Abstract
The invention relates to a method for preparing a composite material clad bolt, in particular to a method for preparing a high-temperature-resistant insulating composite material clad bolt. The method for preparing the high-temperature-resistant insulating composite material clad bolt comprises the following steps of: performing stain removing and napping on a cylindrical part of an iron bolt, adding zinc stearate, aluminum powder and magnesia powder into phenolic resin, adding a curing agent to prepare resin paste, coating the resin paste on the surface of glass fiber cloth, and cutting a composite material plate into a plate of specified width and length after the resin is gelled; and coating a composite material layer outside the iron bolt, embedding the iron bolt coated with a composite material into a mold for press molding, cooling to room temperature, and opening the mold to obtain the high-temperature-resistant insulating composite material clad bolt. Due to the adoption of the method, the defect of long producing and storing periods existing in the production of the conventional composite material plate is overcome, the composite material insulating layer and the iron bolt are combined more firmly without slippage, and relevant accidents can be effectively and completely eradicated.
Description
Technical field
The present invention relates to the preparation method that a kind of composite material coats bolt, particularly relate to the preparation method that a kind of high-temperature insulation composite material coats bolt.
Background technique
The high-temperature insulation bolt is to be used in a kind of device that guarantees absolute insulation on the electrolytic bath riser bus bar.Originally being installed on the riser bus bar is iron bolt, puts a spaghetti again and reach insulation effect outside iron bolt.Owing to have the gap between iron bolt and the spaghetti, in manipulating process, very easily cause producing slippage between sleeve pipe and the iron bolt, cause misplacing between spaghetti and iron bolt, thereby make iron bolt middle part branch expose outside spaghetti.At this moment, because electric current [strength is big, magnetic field is high, iron bolt very easily is adsorbed on the bus, and dismounting inconvenience, and guiding discharge big fire cause serious accident.So combining between spaghetti and iron bolt is a very important part in the high-temperature insulation bolt.Therefore, invent a kind of preparation method make combine closely between the spaghetti of high-temperature insulation bolt and iron bolt just very necessary.
Summary of the invention
The objective of the invention is to provide a kind of preparation method of high-temperature insulation bolt at the demand that should combine closely between above-mentioned high-temperature insulation sleeve pipe and iron bolt.
The preparation method that a kind of high-temperature insulation composite material coats bolt is as follows:
(1) takes by weighing following each component by weight: 80 parts in phenolic resin, NL curing agent 5-10 part, zine stearate 3-4 part, aluminium powder 40-60 part, magnesia powder 1-2 part, glass cloth 20-35 part.
(2) get 1 iron bolt, with fine sandpaper with iron bolt column part decontamination plucking.
(3) moulding process of sticking with paste glass fibre reinforced plastics according to hand utilizes the component produced with combination sheet material of step (1), promptly earlier zine stearate, aluminium powder, magnesia powder are joined in the phenolic resin by proportioning, after stirring, add the NL curing agent, stir evenly and make resin paste, the surface that again this resin paste is coated in glass cloth utilizes pressure roller that the thickness of composite board is rolled into 2-3mm, when treating that resin reaches gel state in the above-mentioned sheet material, the length of the column part of the iron bolt of being got according to step (2) is cut into composite board the width of appointment; According to the girth of iron bolt column part, composite board is cut into the length of appointment.
(4) adopt manual method, the composite board that sanction is good is wrapped in one week of appearance of iron bolt column part, the width direction of composite board is consistent with the length direction of iron bolt, by this step, makes the column part of iron bolt be wrapped up fully by composite material.
(5) as required, desirable more composite board adopts and the identical method of step (4), 1-3 layer composite layer on the iron bolt coated outside, but the overlap joint mouth of every layer of composite material after wrapping up staggers each other.
(6) iron bolt that will wrap up composite material is implanted in the half-terete die cavity of half module under the mould that has been preheating to 130-140 ℃, and the upper mold section that closes, upper mold section have the semi-cylindrical die cavity equally.
(7) mould is moved in the press be pressed molding pressure 750-850t, clamp time 7-9min..
(8) compacting finishes, treat that mould is cooled to room temperature gradually together with product after, die sinking promptly get high-temperature insulation composite material coating bolt.
The said iron bolt of the present invention is commercially available iron bolt, and two is a worm structure, and the centre is a solid cylinder, and worm structure is used for being complementary with nut, so that fixing bolt; The length of middle solid cylinder is consistent with the width of electrolytic bath riser bus bar.
The said phenolic resin of the present invention is 2124 type phenolic resin.
The said aluminium powder particle diameter of the present invention is 100 orders or 120 orders.
The said magnesia powder particle diameter of the present invention is 180 orders or 220 orders.
The said glass cloth of the present invention is substance 27g/m
2Or 52g/m
2In a kind of.
The innovation part of a kind of high-temperature insulation bolt that the present invention obtains is: elder generation is according to the prescription of high-temperature insulation composite material, adopt hand formulating method forming composite sheet material, adopt manual method that it is wrapped in the iron bolt outer surface during the firm gel of resin in composite board, the high pressure by press tightly pastes clothes on iron bolt with composite board then.When having reduced conventional production composite board, this kind method produces and defective that storage cycle is long, simultaneously, owing to be covered by on the iron bolt when resin has just begun gel in the composite material, under the acting in conjunction of pressure and heating, the further curing reaction of resin, and shrink, thereby can tightly wrap up and firmly be combined on the iron bolt.With only comparing by manual coating of routine, combining between composite material isolation layer and the iron bolt is more firm; And compare with the high-temperature insulation bolt that iron bolt adds sleeve pipe, there is not slippage between high-temperature insulation composite layer and the iron bolt in a kind of high-temperature insulation bolt of the present invention's preparation, can effectively stop the generation of relevant accident.
