Abstract
The invention relates to a method for manufacturing rice-straw pencils, and belongs to the technical field of light industrial products. The method comprises the steps: utilizing rice straws and an adhesive, mixing, hot pressing, cutting, pencil lead mounting, disinfecting, drying, grinding, polishing and coloring to obtain the rice-straw pencils. According to the method for manufacturing the rice-straw pencils, crop wastes are utilized to replace timbers, the manufacturing process is simple, the production cost is low, products do not contain formaldehyde, no pollution to environment and users exists, and great significance is provided for country environment protection.
Description
Technical field
The present invention relates to a kind of preparation method of rice straw pencil, belong to light industrial goods technical field.
Background technology
Pencil is a kind of attending classes articles for use that people commonly use, in writing pen now, pencil be application quantity maximum be also the most a kind of pen; various pencils in the market make with timber, plastic processing; consume timber, contaminated environment, is unfavorable for environmental protection.The pencil stalk that most possessor uses waste paper to roll, tentatively solve environmental issue, but its productivity ratio is low, and higher to the requirement of paper, consumes the raw materials for production of recycled writing paper.For protecting forest resources and ecological environment, the substitute of active development Wood-bar pencil is produced, and is the inevitable choice that pencil industry further develops.And on the other hand, agricultural crop straw part can not utilize and burn, also to environment.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of rice straw pencil of cheap, alternative timber, in order to solve the shortcoming that prior art exists.
The object of the present invention is achieved like this, and its manufacturing process comprises the following steps: batch mixing-hot pressing-cutting-dress pen core-sterilization-oven dry-polishing-polishing-colouring; Its concrete steps are as follows:
1, batch mixing: after agricultural crop straw screening is cleaned up, be crushed to 70-100 orders, the stalk 75-90 parts after pulverizing and adhesive 20-30 parts put into container mixing and stirring, obtains compound;
2, hot pressing: the compound in 1 is put into pencil moulding press, pencil moulding press is made up of two concentric tubes, and interior pipe is solid tubes, diameter 0.15mm larger than a footpath, and outer tube is hollow circle or hexagon shape, and blend composition installs between two concentric tubes.Described hot pressing, temperature is 120 ~ 150 DEG C, pressure 5Mpa, and the pencil hot pressing time of every mm dia is 0.5min.
3, cut: the pencil of machine-shaping is cut into conventional pencil length; At room temperature natural drying, obtains pencil blank, then loads pen core, at room temperature natural drying, obtains pencil blank;
4, with disinfection by ultraviolet light, dry, finally polish, polishing, colouring process.
Beneficial effect of the present invention is: 1) rice straw belongs to renewable resource, and raw material resources are huge, cheap, substitute timber with stalk, is of great importance to the environmental protection of China.2) utilize wastes of crops, substitute timber, manufacture craft is simple, and production cost is low, the product of production not containing formaldehyde, to environment and user all pollution-free.
Detailed description of the invention
Below in conjunction with specific embodiment, present invention is described:
Embodiment 1
There is provided a kind of preparation method of rice straw pencil in the present embodiment, its needed raw material by weight proportioning is made up of following.
Title quantity
Rice straw 75
Adhesive 25
Its making step:
1, batch mixing: after rice straw, straw screening are cleaned up, be crushed to 70-100 orders, the stalk 75 parts after pulverizing and adhesive 25 parts put into container mixing and stirring, obtains compound;
2, hot pressing: the compound in 1 is put into pencil moulding press, pencil moulding press is made up of two concentric tubes, and interior pipe is solid tubes, diameter 0.15mm larger than a footpath, and outer tube is hollow circle or hexagon shape, and blend composition installs between two concentric tubes.Described hot pressing, temperature is 120 ~ 150 DEG C, pressure 5Mpa, and the pencil hot pressing time of every mm dia is 0.5min.
3, cut: the pencil of machine-shaping is cut into conventional pencil length; At room temperature natural drying, obtains pencil blank, then loads pen core, at room temperature natural drying, obtains pencil blank;
4, with disinfection by ultraviolet light, dry, finally polish, polishing, colouring process can obtain required product.
