Abstract
The to-be solved technical problem of the invention is to provide a production technology for a neutral transparent silicone sealant. The production technology comprises the following steps: first step, preparing rubber in a cylinder; second step, performing static flocculation mixing, and third step, subpackaging. The first step of rubber preparation in the cylinder, 107 silicone rubber and a cross-linking agent methyltris(methylethylketoximino)silane in the rubber preparation cylinder are reacted relatively slowly, so that before the rubber preparation cylinder is transported to a static mixer, no particle crusting is generated and the product appearance is not influenced, and the product appearance quality is effectively improved. According to the second step of static mixer flocculation mixing and the third step of subpackaging, vacuum pipe static mixing is employed, rubber is not contacted with, and therefore bubbles generated during rubber preparation are substantially reduced, the appearance quality of the sealant finished product is effectively improved, and also the changing frequency of a filter screen is reduced. The production technology is smooth and reasonable, labor intensity is effectively reduced, and the subpackaging efficiency and the production efficiency of the whole production line are improved.

Technical field
The present invention relates to a kind of production technique of silicone sealant, specifically refer to a kind of production technique of neutral transparent silicone seal gum.
Background technology
At present, the production technique of domestic neutral transparent silicone seal gum is first in glue cylinder, to complete glue, glue cylinder is being moved to the packing of carrying out seal gum on portioning machine.The main drawback of the method is: point seal gum visual appearance taking on is relatively poor, for the visual appearance that improves seal gum needs constantly to change filtering net in the process of packing.Cause seal gum ingress of air and change filtering net, thereby produce aeration product appearance.And artificial mechanism labour intensity is large in existing production technique, loaded down with trivial details, the increase labour cost of working, production efficiency is low.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is that a kind of production technique of neutral transparent silicone seal gum is provided, can effectively enhance productivity, labour intensity is little, reduces the number of times of changing filtering net, effectively improves product appearance quality.
For solving the problems of the technologies described above, the technical solution used in the present invention is that a kind of production technique of neutral transparent silicone seal gum, comprises the steps:
The first step, glue in cylinder:
In glue cylinder, according to quality proportioning, add 45-50 part 107 silicon rubber, 4-6 part linking agent methyl tributanoximo silane, and 20-30 part 3# alkane oil, be evacuated to-0.09mpa, stirs 20min; Add again 12-18 part gas-phase silica, stir;
Second step, static wadding stream mixes:
Glue cylinder is moved on static machine, according to quality proportioning, added 3-8 part linking agent vinyl tributyl ketoximyl silane, 2-4 part coupling agent KH550, KH560,0.1-0.3 part catalyzer dibutyl tin laurate, mixes through static machine wadding stream;
The 3rd step, packing:
Through vacuum-sealing pipeline static mixing, be packed as finished product with filter screen.
The production technique of above-mentioned a kind of neutral transparent silicone seal gum, comprises the steps:
The first step, glue in cylinder:
In glue cylinder, according to quality proportioning, add 46.8 part of 107 silicon rubber, 5 parts of linking agent methyl tributanoximo silanes, and 25 parts of 3# alkane oils, be evacuated to-0.09mpa, stirs 20min; Add again 15 parts of gas-phase silicas, stir;
Second step, static wadding stream mixes:
Glue cylinder is moved on static machine, according to quality proportioning, added 5 parts of linking agent vinyl tributyl ketoximyl silanes, 3 parts of coupling agent KH550, KH560,0.2 part of catalyzer dibutyl tin laurate, mixes through static machine wadding stream;
The 3rd step, packing:
Through vacuum-sealing pipeline static mixing, be packed as finished product with filter screen.
Tool of the present invention has the following advantages and useful technique effect:
1, in the first step cylinder of the present invention when glue, 107 silicon rubber in glue cylinder with linking agent methyl tributanoximo silane reacting phase to slowly, before glue cylinder is moved to static machine, can not produce particle skinning and affect product appearance, can effectively improve product appearance quality.
2, the present invention mixes and the 3rd step packing through the static machine wadding of second step stream, process be vacuum pipe static mixing, can ingress of air, therefore can greatly reduce to produce bubble in glue process, effectively improve the visual appearance of seal gum finished product, reduce the replacing number of times of filtering net simultaneously.
3, production technique of the present invention is rationally smooth, effectively reduces hand labor intensity, improves the production efficiency of packing efficiency and whole production line.
