specific Embodiment approach 1
[0008] Specific embodiment one: the preparation method of curing agent for epoxy floor paint in this embodiment is as follows: 103g diethylenetriamine and 107g phenol are mixed under stirring until exotherm occurs, add 33g paraformaldehyde and 100g cashew nuts oil, heated to 65°C to react for 1 hour, then heated to 75°C, kept warm for 1 hour, and vacuum dehydrated to obtain a curing agent for epoxy floor paint.
[0009] The curing agent of the present invention is added to the epoxy floor paint according to 10% of the mass of the epoxy floor paint, and the wear resistance is measured, and the wear resistance (750g / 500r) is 0.04.

The invention discloses a curing agent for epoxy floor paints and a preparation method thereof, belonging to the technical field of epoxy floor. The invention aims to solve the technical problems of poor wear resistance and high scratching tendency in the existing epoxy floor paint. The curing agent is prepared from the following components in parts by weight: 100-105 parts of diethylenetriamine, 105-110 parts of phenol, 30-35 parts of polyformaldehyde and 95-100 parts of cashew oil. The preparation method comprises the following steps: mixing and stirring the diethylenetriamine and phenol until heat release appears, adding the polyformaldehyde and cashew oil, heating to 65 DEG C, reacting for 1 hour, heating to 75 DEG C, keeping the temperature for 1-2 hours, and carrying out vacuum dehydration to obtain the curing agent for epoxy floor paints. The wear resistance (750g/500r) is up to 0.04.
Description
technical field [0001] The invention belongs to the technical field of epoxy floor, and in particular relates to a curing agent for epoxy floor paint. Background technique [0002] Epoxy resin has a certain thermoplasticity, needs to react with curing agent or fatty acid, and cross-links to form a network structure macromolecule, from its own thermoplasticity to thermosetting, thus showing various excellent properties. Among them, there are many epoxy resin floor paints, and each has its own characteristics. The existing epoxy floor paint has poor wear resistance and is prone to scratches. Contents of the invention [0003] The invention solves the technical problem that the existing epoxy floor paint has poor wear resistance and is prone to scratches; and provides a curing agent for the epoxy floor paint and a preparation method thereof. [0004] In the present invention, curing agent for epoxy floor paint is made by 100~105 parts of diethylenetriamine, 105~110 parts ...
