Abstract
The invention discloses a kind of stainless steel weld joint back side novel protective agent; raw material including following composition: magnesium oxide, aluminium oxide, titanium dioxide, calcium oxide, sodium chloride, manganese oxide, silicon dioxide, bonding agent, surplus are acetone; in described raw material, shared by each composition, mass percent is: magnesium oxide 25～35%, aluminium oxide 2.5～7%, titanium dioxide 5～10%, calcium oxide 3.5～6.5%, sodium chloride 5～8%, manganese oxide 10～15%, silicon dioxide 6.5～10%, bonding agent 2～3.5%, and surplus is acetone.By the way, the one stainless steel weld joint back side of the present invention novel protective agent, it is possible to make back of weld non-oxidation, shapes good, and any surface finish has the resistance to pressure that good surface is anticorrosive and high simultaneously, is particularly suitable for the back-protective of rustless steel TIG weldering.
Description
Technical field
The present invention relates to welding protection material, particularly relate to a kind of stainless steel weld joint back side novel protective agent.
Background technology
Rustless steel has excellent corrosion-resistant, thermostability, non-oxidizability and good mechanical property and processing characteristics, is widely applied to the industry such as medical apparatus and instruments, petrochemical industry.Along with the expansion of rustless steel application, stainless steel welded market also quickly increases.
At present in stainless steel welded process; the main guard method adopted has the protection of back side nitrogen filled protection, ceramic substrate, mixed gas protected etc.; but in concrete operations; the welding protection in the above all inapplicable long stainless tube road of various guard methods; therefore, Stainless Steel Plant's pipeline welding protection requirement cannot also be met.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of stainless steel weld joint back side novel protective agent; back of weld non-oxidation can be made, shape good, any surface finish; there is the resistance to pressure that good surface is anticorrosive and high simultaneously, be particularly suitable for rustless steel TIG weldering and the back-protective of long pipeline welding.
For solving above-mentioned technical problem; the present invention provides a kind of stainless steel weld joint back side novel protective agent; raw material including following composition: magnesium oxide, aluminium oxide, titanium dioxide, calcium oxide, sodium chloride, manganese oxide, silicon dioxide, bonding agent, surplus are acetone; in described raw material, shared by each composition, mass percent is: magnesium oxide 25～35%, aluminium oxide 2.5～7%, titanium dioxide 5～10%, calcium oxide 3.5～6.5%, sodium chloride 5～8%, manganese oxide 10～15%, silicon dioxide 6.5～10%, bonding agent 2～3.5%, and surplus is acetone.
In one preferred embodiments of the present invention, in described raw material, shared by each composition, mass percent is: magnesium oxide 30～35%, aluminium oxide 5～7%, titanium dioxide 8～10%, calcium oxide 4.5～5.5%, sodium chloride 6.5～8%, manganese oxide 12～15%, silicon dioxide 8.5～10%, bonding agent 2.5～3.5%, and surplus is acetone.
In one preferred embodiments of the present invention, described bonding agent is mixed by acrylate, acrylic acid methyl ester., methyl methacrylate and ethyl 2-methacrylate, '-diphenylmethane diisocyanate.
