As shown in figure 1, the component of bolt 100 includes bolt 100, nut 130 and insert sheet for positioning 300, bolt 100 includes bolt
110 are provided with the installing hole 210 passed through for screw rod 120 with screw rod 120, connection strap and two arbors, and bolt head 110 is provided with
Circumferential uniform locating slot 111, is provided with one group of radial slot 220 docked with locating slot 111 at the installing hole 210 of connection strap, and one
Individual locating slot 111 and the radial slot 220 docked with the locating slot 111 are collectively forming for one insert sheet for positioning 300 of placement
Grafting space, nut 130 is threadedly connected on screw rod 120, and connection strap and two arbors are held on bolt head 110 and nut 130
Between.The l-shaped member that the insert sheet for positioning 300 is made up of vertical bar 320 and transverse bar 310.
The quantity of locating slot and insert sheet for positioning is eight in the present embodiment, naturally it is also possible to according to specific needs, improves
For three.
The bolt assembly surface is coated with alkyd resin, and the alkyd resin is by the component preparation of following mass fraction
Into：Phthalic anhydride 200g, cis-butenedioic anhydride 140g, neopentyl glycol 150g, tetramethylolmethane 20g.Its preparation process is by phthalic anhydride 200g, cis-butenedioic anhydride
140g, neopentyl glycol 150g, tetramethylolmethane 20g are put in four-hole boiling flask, are then passed through nitrogen in flask, be rapidly heated to
160 to 180 degrees Celsius, then be incubated half an hour after, then in flask add phthalic anhydride 100g, cis-butenedioic anhydride 70g, neopentyl glycol 75g,
Tetramethylolmethane 10g, to 250 degrees Celsius, insulation is cooled to again room temperature to continuous heating after 15 minutes, then by flask in 1 hour
In liquid discharge, it is alkyd resin to be prepared to filter out dope.
Alkyd resin can certainly be made varnish, be add in alkyd resin net urea formaldehyde, wetting dispersing agent,
Ketohexamethylene, then gradually adds butyl acetate under the conditions of the r/min of rotating speed 300 ~ 500, changes it and arrives resultant viscosity.
With reference to JC/T 1074-2008《Function of purifying indoor air coating material purifying property》Detected.By this
Bright made alkyd resin makes varnish and sprays to the upper of 500 mm × 500 mm glass plates respectively with alkyd resin, sprays per block
Painting amount is 200 g.In temperature (20 ± 2) DEG C, relative humidity（50±10）It is dried in % environment after 7 d and tests, net aldehyde effect is surveyed
Shown in test result following table：
| Net aldehyde efficiency | Net aldehyde persistency | |
| Alkyd resin | ≥82% | ≥60% |
| Varnish | ≥75% | ≥95% |
Thus knowable to table, alkyd resin is made into varnish, persistency can only be improved, and net aldehyde efficiency can be reduced, so for
The device that use time is not grown, should not carry out net aldehyde using varnish.
Embodiment two
The present embodiment and the difference of embodiment one are the component ratio for changing alkyd resin, i.e. the present embodiment alkyd resin
It is formulated by the component of following mass fraction：Phthalic anhydride 180g, cis-butenedioic anhydride 150g, neopentyl glycol 160g, tetramethylolmethane 120g.With regard to
The preparation method of alkyd resin is identical with embodiment one with net aldehyde detection method.For comparative illustration, comparative example 1 is increased in addition,
Will the component ratio of alkyd resin change into：Phthalic anhydride 180g, cis-butenedioic anhydride 150g, tetramethylolmethane 120g；Comparative example 2, Du Pont of Du Pont
Beautiful color LC200 general-purpose varnishes.
Embodiment two is directly detected with the alkyd resin of comparative example 1（Rather than make paint after detect again）, adopt
The varnish of example example 2 is detected, its last testing result is：
| Net aldehyde efficiency | Net aldehyde persistency | |
| Embodiment two | ≥62% | ≥61% |
| Comparative example 1 | ≥70% | ≥60% |
| Comparative example 2 | 0 | 0 |
Thus table understands that have changed in embodiment one after the component and ratio of alkyd resin, net aldehyde persistency changes without obvious,
But net aldehyde efficiency but has substantially reduction, existing varnish does not have net aldehyde effect substantially.
The above is only embodiments of the invention, and the general knowledge here such as known concrete structure and characteristic is not made excessively in scheme
Description.It should be pointed out that for a person skilled in the art, on the premise of without departing from present configuration, can also make
The quantity of some deformations and improvement, locating slot and insert sheet for positioning is three.Positioning head is provided with in-line groove or cross bath.
These should also be considered as protection scope of the present invention, and these are all without the effect and practical applicability for affecting the present invention to implement.
This application claims protection domain should be defined by the content of its claim, specific embodiment in description etc. record can
For explaining the content of claim.
