Oriental Lacquer

Oriental lacquer, a natural and renewable polymeric coating, comes from the sap produced by lacquer trees. For practical application, oriental lacquer must be refined to reduce excess water and enhance its quality. In this study, drying oils were blended with oriental lacquer during the refining process to prepare an oil-modified refined lacquer (OMRL). The type and adding amount (0, 10, and 20% by wt.) of drying oils for wood coatings utilization were evaluated. Rhus succedanea oriental lacquer is composed of 54.1% urushiols, 34.3% water, 7.2% plant gum, and 4.4% nitrogenous compounds, and drying oils, including tung oil (TO), linseed oil (LO), and dehydrated castor oil (DCO) were used as materials in this study. The results show that the drying oil acts as a diluent, which reduces the viscosity and enhances the workability and could shorten the touch-free drying time and speed up the hardened drying of the OMRL. The results also indicate that the hardness, mass retention, Tg, tensile strength, abrasion resistance, and lightfastness of OMRL films decrease as more drying oils are blended. Conversely, the bending resistance, elongation at break, impact resistance increase, and particularly, the gloss, is greatly improved through the blending of more drying oils. In conclusion, the LO-modified refined lacquer (RL) has the highest film gloss and the DCO-modified RL has the shortest drying time for coating; otherwise, the film properties are similar among the three types of drying oil.

This paper presents results from the examination of a set of experimental samples using fibre optic reflectance spectroscopy (FORS) and diffuse reflectance imaging spectroscopy in the short-wave infrared (SWIR) range, combined with statistical analysis of the data for the discrimination and mapping of poppy and linseed oil. The aim was to evaluate the efficacy of this non-invasive approach for the study of paint samples with a view to the application of the method for characterisation of the two drying oils in painted art. The approach allowed discrimination between the two drying oils based on FORS spectra and the hyperspectral cube, indicating the influence of the spectral region around 1700 nm on the statistical discrimination based on the anti-symmetric and symmetric first overtone stretching of methylenic CH2 groups. This method is being studied as a potential non-invasive method of organic analysis of oil types that have formerly been studied using gas chromatography-mass spectrometry (GC-MS), which requires micro-samples.

Oil Films

British Columbia pilchard oil dries more rapidly than linseed oil and yields substantial protective films. The films are softer and more tacky than those from linseed oil. They are more permeable to moisture, and show a tendency to become dull and to bloom. These defects can partly be corrected by the use of the proper drier combinations and incorporation of gums but they can be entirely eliminated only by steam distillation of the polymerized oil at high temperatures. The product of this treatment yields films superior to those of other drying oils in hardness, gloss, lower permeability and freedom from yellowing and blooming. The structure and properties of the films are discussed. The nature and distribution of the non-drying components in the film are described. Methods for estimating permeability and moisture absorption of films given and the influence of moisture as the primary agency in film disintegration is emphasized. The nature of yellowing, cissing and blooming, and methods for correcting these defects in pilchard oil are also discussed.

Ancient Times

In Russia, flax has been cultivated since ancient times; fiber linen fabrics and other products were produce to meet needs of the population and for exchange. Oil flax was a less common crop, but its cultivation is of great interest.In recent years, worldwide interest in the use of flaxseed oil has increased due to its healing properties and high content of linolenic acid. Flaxseed oil removes cholesterol, improves the metabolism of proteins and fats, normalizes blood pressure, and reduces the likelihood of blood clots and tumors. Flaxseed oil reduces the risk of cardiovascular and oncological diseases and allergies. Whole flaxseed is used in various countries as an additive to bread and cereal mixtures. Proteins extracted from flaxseed have a gelatinizing effect and can be used in cooking.Oil flax is a valuable food and industrial crop (seeds, oil, short-fiber, cake and meal). Its seeds contain up to 50% of the most valuable vegetable oil which is the richest source of omega-3 and omega-6. Linseed oil ranks first among industrial oils by the volume of production. It is used in the manufacture of environmentally friendly varnishes, paints, drying oils, which serve as a standard for reliability and durability. Linseed oil is widely used in printing, rubber, electrical and many other industries.

For practical applications, oriental lacquer must be refined to reduce its water content and enhance its quality. In this study, drying oils were blended with oriental lacquer during a refining process to produce oil-modified refined lacquer (OMRL).

The effect of type and amount (0%, 10%, and 20% by wt %) of drying oils added to lacquer on lacquer properties were evaluated. Results show that the drying oils acted as a diluent, which reduced the viscosity, and enhanced workability, shortened touch-free drying time and accelerated the hardened drying of the OMRL. The results also indicated that the hardness, mass retention, Tg, tensile strength, abrasion resistance, and lightfastness of OMRL films decreased as more drying oils were blended with lacquer. Conversely, the bending resistance, elongation at break, impact resistance increased. Gloss was greatly improved through the blending of more drying oils with lacquer. In conclusion, the LO-modified refined lacquer (RL) had the highest film gloss and the DCO-modified RL had the shortest drying time for coating. Otherwise, the film properties were similar among the three types of drying oils.
