The invention discloses a high-solid-content paint antiwrinkling diluent, and in particular relates to the technical field of chemical coating. The high-solid-content paint antiwrinkling diluents comprises the following components: 2 to 36 parts of beewax, 2 to 27 parts of lecithin, 2 to 31 parts of a castor oil hydrogenation mixture, 2 to 19 parts of alkyl benzoate, 3 to 30 parts of carrageenan, 3 to 19 parts of cetearyl alcohol, 2 to 59 parts of dibutylhydroxytoluene, 2 to 37 parts of diisopstearate, 2 to 19 parts of silicon resin, 1 to 5 parts of hectorite, 0.5 to 5 parts of silicone oil, 2 to 23 parts of vaseline, 3 to 45 parts of deionized water, 2 to 19 parts of tea tree oil and 2 to 16 parts of myristyl myristate. The high-solid-content paint antiwrinkling diluent can reduce the phenomenon that the surface of the paint film is dried in advance, but the internal paint film is too late to dry to form wrinkle when high temperature weather and solar exposure is just met, or the construction site is improper in ventilation, and also can reduce wrinkles caused by different drying rate of the two layers of paint films when the coating which is dried quickly and the coating which is dried slowly are mixed and used; and the diluent is soft, safe, non-toxic and high in applicability, and can reduce the phenomena of foaming, feather-shaped cracking and stripes of the high-solid-content paint during use.
