Abstract
The present invention discloses a two-component room-temperature vulcanized silicone rubber and an individual packaging method thereof, which aims to solve the problem of poor adhesive force of RTV2 type room-temperature vulcanized silicone rubber in the prior art. The present invention is characterized in that water-soluble polymer solution containing hydroxy groups or water-soluble polymer emulsion containing hydroxy groups is added to the existing two-component room-temperature vulcanized silicone rubber as crosslinking agents. Therefore, the present invention is different from ordinary similar products, and can have bonding effects which can only be achieved by needing surface treatment for bonding objects when in use; simultaneously, the product also has the favorable characteristics of high curing speed, deep solidification, etc. inherently belonging to two-component room-temperature silicone rubber. The two-component room-temperature vulcanized silicone rubber is individually packaged by an extruding gun with double material pipes A and B, and has the advantages of convenient carrying and transportation, easy use, rapid solidification at room temperature and low cost.
Description
Technical field
The present invention relates to a kind of two-component room-temperature-vulcanized seal gum, also relate to the individual packaging method of this seal gum.
Background technology
Room temperature vulcanized silicone rubber is to be basic glue with hydroxy-end capped polydimethylsiloxane, forms through cooperating with linking agent, catalyzer, filler etc.
Room temperature vulcanized silicone rubber can be divided into one-pack type (hereinafter to be referred as the RTV1 type) and two (many) component types (being called for short the RTV2 type) by packaged form.
The RTV1 type is that basic glue, filler, linking agent, catalyzer etc. are mixed under anhydrous condition, seals in the containers such as pipe or cylinder of packing into to sell, and extrudes and can use.The shortcoming of this class silicon rubber sealant is that the completely solidified time is long, and generally is difficult to completely solidified during greater than 6 millimeters when cured layer thickness, can only adopt the method construction of layering coating.
The RTV2 type is meant basic glue and linking agent, catalyzer etc. is separated packing, they is mixed use before use.But its outstanding weakness is that adhesiveproperties is relatively poor.
Document " adhesiveproperties of condensed room temperature vulcanized silicone rubber and bonding mechanism analysis; " rubber industry " 1998; 45 (11): 663-665 " discloses Su Zhengtao, Shen Yusheng and has analyzed and researched at the adhesiveproperties of RTV2 type silicon rubber on multiple base material, the cementability of discovering RTV2 type silicon rubber is very poor, shearing resistance＜0.50Mpa.
At present, RTV1 type silicon rubber adopts single packing substantially, and RTV2 type silicon rubber adopts bi-component package or polycomponent packing substantially.
Document " nylon-6 is extruded in twin screw reaction; " plastics science and technology " 1997; (6): 40-42 " discloses people such as Shao Jiamin, summer Zhejiang peace and has adopted reaction to extrude novel process caprolactam monomer to be carried out twin screw reaction synthetic high polymer nylon-6 and nylon-6 goods, realize the integration synthesis process process of twin screw extruder from monomer-superpolymer-article.The injecting type packing method of epoxy glue etc. is also arranged on the market, but do not have the extra package technology of silicone based product.
Summary of the invention
In order to overcome the deficiency of prior art RTV2 type room temperature vulcanized silicone rubber cementability difference, the invention provides the individual packaging method of a kind of two-component room-temperature-vulcanized silicone rubber and this silicon rubber, as linking agent, carry out single the packing with the water-soluble polymer of hydroxyl or macromolecule emulsion with the rifle of extruding that has A, the extra quality pipe of B.This silicon rubber sealant can the deep layer fast setting, and the gluing ability of connecing is strong.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two-component room-temperature-vulcanized silicone rubber, contain 1～13.6% hydroxyl water-soluble polymer solution or macromolecule emulsion, 0～3.4% dibutyl tin laurate, 55.9～68% hydroxy-end capped silicon rubber basis material, 13.6～25.3% gas-phase silica, 0～10.8% titanium dioxide, 0～9.55% silicon class linking agent and 0～0.05% organic titanium.
Described hydroxy-end capped silicon rubber basis material is methyl silicone rubber, phenyl siloxane rubber, methyl phenyl silicone rubber, or its mixture.
The individual packaging method of the above-mentioned two-component room-temperature-vulcanized silicone rubber of a kind of claim 1 is characterized in that, comprises the steps:
1) with 1～13.6% the hydroxyl water-soluble polymer solution or the dibutyl tin laurate of macromolecule emulsion and 0～3.4%, at room temperature mix, mixture is the B component;
2) 55.9～68% hydroxy-end capped silicon rubber basis is expected, 13.6～25.3% gas-phase silica, 0～10.8% titanium dioxide, 0～9.55% silicon class linking agent and 0～0.05% organic titanium at room temperature mix, and mixture is the A component;
3) be A, the B pipe that 3～6/1～2 injection screw rods are extruded rifle with above-mentioned two kinds of mixtures by A component/B component.
The invention has the beneficial effects as follows: because the water-soluble polymer of employing hydroxyl or macromolecule emulsion can make the silicon rubber deep layer vulcanization as linking agent, the gluing ability of connecing improves, and shearing resistance is brought up to more than the 1.2Mpa by the 0.50Mpa of prior art; Owing to adopt the two-pack batching, be easy to adjust so have when use, self-vulcanizing speed is fast, but 5～15min completely solidified, cost is lower; Owing to adopt the single-component package method to pack, transportation and use are easy to carry.
The present invention is further described below in conjunction with embodiment.
