Problems solved by technology

[0005] However, we have found that the above-mentioned amino baking varnish has such disadvantages during use, that is, due to the water-based paint, the drying speed is slow during the drying process, which affects the production efficiency, and in order to solve this problem, before use The drying process is accelerated by adding a drier, which will inevitably cause environmental pollution and also cause harm to operators, thereby affecting the industrial utilization of this water-soluble amino baking varnish.

Abstract

The invention relates to a water-soluble alkyd resin used for a toy lacquer, which comprises the following components in portion by weight: 180 to 200 portions of tall oil acid, 60 to 70 portions of trimellitic anhydride, 80 to 100 portions of diglycol, 50 to 60 portions of pentaerythritol, 30 to 40 portions of trimethylolpropane diallyl ether, 60 to 70 portions of dimethylolpropionic acid, 1 to 2portions of hypophosphorous acid, 8 to 10 portions of ammonia water, and 500 to 520 portions of vaal water. The invention also discloses a water-soluble alcohol acid toy lacquer prepared by using thewater-soluble alkyd resin as a principle component, and the synthesized water-soluble alkyd resin can be dried into a film without adding a drier; besides, because the formulation of the toy lacquerprepared by using the water-soluble alkyd resin as the principle component adopts water-soluble components, the toy lacquer achieves zero VOC, contains no heavy metal ions, and meets the requirementson the environmental protection performance of the resin.

Description

technical field [0001] The invention relates to the field of paints, in particular to an alkyd resin component and a toy paint containing the alkyd resin component. Background technique [0002] At present, paint is often used as the coating on the surface of the product in the toy manufacturing process. According to the characteristics of the toy manufacturing process, the drying coating made of amino resin and alkyd resin is usually the preferred coating. The coating formed by this coating The film has high gloss and hardness, water resistance and weather resistance are superior to alkyd coatings, and it can be operated in an assembly line, and the operation is extremely convenient. [0003] Traditional amino drying coatings are usually solvent-based, and a large amount of toxic organic solvents will be volatilized during the drying process, which not only pollutes the operating environment and brings physical damage to the workers, but also brings fire hazards and pollute...
