Abstract

The invention relates to a method for manufacturing a straw egg tray. In the method, straws are used as the raw material and are smashed and kneaded into threads, the threads are fermented and added with a waterproof adhesive, the adhesive and the threads are mixed and delivered to an egg tray molding machine to be molded, and the moulded product is dried to obtain the straw egg tray. The method saves a large number of resources and develops and makes use of the once wasted straw resource. Since the straw resource is rich and replaces waste paper and the raw material has low cost, the straw egg tray is much easier to be accepted by customers.

Description

The manufacture method of straw egg tray

Technical field

The present invention relates to a kind of manufacture method of egg holder, specifically a kind of manufacture method of straw egg tray.

Background technology

Egg holder (egg pallet) is the common in daily life a kind of apparatus of depositing egg of people, two kinds of egg holder that the egg holder of Shi Yonging in the market has (adopting the paper pulp manufacturing) made of paper and plastic egg holders, the use of above-mentioned two kinds of egg holders also exists many shortcoming and defect on certain degree, be in particular in, egg holder made of paper is owing to a large amount of paper pulp that utilizes, we know that paper is made by raw materials such as timber, so caused the waste of a lot of resources; Though and the use recycling rate of waterused height of plastics egg holder is not easy degraded after discarding, contaminated environment is in addition owing to the cost height, so also be difficult to by the consumer acceptance.So how can utilize reproducible waste resource, it is low to produce cost, free from environmental pollution, the egg holder that can be accepted by consumers in general again simultaneously is the problem of pendulum in face of people.

Stalk particularly has very big quantity as most of rural area of a kind of reproducible resource in China after autumn harvest, people have produced a lot of products in order to utilize stalk at present, as straw board, straw feed etc.But still having about percent stalk about seventy or eighty to be used to heating in the northern area of China cooks and incinerates.

Summary of the invention

The objective of the invention is to provide a kind of manufacturing process advantages of simple, cost low, can the reasonable use regenerated resources, the manufacture method of straw egg tray simultaneously free from environmental pollution again.

The object of the present invention is achieved like this, and the manufacture method of this straw egg tray is as follows:

A, stalk put into pulverize kneading machine to be processed into silk cotton-shaped;

B, the raw material that silk is cotton-shaped are put into fermentation vat, 50% the ratio of caustic-soda aqueous solution in raw material weight added in the fermentation vat, make the cotton-shaped raw material soaking of silk be fermented into thick (mud shape), about 72 hours of fermentation time, wherein caustic-soda aqueous solution is in water: the ratio of caustic soda=100: 3 is formulated.

C, in thick feed reservoir, add and be equivalent to the water of raw material weight 200%, 20% stone flour, 2% marine glue and mix;

D, mixed raw material in the c step is put into stirring pool stir, by pump the raw material that stirs is sent into moulding in the egg holder make-up machine, oven dry gets final product.

Marine glue in the described c step is to adopt rosin, caustic soda, paraffin, four kinds of feedstock production of aluminum sulfate to form, and the ratio of preparation is 10 parts of (ratio of weight and number) rosin, 2.5 parts in caustic soda, 1.5 parts in paraffin, 0.3 part in aluminum sulfate; The preparation method is: earlier with rosin, caustic soda, paraffin, water was put into vessel in heating 2 hours in right amount, made it be dissolved into pasty state, and adding aluminum sulfate stirs and makes marine glue in the pasty state raw material then.

Advantage of the present invention and good effect are as follows:

1, the present invention has saved a large amount of resources owing to adopt stalk as the raw material of producing the egg holder, makes also that simultaneously the stalk resource of once being discarded has obtained development and utilization.

2, because stalk resource is abundant, replace the cost of waste paper, raw material low, accepted by the consumer so straw egg tray is easier.

3, straw egg tray is a kind of material of very easy degraded, so be not easy to cause the pollution of environment after discarded.

The specific embodiment

A, stalk put into pulverize kneading machine (pulverizing kneading machine is the Northeast's crushed stalk kneading machine commonly used), be processed into the long silk of about 1-3mm cotton-shaped (is best with 1.5mm);

B, the raw material that the 100kg silk is cotton-shaped are put into fermentation vat, the 50kg caustic-soda aqueous solution is added in the fermentation vat, make the cotton-shaped raw material soaking fermentation of silk, the raw material after the fermentation becomes thick raw material (mud shape), about 72 hours of fermentation time, wherein caustic-soda aqueous solution is the ratio preparation in 100: 3;

C, in thick feed reservoir, add and be equivalent to the water of raw material weight 300kg, the stone flour of 30kg, the marine glue of 3kg;

Marine glue in the described c step is that rosin 10kg, caustic soda 2.5kg, paraffin 1.5kg, water were put into vessel in heating 2 hours in right amount, makes it be dissolved into pasty state, and adding aluminum sulfate 0.3kg stirs and makes marine glue 12kg in the pasty state raw material then.

Claims

1. the manufacture method of a straw egg tray, it is characterized in that: the manufacture method of this straw egg tray is as follows:

B, the raw material that silk is cotton-shaped are put into fermentation vat, 50% the ratio of caustic-soda aqueous solution in raw material weight added in the fermentation vat, it is thick that the cotton-shaped raw material soaking of silk is fermented into, about 72 hours of fermentation time, and wherein caustic-soda aqueous solution is in water: the ratio of caustic soda=100: 3 is formulated;

C, in thick feed reservoir, add and be equivalent to the water of raw material weight 200%, 20% stone flour, 2% marine glue;

2. the manufacture method of a kind of straw egg tray according to claim 1, it is characterized in that: described caustic-soda aqueous solution is in water: the ratio of caustic soda=100: 3 is formulated.

3. the manufacture method of a kind of straw egg tray according to claim 1, it is characterized in that: described marine glue is to adopt rosin, caustic soda, paraffin, four kinds of feedstock production of aluminum sulfate to form, and the ratio of preparation is 10 parts of rosin, 2.5 parts in caustic soda, 1.5 parts in paraffin, 0.3 part in aluminum sulfate; The preparation method is: earlier with rosin, caustic soda, paraffin, water was put into vessel in heating 2 hours in right amount, made it be dissolved into pasty state, and adding aluminum sulfate stirs and makes marine glue in the pasty state raw material then.
