Description

The preparation method of the pen cap of double layer hardness

Technical field

The present invention relates to stationery and make the field, particularly the pen cap is made the field, specifically is meant a kind of preparation method of the pen cap of double layer hardness.

Background technology

In the modern life, pen is indispensable stationery, but in the prior art, the pen cap on the common penholder has only single hardness, when the user uses for a long time, cause the fatigue and the tenderness of hand easily, influenced people's normal use, especially for students in middle and primary schools, be in the age of growing, bone and joint be zoon not as yet all, uses the pen of single hardness for a long time, can cause the damage that to repair to the finger that holds a pen, even make fingers deformed.

In addition, for present some article commonly used, for example: racket, golf clubs, shoe-pad, hand tools and other are held product, also have same problem, have brought very big inconvenience with regard to the life to people like this.

Summary of the invention

The objective of the invention is to have overcome above-mentioned shortcoming of the prior art, provide a kind of and have double layer hardness, meet principle of human engineering, use comfortable, processing step simple, cost of material is lower, it is durable to stablize, the applicable surface preparation method of the pen cap of double layer hardness comparatively widely.

In order to realize above-mentioned purpose, the preparation method of the pen cap of double layer hardness of the present invention is as follows:

The preparation method of the pen cap of this double layer hardness comprises the manufacturing process of the outer pen cap and the manufacturing process of the internal layer pen cap, and its main feature is that the manufacturing process of the described outer pen cap may further comprise the steps:

(1) virgin rubber is mixing: the silica gel raw material is carried out mixing, carry out the allotment of respective color and hardness number;

(2) raw material cutting: heavy according to required material, the raw material after mixing is cut;

(3) discharge operation: the raw material after will cutting is inserted in the corresponding mould;

(4) forming operation: is that 150 ℃～200 ℃, pressure are 80 kg/cm with the raw material in the mould in temperature ²～150 kg/cm ²Environment in placed 200 seconds～300 seconds;

(5) stripping operation: the finished product after the moulding is taken out from mould;

(6) secondary adds sulphur: finished product is carried out the secondary sulfur adding treatment, thereby finish the manufacturing process of the outer pen cap;

The manufacturing process of the described internal layer pen cap may further comprise the steps:

(1) raw material is mixing: carry out silica gel raw material and silicone oil mixing;

(2) discharge operation: in the above-mentioned outer pen cap of making, insert mould, a certain amount of raw material after mixing is clamp-oned in the space between the above-mentioned outer pen cap and the mould;

(3) forming operation: the raw material that will clamp-on the outer pen cap places the room temperature environment compacted under;

(4) stripping operation: the finished product after the moulding is taken out from mould, thereby finish the manufacturing process of the internal layer pen cap, obtain the pen cap of complete double layer hardness.

The forming operation of the outer pen cap manufacturing process of the preparation method of the pen cap of this double layer hardness is:

Is that 175 ℃, pressure are 115 kg/cm with the raw material in the mould in temperature ²Environment in placed 250 seconds.

Adopted the preparation method of the pen cap of the double layer hardness of this invention, because adopting silica gel is raw material, with low cost, have the outer pen cap and the internal layer pen cap two cover production process successively simultaneously, make the pen cap of making have double-decker, and has different hardness, the outer pen cap is because raw material itself, HTHP moulding process and secondary add sulphur technology, make and itself have toughness and certain rigidity preferably, wearability, and internal layer is owing to be mixed with silicone oil in the raw material, and employing formed at normal temp, itself do not do and add the sulphur cure process, thereby kept the abundant elasticity of colloidal silica itself, made the whole pen cap have very comfort feel, met the ergonomics standard; Simultaneously, the inside and outside two-layer combination of the pen cap gets very tight, stablize durable, applicable surface is comparatively extensive, not only is suitable for pen stationery, and be applicable to that racket, golf clubs, shoe-pad, hand tools and other hold the damping part of product, bring great convenience for people's life.
