Description of drawings
Fig. 1 is the preparing method's of an extraordinary sealing wax of the present invention process flow sheet.
Embodiment
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is done explanation further.
In the embodiments of the invention, inspissated wax is selected No. 64 paraffin wax fully refineds, and the HMP Microcrystalline Wax is selected No. 80 refining Microcrystalline Waxes, and beeswax is selected cera alba, and polyethylene wax is selected the WE-3 polyethylene wax, and tackifier are selected LAN603 type tackifier.
The invention provides a kind of extraordinary sealing wax, sealing wax comprises following raw materials in percentage by weight:
Inspissated wax 73-80.5%;
HMP Microcrystalline Wax 10-14.5%;
Beeswax 4-6%;
Polyethylene wax 5-5.5%;
Tackifier 0.5-1%.
The preparation method of extraordinary sealing wax of the present invention comprises following concrete steps (as shown in Figure 1):
Step 1 (promptly first section) is in harmonious proportion paraffin and polyethylene wax in the still first in the above-mentioned raw materials ratio, stirring heating, and at 130 ℃, stirring velocity is 70 rev/mins, mixes 1h, obtains first section compound;
Step 2 (promptly second section), with Microcrystalline Wax and beeswax stirring heating in the second mediation still, at 100 ℃, stirring velocity is 50 rev/mins, mixes 0.5h, obtains second section compound in the above-mentioned raw materials ratio;
Step 3 (promptly the 3rd section) joins the 3rd with first section compound of step 1 gained with the resulting second section compound of step 2 and is in harmonious proportion stirring heating in the still, and at 120 ℃, stirring velocity is 60-70 rev/min, mixes 1h, obtains the 3rd section compound;
Step 4 (promptly the 4th section), the 3rd section compound with step 3 gained joins stirring heating in the 4th mediation still with tackifier again, at 100 ℃; Stirring velocity is 40-50 rev/min, mixes 0.5h, naturally cooling, moulding; Packing obtains extraordinary sealing wax finished product of the present invention.
The present invention selects segmentation to be in harmonious proportion, and every section is adopted different processing temperature and stirring velocity.As shown in table 2, for identical at raw material, under proportioning the same terms, the performance of products of the one-part form of four-part form technology of the present invention and prior art, two-section type, syllogic prepared gained relatively.Wherein, prescription is (by weight count) as follows: 76 parts of No. 64 paraffin wax fully refineds, 12 parts of No. 80 refining Microcrystalline Waxes, 6 parts of cera albas, 5 parts of WE-3 polyethylene waxs, 1 part of LAN603 type tackifier.International U.S. ASTM testing method is adopted in the test of performance index.
Table 2: identical at raw material, under proportioning the same terms, different feeding mode embodiment relatively
One section processing is to become mixed solution to heating and stirring in mediation still of all batching addings, and test shows that the process-cycle is long, and yield low (hardness reduction) causes power consumption of polymer processing high, and quality does not reach index request, and is as shown in table 2.And, adopting two sections, three sections working methods, its outcome quality index does not reach requirement yet.Adopt four sections working methods of the present invention, the quality requirement that can touch the mark, and more easy to control in the index request scope, repeatedly TE shows that quality index is all in the standard-required interval; And with short production cycle, easy to operate, yield is high.
Find that through test temperature of reaction, stirring velocity, mixing time under the material proportion same case, also exert an influence to quality index.In same section (like step 4, the 4th section) processing, temperature of reaction, stirring velocity are influential to oleaginousness: when adding temperature greater than 100 ℃, or stirring velocity is during greater than 50r/min, and oleaginousness all can raise, and influences quality index; When stirring velocity was lower than 40r/min, mixed solution was insufficient warm, also influenced quality (under same temperature).Through evidence, the 4th section temperature of heating is controlled at 100 ℃ of optimums, and it is comparatively suitable that mixing speed is controlled at 40-50r/min, and reaction time is at 0.5h.
Further, in same section (like step 4, the 4th section) processing; Under the identical situation of warm-up time, temperature of reaction, stirring velocity are influential to fusing point: under identical warm-up time condition, rotating speed is at 40r/min; Temperature fusing point before 100 ℃ is the rising state, and as stirring velocity＞50r/min, the temperature of heating is more than 110 ℃ the time; Fusing point is on a declining curve, produces the variation of melting flex point.It is thus clear that stirring velocity is more satisfactory when 40-50r/min; Under this rotating speed state, the temperature of heating is controlled at 100 ℃ and is advisable, and at this moment, the viscosity of tackifier is better, and temperature is higher than 100 ℃, and viscosity can reduce.
Adopt above-mentioned same method; Through verification experimental verification: first ideal mixing period is 1h; Stirring velocity is 70 rev/mins, and Heating temperature is 130 ℃, because the fusing point of paraffin and polyethylene wax is higher; Could be fused fully under this temperature condition, paraffin and polyethylene wax mutual solubility were bad when temperature was lower than 130 ℃; Second ideal mixing period is 0.5h, and stirring velocity is 50 rev/mins, and Heating temperature is 100 ℃, because when temperature when higher (as up to 130 ℃), the acid in the beeswax can be destroyed, thereby causes the moistureproofness of product to reduce; The 3rd ideal mixing period is 1h, and stirring velocity is 60-70 rev/min, and Heating temperature is 120 ℃.
In the embodiments of the invention, different materials is according to the different processing sections of forming of its performance, and purpose is to shorten to add the duration, the material recurring structure is changed guarantee that its performance characteristic is constant.
Embodiment 2-3 and Comparative Examples 4-8
Adopt four sections complete processings of the present invention, feeding intake in the ratio of table 3 makes sealing wax, and carries out performance test.
Table 3: the situation that feeds intake and the performance test of embodiment 2-3 and Comparative Examples 4-8
In some embodiments of the invention; Show that the addition of polyethylene wax and the fusing point of sealing wax product have certain relation: when addition during at 1-3%; Fusing point rises very fast, when add-on during at 3-4% fusing point raise more steady, when addition during at 5-5.5% fusing point can reach requirement.But fusing point is on a declining curve when addition surpasses 5.5%.
In some embodiments of the invention, experiment shows: should select low-molecular-weight polyethylene wax, exempt the be full of cracks of wax under low temperature environment.When addition during at 5-5.5% fusing point can touch the mark, and other performance index are not exerted an influence.
Through measuring, the sealing wax The comprehensive performance index of gained of the present invention is superior to 602 special wax.Also can be used in fiber optic cables communication and the oil pipeline sealing material.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
