The invention discloses an epoxy resin bonding agent cured at the normal temperature for roads and bridges. The epoxy resin bonding agent comprises a component A and a component B, wherein the component A comprises the following ingredients in parts by mass: 100 parts of epoxy resin, 30-40 parts of flexible epoxy resin, and 5-15 parts of a diluent; the component B comprises the following ingredients in parts by mass: 60-70 parts of a curing agent, 3-5 parts of a flexibilizer, 1-3 parts of an accelerant, and 0.2-0.5 part of a defoaming agent; the ratio of the component A to the component B is (100:80)-(100:100). According to the invention, the flexible epoxy resin is added into the commonly-used epoxy resin, and after the flexible epoxy resin reacts with the curing agent, a thermoset three-dimensional crosslinking structure is formed, so that the good flexibility, better bonding capacity and water resistance are achieved; cashew nut shell oil modified amine is used as the curing agent, so that the water resistance and low temperature resistance of the bonding agent are improved effectively; in addition, since novel multiple-alcohol derivative is used as the flexibilizer of the epoxy resin, the toughness of the epoxy resin is effectively improved, so as to adapt to deformation of steel bridge decks or cement concrete bridge decks during vibration, and realize the purpose of high durability of the epoxy resin bonding agent solidified at the normal temperature for roads and bridges. The epoxy resin bonding agent solidified at the normal temperature for roads and bridges is suitable for bonding and water resistance of steel bridge decks, urban viaducts, cement concrete bridge decks, tunnels and pavements of expressways and the like. The invention further discloses a preparation method of the epoxy resin bonding agent.

The invention relates to an additive for bright nickel plating technology for a permanent magnetic material. The additive comprises a primary brightening agent, a secondary brightening agent and an auxiliary additive, wherein the primary brightening agent is a compound containing an acetylenic bond or sulfonyl; sulphur in the sulfonyl is positive quadrivalent or positive hexavalent; and the secondary brightening agent is a pyridine derivative. By a combination of the pyridine derivative, a ynamine compound and a propiolic alcohol derivative and a combination of a softening agent (impurity removing agent) and a low-foam wetting agent, the novel additive for the bright nickel plating technology is prepared, and has high bright dipping speed, high dispersibility, high color and luster uniformity, fewer decomposition products, long processing cycle, high level, good ductility, high impurity tolerance, low stress and excellent electrochemical performance.
