A technique of painting with glutinous rice straw

Abstract

The invention relates to a glutinous rice straw picture color spraying technology which adopts glutinous rice straw as base material, and comprises the following steps of firstly, manually flattening a board; spraying a whitening agent onto the surface of the glutinous rice straw; and continuously pressing and locating by a flat pressing machine, and carrying out spray painting on the surface of the glutinous rice straw by means of color spraying through a color spraying machine to improve the production efficiency, wherein an attached material for spraying color pigment is acrylic acid waterproof high-white paint, and has the functions of reducing the absorption of the pigment to the glutinous rice straw and highlighting the contrast between a white ground and the color pigment so as to enable the colors of the picture to be rich in gloss and saturation; due to the color reproduction capability of the attached material, the color density can be increased to more than three times that of common water-based ink. After a seven-color ink color spraying technology is adopted, the tiny color gradation and color change can be well reflected; a product is bright and beautiful in colors, simple and unsophisticated and high in third dimension; after being blended with the glutinous rice straw, the product has functions of environmental protection, damp resistance, insect prevention and corrosion prevention; the appreciation and collection values of the picture are far higher than those of similar products.

Description

technical field [0001] The invention belongs to the technical field of glutinous rice straw painting, and in particular relates to a color spraying process of glutinous rice straw painting. Background technique [0002] Known glutinous rice is an annual herbaceous plant of Gramineae, which is a sticky variety of glutinous rice. It is erect, clustered, and about 1m high. Leaf sheaths glabrous, lower part longer than internodes; ligule membranous and hard, lanceolate, base decelerates on both sides to combine with leaf sheath edge, 5-25mm long, with obvious auricles when young; leaf blade flat, draped Needle-shaped to strip-lanceolate, 30-60cm long and 6-15cm wide. The panicles are loose, curved downward when mature, and the branches are angular and often rough; the spikelets are oblong, compressed on both sides, 6-8mm long, containing 3 florets, and the lower two florets are reduced to only a very small lemma And located under 1 hermaphroditic floret; the glume degenerates,...

Problems solved by technology

[0008] Although the existing craft paintings also have combined paintings with straw as raw materials, they mainly use a few waxy straws as auxiliary embellishments to decorate various straw paintings, resin paintings and stone art paintings, and really use glutinous straw as the main body. There is no painting type of color painting at present. Due to the wide range of materials used for the development of glutinous rice straw painting and the utilization of waste, it can not only solve the income of farmers, but also bring a new type of natural and environmentally friendly painting to the field of handicrafts. It is actually a practical benefit. People's new technology, after searching, no similar products are found on the market, therefore, the present invention is specially researched and developed for this
