The invention discloses a natural latex composite coagulator, which is composed of a bromelain biological coagulation liquid and a sodium silicofluoride or potassium aqueous dispersion, wherein the dosage of the bromelain biological coagulation liquid is 1%-5% of the total weight of natural latex, and the dosage of the sodium silicofluoride or potassium aqueous dispersion is 0.15%-1.5% of the total weight of the natural latex. When the composite coagulator is used for coagulating fresh latex, under the synergistic effect of pineapple acid biological coagulation liquid and sodium silicofluorideor potassium aqueous dispersion, the basic performance of natural rubber raw rubber is superior to that of raw rubber of acid coagulation fresh latex, the tensile strength is higher than that of acidcoagulation by 3-5 MPa, and thereby the use performance of natural rubber can be effectively improved. 本发明公开了一种天然胶乳复合凝固剂，由菠萝酸生物凝固液和硅氟酸钠或钾水分散体组成，菠萝酸生物凝固液的用量为天然胶乳总重量的1％～5％，硅氟酸钠或钾水分散体的用量为天然胶乳总重量的0.15％～1.5％。使用该复合凝固剂凝固鲜胶乳，在菠萝酸生物凝固
