Description

A kind of manufacturing technique of fire-retarded corrugated paper plate

Technical field

The present invention relates to a kind of manufacturing technique of corrugated board, particularly relate to a kind of manufacturing technique of fire-retarded corrugated paper plate, belong to field of packaging material.

Background technology

Corrugated board is the composite construction of a multilayer, and it is minimum is made up of one deck corrugated intermediate layer and a layer paperboard.Corrugated board has higher mechanical strength, can absorb the collision in freight handling process and fall to fall, mainly for the manufacture of the external packing of the sandwich and delicate articles of carton, carton.Corrugated board temperature influence is little, and shading performance is good, general also less by humidity effect, but fire protecting performance is bad, meet high temperature or naked light inflammable.

A few days ago, the number of corrugated board production manufacturer of China constantly increases, and its production technology have also been obtained rapid progress.But, as the disappearance of corrugated board fire resistance in its use procedure that packaging material use, its article packed can be caused in storage and transport process to have disaster hidden-trouble, even can bring certain economic loss.

Summary of the invention

For the demand, the invention provides a kind of manufacturing technique of fire-retarded corrugated paper plate, this manufacturing technique procedure arrangement is reasonable, obtained corrugated board interlayer bond strength is high, stable performance, and possess fire-retardant fireproof, the advantage such as safe and reliable, significant role is played to the security aspect improving connection with wrapping of piece, and fire-retardant packaging material universal on have market prospects widely.

To achieve these goals, the technical solution used in the present invention is as follows:

A manufacturing technique for fire-retarded corrugated paper plate, is characterized in that, this manufacturing technique comprises the steps:

1) prepare upper epidermis and layer, 2) manufacture in the middle of corrugated layer, 3) adhering and solidifying, 4) cut, 5) fire retardant infiltrate and dry.

Described step 1) in, the manufacturing process of upper epidermis and layer comprises: select standby raw material, prepare paper pulp, copy paper and arrangement etc., obtained upper epidermis and layer thickness are about 1.25-1.29mm.

Described step 2) in, middle corrugated layer is that the height obtained by fluting medium is about 2.5mm, the corrugated layer of moisture 7.5%-7.8%.

Described step 3) in, the bonding between upper epidermis, intermediate layer, layer adopts uncooked amylum binding agent, and the coating thickness of binding agent controls at 0.2-0.25mm, and the bonding speed of a motor vehicle controls at 0.1-0.12m/s; Solidification temperature controls at about 55 DEG C, and the time is about 30-35 minute.

Described step 4) in, after adhering and solidifying completes, utilization cuts lathe and Paperboard cutting is become preliminary dimension and shape.

Described step 5) in, fire retardant comprises ammonium phosphate, sulfamic acid, sulfamic acid ammonia, phosphoguanidine or Guanidine Sulfamate 99.

Detailed description of the invention

Below in conjunction with embodiment, technical scheme of the present invention is described.

Embodiment one

The concrete preparation process of the fire-retarded corrugated paper plate that the present invention mentions is as follows:

1) prepare upper epidermis and layer, the preparation section of upper epidermis and layer comprises: select standby raw material, prepare paper pulp, copy paper and Final finishing etc.;

The preparation process of paper pulp is as follows: first, pours slurry into agitator, and add the clear water of 7.5 times of slurry volume, uniform stirring, agitator barrel temperature controls at 25 DEG C-38 DEG C; Then, add filler, sizing material and chemical assistant successively, be about 12 minutes interval time, keep agitator temperature and Keep agitation; Then, agitator temperature increase to 35 DEG C-48 DEG C, fully stirs; Finally, pour quantitative clear water into, fully stir, agitator temperature maintains about 30 DEG C, and obtained pulp density is about 0.8%-0.85%;

Copy paper operates on paper machine carries out, and first, uses the moisture in copper mesh filtering paper pulp, obtained l Water Paper;

Then, adopt the excessive moisture that pressure roller is squeezed out in l Water Paper further, obtained half-dried paper; Finally, sent in drying equipment by half-dried paper and carry out drying and processing, obtained semi-finished product, half-finished water content control is at 5%-6%;

Final finishing comprises operations such as half-finished press polish, rewinding, cut papers;

The upper epidermis thickness obtained by above-mentioned technique is about 1.25mm, and layer thickness is about 1.29mm;

2) corrugated layer in the middle of preparation, middle corrugated layer raw material can select secondary stock or useless cloth slurry, and first, adopt tradition paper technique processed to prepare fluting medium, THICKNESS CONTROL is at 1.3-1.4mm; Then, under high temperature, condition of high voltage, by the clamping action of upper and lower Corrugator roller, fluting medium is bent to corrugated shape; Obtained middle corrugated layer height is about 2.5mm, and water content control is at 7.5%-7.8%;

3) adhering and solidifying, the bonding of upper epidermis, middle corrugated layer and layer adopts starch adesive, and the coating thickness of binding agent controls at about 0.25mm, and the bonding speed of a motor vehicle controls at about 0.12m/s; Solidification temperature controls at about 55 DEG C, and the time is about 30-35 minute;

4) cut, after adhering and solidifying completes, cut into preliminary dimension and shape;

5) fire retardant infiltrates and dries, and the cardboard after cutting is put into ammonium phosphate, sulfamic acid, sulfamic acid ammonia, phosphoguanidine or Guanidine Sulfamate 99 solution and infiltrates and after drying, obtain fire-retarded corrugated paper plate.

Above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although above-described embodiment is to invention has been detailed description, the person skilled of this area is to be understood that: can modify to the present invention or replace on an equal basis, but any amendment not departing from spirit and scope of the invention all should be encompassed in right of the present invention with local replacement.
