (3) coating and heat curing: water coating the above coating method in 1.0mm thick sheet of glass on the formation of 20. u. m thick coating. Coated glass after heating to 130 ~ C l hour, curing the coating; (4) Performance Test: To observe the coating surface, the ultraviolet light emitted by chemical (2.8mW/cra) exposure, measured tones and color depth results, transparency, good rubber membrane, the appearance of good, ultraviolet light, the deep purple. The coating solvent resistance, weather resistance, long lasting, just change the photochromic compounds, the end product can choose colors.

A z; a hair with a heat storage material is well known that iron and other compounds of gold lip powder or powder, the coexistence in the air and water conditions, the exothermic reaction can occur. Had previously been placed in such material can be heat breathable pocket containers, used in conjunction with barrel curls hair. When the water, the container heat, so hair continuously maintain a high temperature tube to help hair styling. As such exothermic reaction depends on the chemical reaction, therefore, materials, heat is off, can not be reused. Developed into the mid-70s can reuse the hair with heat storage material, but when such materials are the liquid heat storage. Must be packaged in a sealed container when the weight of heavy use, the operating inconvenience, and curly hair are also uncomfortable, and will leak accident. This paper describes a can re-use,[link widoczny dla zalogowanych], non-liquid hair with a heat storage material. This material is light weight, easy to use and comfortable. The composition of this material are mainly two types one is alkanes, is storage, heat the main body; the other is hydrocarbon organic polymers, including synthetic rubber and thermoplastic rubber hydrocarbon, olefin polymers, etc. , Jing used mainly for bonding. Alkanes used in the present invention compounds are paraffin wax, yellow wax, stearic acid and palmitic acid, polyvinyl alcohols, can be used alone, two or more can also be mixed. These compounds of the transition temperature must be at room temperature (minimum temperature of application materials) to between 100 ℃, the best room in the room temperature to 8O ℃. Hydrocarbon used in organic polymers, the main base for the hydrocarbon chain composed of other components in the main chain, such as O, N, si, halogen share of the weight of not more than l0%, preferably less than 5%. Among them, polyolefin there are specific polymethylene, polyethylene, polypropylene, etc. Q - olefin polymer were, between the olefin oligomer, a one olefin and ethyl acetate or ethyl acrylate, such as single oligomers between the body and the light halogenated polymers such as polymers.
