Disclosed is a novel process for producing a low carbon gas shielded welding wire. The novel process for producing the low carbon gas shielded welding wire includes following steps of (1) raw material selection, (2) surface treatment processes, (3) drawing process and (4) copper plating process, wherein the step (1) includes that as for steel wire rod composition, C is equal to 0.06-0.010%, Si is equal to 0.80-1.00%, Mn is equal to 1.40-1.60%, P or S is smaller than or equal to 0.020%, and Ca is smaller than or equal to 0.0015%; the step (2) includes an acid pickling process and a phosphating process, as for the acid pickling process, pickling solution proportion includes that prewash hydrochloric acid concentration is 5-10%, hydrochloric acid concentration for substrate washing is 15-20% and FeC12 is smaller than or equal to 300g / l, acid pickling time is 10-25minutes, washing is performed by high pressure water instantly after acid pickling, and as for the phosphating process, phosphating solution proportion includes that Ta total acidity is 50-110pt and Fa free acidity is 5-20pt, phosphating temperature is 70-80DEG C and phosphating time is 1-3 minutes. By means of the novel process for producing the low carbon gas shielded welding wire, a chemical adsorption film is formed on the surface of a steel wire rod, a thin phosphating film is formed on the surface of the steel wire rod by mid-temperature phosphating process and short phosphating time, adsorption of surface lubricating agents is more uniform and compact, the steel wire rod is directly drawn to form a finished product wire in an unannealed state after surface treatment, costs are reduced by 50-80 yuan / ton compared with those of common processes, the wire breaking rate is decreased by 70%, and the producing efficiency is increased by 40%.

The invention discloses a surface treating agent applicable to a toy plastic material and a preparation method thereof. The raw material formula of the surface treating agent consists of sodium laureth sulfate, laurinol disodium stearamido measulfosuccinate, lauramide propyl gydroxysulfobetaine, cocamide MEA, polyquaternium-7, ethylenediaminetetraacetic acid disodium salt, 1,3-dihydromethyl-5,5-dimethyl hydantion and dilute phosphoric acid. The surface treating agent can be applied to performing surface pretreatment on toy plastic materials such as acrylonitrile butadiene styrene (ABS) / polyvinyl chloride (PVC) and the like before coating. In the formula of the surface treating agent, environment-friendly materials are adopted completely, so the discharging quantity of volatile organic compounds (VOC) is close to 0. Compared with the traditional solvent type clean treating agent, the surface treating agent has better cleaning effect and better coating effect of the coating. The surfacetreating agent has a simple preparation method and low cost of the raw material formula, and can meet requirements of toy manufacturers and requirements of national low-carbon economy.

An attachment structure of a weight sensor for seat occupant detection, comprising: an insertion member (10, 101, 102) extending from a skin member of a seat portion to a in a groove on a cushion member of the seat portion; and at least one connecting member (9, 90, 91) connected to the insert member (10, 91) inside the groove 101, 102) of the second end portion. The opening portion (11, 110, 111, 23) is provided in the insertion member, and the weight sensor is inserted into the insertion member through the opening of the opening portion across the groove.
