The essential oil is a liquid with fragrance extracted or distilled from flowers, leaves, wood, other plant sources and other animals and plants. Essential oils are not oils like linseed oil or petroleum, in the sense that essential oils are not true oils. Clove oil, lavender oil, peppermint oil and rosemary oil are sometimes used for oily paints, polishes and cleaners.
Polyurea is an elastomeric material formed by the reaction of an isocyanate component and an amino compound component. The polyurea is divided into pure polyurea and semi-polyurea, the performances of the pure polyurea and the semi-polyurea are different, and the most basic characteristics of the polyurea are corrosion resistance, water resistance, wear resistance and the like.
Polyurethane (PU), the full name of which is polyurethane, is a high molecular compound. This product was produced in 1937 by Otto Bayer et al. Polyurethanes fall into the two main categories of polyester and polyether. They can be made into polyurethane plastics (mainly foamed plastics), polyurethane fiber (Chinese called spandex), polyurethane rubber and elastomer. The soft polyurethane mainly has a thermoplastic linear structure, and has better stability, chemical resistance, rebound resilience and mechanical property and smaller compression deformability than a PVC foaming material. Good heat insulation, sound insulation, shock resistance and gas defense performance. Therefore, the product is used as a packaging, sound insulation and filtering material. The hard polyurethane plastic has the advantages of light weight, excellent sound insulation and heat insulation performance, chemical resistance, good electrical property, easy processing and low water absorption rate. It is mainly used as a heat-insulating structural material in the building, automobile and aviation industries. The polyurethane elastomer has the performance between that of plastic and rubber, and has the advantages of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Is mainly used in the shoe making industry and the medical industry. The polyurethane can also be used for preparing adhesives, coatings, synthetic leather and the like.
Sodium alginate is a byproduct after iodine and mannitol are extracted from brown algae such as kelp or gulfweed, the molecule of the sodium alginate is formed by connecting beta-D-mannuronic acid (beta-D-mannuronic acid, M) and alpha-L-guluronic acid (alpha-L-guluronic acid, G) according to a (1 → 4) bond, and the sodium alginate is a natural polysaccharide and has stability, solubility, viscosity and safety required by pharmaceutical preparation auxiliary materials. Sodium alginate has been widely used in the food industry and in the medical field.
The polyethylene glycol dimethacrylate is a high polymer polymerized by ethylene glycol dimethacrylate monomers, and has good thermal stability and no toxicity.
The natural cellulose is polysaccharide which is most widely distributed and contained in nature, and has abundant sources. Current cellulose modification technologies focus primarily on both etherification and esterification. Carboxymethylation is one of the etherification techniques. Carboxymethyl cellulose (CMC) is obtained after carboxymethylation of cellulose, and an aqueous solution of the carboxymethyl cellulose has the effects of thickening, film forming, adhesion, water retention, colloid protection, emulsification, suspension and the like, is widely applied to industries such as petroleum, food, medicine, textile, paper making and the like, and is one of the most important cellulose ethers.
Cyclodextrin (CD) is a generic name for a series of cyclic oligosaccharides produced by amylose under the action of Cyclodextrin glucosyltransferase produced by Bacillus, and generally contains 6-12D-glucopyranose units. Among them, the more studied and of great practical importance are molecules containing 6, 7, 8 glucose units, called alpha-, beta-and gama-cyclodextrins, respectively. Based on the results of X-ray crystallography, infrared spectroscopy and NMR spectroscopy, each D (+) -glucopyranose constituting the cyclodextrin molecule is determined to be in a chair conformation. Each glucose unit is bonded to form a ring by a 1, 4-glycosidic bond. Cyclodextrins are not cylindrical molecules but rather slightly conical rings, since the glycosidic bond linking the glucose units cannot rotate freely.
Hydroxyalkyl starches are a class of starch derivatives, non-ionic. The starch suspension is prepared by heating and reacting ethylene oxide or propylene oxide with alkali as a catalyst and sodium sulfate as a gel-resisting agent. Along with the increase of the substitution degree of hydroxyalkyl, the gelatinization temperature of starch is reduced, the solubility, the transparency and the low-temperature stability of the starch are correspondingly improved, and particularly, the film has good film forming property, and is transparent, flexible, smooth and good in folding resistance. The surface sizing agent can improve the strength of paper surface and improve the printing glossiness of the ink. The product can be used as pigment coating puffy agent alone or in combination with synthetic latex, and can provide high Guo intensity and good printability. It can also be used as a private agent for labels, sealing tapes, corrugated boards, etc. It can also be used as food thickener, textile sizing agent and plasma substitute in pharmaceutical industry to replace dextrose.
Gelatin is a macromolecular hydrocolloid, which is the product of partial hydrolysis of collagen. It can be classified into photographic gelatin, edible gelatin and industrial gelatin according to its properties and uses. The quality requirements for gelatin vary according to the application. When used as an adhesive, the adhesive strength is mainly required. When the product is used in the fields of photography, food, medicine and the like, the purity of the product is emphasized. Collagen molecule is a spiral body formed by three polypeptide chains intertwining with each other, and through the treatment of the technological process, the spiral body of the collagen molecule is degenerated and decomposed into an alpha-component of a single polypeptide chain (alpha-chain), a beta-component consisting of two alpha chains, a gamma-component consisting of three alpha chains, and molecular chain fragments which are arranged between the alpha-component and the gamma-component and are smaller than the alpha-component or larger than the gamma-component. Therefore, the gelatin is a polydisperse system with a certain molecular weight distribution, and the molecular weight distribution of the gelatin is different due to different process conditions and influences the physical and chemical properties of the gelatin.
Ethanol (ethanol), an organic compound, with a molecular formula of C2H6O, a structural formula of CH3CH2OH or C2H5OH, commonly known as alcohol. The ethanol is a flammable and volatile colorless transparent liquid at normal temperature and normal pressure, has low toxicity, and can not be directly drunk as a pure liquid; has special fragrance and slight irritation; slightly sweet and accompanied by pungent and spicy taste. Inflammable, its vapor can form explosive mixture with air, and it can be dissolved in water in any ratio. Is miscible with chloroform, diethyl ether, methanol, acetone and most other organic solvents.
Deionized water refers to pure water from which impurities in the form of ions have been removed. The "deionization" as specified by the International organization for standardization ISO/TC 147 is defined as: "deionized water completely or incompletely removes ionic species. "the current process mainly adopts RO reverse osmosis method to prepare. The anion and the cation in the water are removed by using the ion exchange resin, but soluble organic matters still exist in the water, so that the ion exchange column can be polluted to reduce the efficacy of the ion exchange column, and the deionized water is easy to cause the reproduction of bacteria after being stored.

Wherein, the aroma coating also comprises the following raw materials in parts by mass:
5-10 parts of an emulsifier.
Emulsifiers are substances which form stable emulsions of a mixture of two or more immiscible components. The principle of action is that during the emulsification process, the dispersed phase is dispersed in the form of droplets (micron-sized) in the continuous phase, and the emulsifier reduces the interfacial tension of the components in the mixed system and forms a firmer film on the surface of the droplets or forms an electric double layer on the surface of the droplets due to the electric charge given by the emulsifier, thus preventing the droplets from aggregating with each other and maintaining a uniform emulsion. From a phase point of view, emulsions are still heterogeneous systems. The dispersed phase in the emulsion can be a water phase or an oil phase, and most of the dispersed phase is the oil phase; the continuous phase may be an oil phase or an aqueous phase, most of which are aqueous. The emulsifier is a surfactant, and has hydrophilic group and lipophilic group in its molecule. To indicate the hydrophilicity or lipophilicity of the emulsifier, a "hydrophilic-lipophilic balance value (HLB value)" is generally used, and the lower the HLB value, the stronger the lipophilicity; conversely, the higher the HLB value, the more hydrophilic it is. The HLB value of each emulsifier varies and a suitable emulsifier must be selected in order to obtain a stable emulsion.
The emulsifier is prepared by mixing polyvinyl alcohol and sodium dodecyl sulfate, wherein the ratio of the polyvinyl alcohol to the sodium dodecyl sulfate is 5: 1-2.
The invention uses the compound emulsifier, so that each component can form a very stable emulsion after being stirred, and the components can not be layered after being stored for a long time.
Polyvinyl alcohol is an organic compound with a chemical formula of [ C2H4O ] n, is white flaky, flocculent or powdery solid in appearance, and is odorless. Polyvinyl alcohol is an important chemical raw material, and is used for manufacturing polyvinyl acetal, gasoline-resistant pipelines, vinylon, fabric treating agents, emulsifiers, paper coatings, adhesives, glue and the like.
Sodium dodecyl sulfate is an organic substance of formula C12H25SO4Na, white or pale yellow powder, soluble in water and not sensitive to alkali and hard water. Has the advantages of decontamination, emulsification and excellent foaming power. Is an anionic surfactant which is slightly toxic to human bodies. The biological degradation degree is more than 90%.
Wherein, the aroma coating also comprises the following raw materials in parts by mass:
10-15 parts of essential oil volatilization inhibitor.
The essential oil volatilization inhibitor is prepared by mixing glycerol and paraffin oil, wherein the ratio of the glycerol to the paraffin oil is 4: 1-2.
The compound essential oil volatilization inhibitor is used, so that the volatility of the essential oil can be further slowed down, and the time for releasing the fragrance of the impregnated bond paper is greatly prolonged.
Glycerin is a colorless, odorless, sweet, clear, thick liquid, chemically known as "glycerol". Glycerin is usually extracted from fats and oils. The glycerol has strong hygroscopicity, and pure glycerol can absorb 40% of water, so that a film can be formed when the glycerol is applied on the skin, the effects of isolating air and preventing water evaporation are achieved, and the water in the air can be absorbed. Glycerol is an important chemical raw material and can be used for manufacturing plastics, synthetic fibers, explosives and the like.
Paraffin oil is a mineral oil, and is a colorless and odorless mixture obtained from the fractional distillation of crude oil. The main component is C, H, and the chemical element symbol is CxHy, and can be used in food, medicine and industry.
The impregnated bond paper substrate is formed by impregnating plain base paper or printing decorative paper with a mixed resin adhesive and drying, wherein the mixed resin adhesive comprises the following raw materials in parts by mass:
20-40 parts of polyurethane
30-50 parts of acrylic resin
10-20 parts of epoxy resin
5-10 parts of polymethyl methacrylate
4-6 parts of curing agent
60-80 parts of ethanol.
The mixed resin adhesive disclosed by the invention does not contain formaldehyde, is environment-friendly and pollution-free, and effectively guarantees the body health of users.
Acrylic resin (acrylic resin) is a generic name for polymers of acrylic acid, methacrylic acid and derivatives thereof. The acrylic resin coating is a thermoplastic or thermosetting resin coating or acrylic radiation coating prepared by using (methyl) acrylic ester and styrene as main components and acrylic resin obtained by copolymerizing with other acrylic ester.
The epoxy resin is a high molecular polymer, has a molecular formula of (C11H12O3) n, and is a general name of a polymer containing more than two epoxy groups in a molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or a polyol. Because of the chemical activity of the epoxy group, the epoxy group can be opened by a plurality of compounds containing active hydrogen, and the epoxy group is cured and crosslinked to form a network structure, so that the epoxy group is a thermosetting resin. The bisphenol A epoxy resin has the largest yield and the most complete variety, and the new modified variety is continuously increased and the quality is continuously improved.
Polymethyl methacrylate (PMMA) is a high molecular polymer, also known as acryl, Acrylic or plexiglass, Lucite (trade name), and is called pressure application in taiwan, and is called as alhaga glue in hong kong, because it has the advantages of high transparency, low cost, easy machining, etc., and is a glass substitute material that is often used in common.
Curing agents, also known as hardeners, curing agents or setting agents, are a class of substances or mixtures that enhance or control the curing reaction. The resin curing is carried out by adding a curing (crosslinking) agent to a thermosetting resin through chemical reactions such as condensation, ring closure, addition or catalysis to cause irreversible change of the thermosetting resin. The curing agent is an indispensable additive, and the curing agent is required to be added when the epoxy resin is used as an adhesive, a coating and a casting material, otherwise, the epoxy resin cannot be cured. The variety of the curing agent has great influence on the mechanical property, heat resistance, water resistance, corrosion resistance and the like of the cured product.
Wherein the mixed resin adhesive also comprises the following raw materials in parts by mass:
3-5 parts of polycarbonate.
The use of polycarbonate can enhance the structural strength and elasticity of the impregnated bond paper.
Polycarbonate (abbreviated as PC in english) is a high molecular polymer containing carbonate groups in its molecular chain, and is classified into various types such as aliphatic, aromatic, aliphatic-aromatic, and the like, depending on the structure of the ester groups. The polycarbonate is colorless and transparent, heat-resistant, impact-resistant and flame-retardant at BI level, and has good mechanical properties at common use temperature.
