Zusammenfassung:	The invention discloses a preparation method of a water-repellent carpet non-woven fabric, and belongs to the technical field of carpet non-woven fabric processing. In order to solve the technical problem that the water repellency of the carpet non-woven fabric in the prior art needs to be improved, the preparation method of the water-repellent carpet non-woven fabric comprises the following operation steps: weighing according to parts by weight: adding toluene, hexyl acrylate and a catalyst into a reaction kettle, stirring, dropwise adding a polysiloxane solution into the reaction kettle, and after dropwise adding is completed, adding a catalyst into the reaction kettle; and carrying out a heat preservation reaction for 12-15 h, and carrying out reduced pressure distillation until no liquid flows out to obtain the modified polysiloxane. The prepared water-repellent carpet non-woven fabric has a large static contact angle, the hydrophobicity of a water-repellent carpet is improved, silicon dioxide and polysil
