Abstract
A sealant with good weathering resistance is prepared from toluene, petroleum asphalt, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid, tetramethyl thiuram disulfide, magnesium oxide and a perfume; and the perfume is prepared from clove, Radix Aucklandiae, mint and wild chrysanthemum flower. The sealant has good weathering resistance, can adapt to violent change of ambient temperature between cold and hot, and has a good sealing effect; and the perfume is added, so the sealant obtained in the invention does not have the pungent smell of traditional glues and has good smell.
Description
Technical field
The present invention relates to a kind of seal gum, specifically a kind of seal gum of good weatherability.
Background technology
Seal gum be widely used in tank processed produce in the middle of, as a kind of packing matcrial, between entity or two objects gap be filled with a sealing, be mainly used in tank production technique processed encapsulation cover; But existing seal gum is all heavy chemicals, usually can give out irritating smell, very unpleasant.
Summary of the invention
The present invention aims to provide a kind of seal gum of good weatherability.
For realizing described object, the invention provides following technical scheme: a kind of seal gum of good weatherability, being made up of the raw material of following parts by weight: toluene 24-26 part; Petroleum pitch 23-25 part, dibutyl phthalate 0.9-1.1 part, zinc oxide 0.5-0.7 part, chloroprene rubber 48-52 part, stearic acid 0.4-0.6 part, tetramethyl-thiuram disulfide 0.05-0.07 part, magnesium oxide 1.9-2.1 part, perfume compound 10-13 part; Described perfume compound by 20% cloves distillate, the banksia rose distillate of 30%, the peppermint distillate of 15% and 35% Wild Chrysanthemum distillate make.
The preparation method of seal gum comprises following sequential steps:
(1) first petroleum pitch heating is dissolved and is in a liquid state, and slough moisture, removing impurity, and add the toluene of 50 % by weight, mix, obtained bituminous solution;
(2) chloroprene rubber, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid tetramethyl-thiuram disulfide are dropped into rubber mixing machine and carry out mixing together with magnesium oxide, obtain micelle;
(3) micelle is pressed into the thin slice of 1-2 mm thick;
(4) thin slice is cut into small shreds;
(5) small shreds is dropped in stirrer together with the toluene of remaining 50 % by weight, stir 3-5 hour, obtain chloroprene rubber solution;
(6) bituminous solution, chloroprene rubber solution perfume compound are put together, stir, obtained seal gum.
The preparation method of perfume compound comprises following sequential steps:
(1) get cloves, the banksia rose, peppermint and Wild Chrysanthemum to clean, and grind into powder;
(2) powder after pulverizing is used wet distillation, extractive distillation liquid respectively, and be separated with conical hopper;
(3) the cloves distillate obtained, banksia rose distillate, peppermint distillate and Wild Chrysanthemum distillate are uniformly mixed according to aforementioned proportion, can perfume compound be obtained.
Compared with prior art, the invention has the beneficial effects as follows: the seal gum of this good weatherability, be made up of toluene, petroleum pitch, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid, tetramethyl-thiuram disulfide and magnesium oxide, weather resistance is better, the acute variation of the envrionment temperature between h and c can be adapted to, good sealing effect; And with the addition of perfume compound in seal gum, do not have the irritating smell of traditional glue, smell is better.
