As a preference of the present invention, calcination kleit preparation method is as follows：Kaolin starting material is taken to be calcined, calcining temperature
Degree is 4.2 DEG C/min from 500 DEG C of linear temperature increases to 750 DEG C of heating rates, is then calcined again at 750 DEG C 1 hour, the mistake of calcining
Oxygen concentration in journey in combustion chamber is maintained at 50% state, after the completion of calcining under vacuum conditions, is discharged after natural cooling,
Kaolin is finally stirred into the powder that particle mean size is less than 350 nanometers.
As a preference of the present invention, the stir speed (S.S.) of the mixer is 400r/min, mixing time is 6 hours.
As a preference of the present invention, the preparation method of the hydrophobicity paraffin is as follows：The paraffin of 1 parts by weight is taken to be added to 8
Among the acetone of parts by weight, it is heated to 55 DEG C and stirs 45min using mixing speed as 200r/min stir speed (S.S.), form paraffin
Solution, the stir speed (S.S.) that then 3 parts of deionized water is added among paraffin solution and using mixing speed as 600r/min is stirred
Mix 30min.
As present invention further optimization, parts by weight are made up of following components, 12 parts of polyvinyl alcohol, calcined kaolin 8
Part, 5 parts of silica gel of vulcanization, 8 parts of sodium metasilicate, 15 parts of acrylic acid, 6 parts of sodium hydroxide, 10 parts of potassium chlorate, 3 parts of polyurethane, 2 parts of polyureas,
5 parts of hydrophobic nano-silica, 3 parts of hydrophobicity paraffin, 30 parts of water.
Beneficial effect：
（1）With good shock resistance fatigue effect, extreme weather prone areas external wall waterproof materials'use can be used as；
（2）It with good mobility, can penetrate among the interior layer gap of material, make the water resistance of material better.
Embodiment
Make specific introduce to the present invention below in conjunction with specific embodiment.
A kind of water-repellent paint, it is characterised in that its parts by weight is made up of following components, 10 ~ 15 parts of polyvinyl alcohol, calcining is high
8 ~ 12 parts of ridge soil, vulcanizes 5 ~ 10 parts of silica gel, 5 ~ 10 parts of sodium metasilicate, 15 ~ 20 parts of acrylic acid, 6 ~ 8 parts of sodium hydroxide, potassium chlorate 9 ~ 12
Part, 3 ~ 5 parts of polyurethane, 2 ~ 3 parts of polyureas, 5 ~ 10 parts of hydrophobic nano-silica, 3 ~ 5 parts of hydrophobicity paraffin, 30 ~ 45 parts of water.
Calcination kleit preparation method is as follows：Kaolin starting material is taken to be calcined, calcining heat is from 500 DEG C of linear temperature increases
It is 4.2 DEG C/min to 750 DEG C of heating rates, is then calcined again at 750 DEG C 1 hour, the oxygen during calcining in combustion chamber
Gas concentration is maintained at 50% state, after the completion of calcining under vacuum conditions, discharges, finally stirs kaolin after natural cooling
Into the powder that particle mean size is less than 350 nanometers.
The stir speed (S.S.) of mixer is 400r/min in the present embodiment, and mixing time is 6 hours.
