Abstract
The present invention relates a prodn. method of hot-melt glue. The invented glue possesses the advantages of low application temp. (170-190 deg.C), proper melt viscosity, good toughness, excellent weather ability and medium-resistant property. It not only is suitable for mechanzation of sealing centrum drug column, and automation of spray-coating seal but also is suitable for use in bookbinding and quick sealing of case.
Description
The present invention relates to a kind of method for making of composition of raw materials and glue of hot melt adhesive.It specifically is exactly the production method that explosive-source explosive post seals hot melt adhesive composition of raw materials and hot melt adhesive.
Explosive-source explosive post is a kind of explosive provides focus for petroleum geology exploration special bullet that loads in plastics (being generally HOPE) housing.Sealing process is one of critical process of producing explosive-source explosive post, and mouth-sealing method commonly used has heat seal, pitch prill pouring method and hot melt adhesive Sealing Method etc.Hot melt adhesive commonly used generally is with the moulding seal gum of other industry use etc.This glue melt viscosity is big when sealing, and uses inconvenience, though or through adding the wax allotment is mobile to increase the easy embrittlement of sizing material; The weathering resistance of sizing material is undesirable, and product is stored easily to produce after for some time and come unstuck or split the glue phenomenon, causes the product water inlet when using of going into the well, and occurs miss-firing.Heat seal and pitch pouring are sealed because security and endurance issues are not well solved, and progressively are eliminated.
For overcoming above-mentioned deficiency,, the invention provides a kind of composition of raw materials of hot melt adhesive of explosive-source explosive post special-purpose sealing and the production method of glue in conjunction with the production and the handling characteristics of explosive-source explosive post.
A kind of explosive-source explosive post seals hot melt adhesive, it is characterized in that: the composition of raw materials of this glue comprising than (weight part):
0 part of a, ethylene-vinyl acetate copolymer (EVA) I5-5,
Vinyl acetate content (VA) is: 21-45%,
Melting index (MI) is: 51-250g/10min;
B, ethylene-vinyl acetate copolymer (EVA) II4-10 part,
Vinyl acetate content (VA) is 2-20%,
Melting index (MI) is: 20-50g/10min;
C, staybelite glyceride 20-45 part; Softening temperature is: 70-110 ℃;
D, paraffin 10-30 part, fusing point is 50-70 ℃;
E, macromolecule synthesising wax 3-20 part, fusing point is 100-110 ℃;
F, styrene-isoprene block copolymer (SIS) 5-20 part,
G, oxidation inhibitor 0.1-1 part,
H, talcum powder 6-15 part.
The staybelite glyceride can be substituted by rosin glyceride or petroleum resin.
A kind of explosive-source explosive post seals the hot melt adhesive composition of raw materials, it is characterized in that: the vinylbenzene and the isoprene ratio of styrene-isoprene block copolymer (SIS) are: 12-20: 88-80.
Production method: the rosin fat that measures and wax class and oxidation inhibitor are added in the container of temperature controllable, heating makes each component softening, be warming up to 170-190 ℃ again, stir, add ethylene-vinyl acetate copolymer (EVA) and vinylbenzene-different diene block copolymer (SIS) of defending, be stirred to each component consolute uniform decrease in temperature to 140-160 ℃; Add talcum powder then, be cooled to 90-110 ℃ and import twin screw extruder, the granulation cooling promptly gets this product.
The hot melt adhesive that the present invention produces is compared with existing hot melt adhesive has use temperature low (170-190 ℃), and melt viscosity is moderate, good toughness, the characteristics that weathering resistance and resistance to medium are good.It not only is suitable for explosive-source explosive post mechanize, automatic spraying seals, but also is applicable to the unsewn binding of books, fields such as quick joint sealing.
Embodiment: example 1: with 28 parts of staybelite glyceride, 22 parts in paraffin, 3 parts of macromolecule synthesising wax, oxidation inhibitor (1010) is a to add in the temperature controllable container, the heating each component is softening, be warming up to 170 ℃ again, after stirring, add EVAI28 part, EVAII4 part and SIS5 part, be stirred to the each component consolute and be cooled to 140 ℃ after evenly, add 9 parts of talcum powder, be cooled to 90 ℃ again and import twin screw extruder granulation cooling and promptly get this product.
Example 2; With 25 parts of staybelite glyceride, 25 parts in paraffin, 5 parts of macromolecule synthesising wax, oxidation inhibitor (1010) is a to add in the temperature controllable container, and the heating each component is softening, be warming up to 190 ℃ again, after stirring, add EVAI25 part, EVAII5 part and SIS6 part, be stirred to the each component consolute and be cooled to 160 ℃ after evenly and add 8 parts of talcum powder, be cooled to 110 ℃ again and import twin screw extruder granulation cooling and promptly get this product.
The foregoing description products obtained therefrom is listed as following table:
| Embodiment | Ring and ball softening point (℃) | Melting viscosity (170 ℃ of MPas) | Shearing resistance (250 ℃ of MPa) | Outward appearance |
| ????1 | ????72.5 | ????2800 | ????3.32 | Faint yellow saccharoid does not have mechanical impurity |
| ????2 | ????74.0 | ????3000 | ????3.4 | Faint yellow saccharoid does not have mechanical impurity |
