Abstract
The present invention provides carpet backing adhesive. A sulfur system of concentrated natural latex is vulcanized to be prevulcanized latex at the constant temperature of 60 DEG C to 65 DEG C, wherein the latex chloroform value of the prevulcanized latex is three in medium and four in primary; stabilizing accessory ingredients are added, and the stabilized prevulcanized latex is used as base glue of the adhesive. Measured by the weight of dry basis, the adhesive comprises the components of 100.0 parts of base glue, 50.0 to 300.0 parts of filling agent, 2.0 to 5.0 parts of coloring agent and 3.5 to 8.5 parts of thickening agent. The method for making the adhesive is composed of four steps of the latex vulcanization, the preparation of the base glue, the preparation of paste of the filling agents and the preparation of the backing adhesive.
Description
The present invention relates to a kind of binder for carpet backing, particularly a kind of binder for carpet backing and manufacture method thereof that adopts natural rubber latex to make.
Woven, acupuncture reaches the backing that carries based carpet and needs adhesive coating, with anchoring villus, stable dimensions, and makes carpet have good paving property, wearing quality and moistureproofness.Therefore, the quality of adhesive quality directly affects the quality and the usability of carpet.Adopt natural rubber latex to make binder for carpet backing, generally be to use the cooperation natural rubber latex, latex does not carry out prevulcanized, but adhesive applicating is vulcanized after the drying to the carpet backing, thereby carpet manufacturing needs special high temperature vulcanized equipment.The binder for carpet backing that present domestic carpet manufacturing is used all is each carpet factory outsourcing pre-vulcanized natural latex, and oneself selects Synergist S-421 95, and weighting agent is processed into tackiness agent.Because prevulcanized latex is not to make the binder for carpet backing special adhesive, its quality and performance variation are big, the adhesive formulation difference selected of each factory in addition, thereby the quality of tackiness agent, performance difference are very big, cause and be both the carpet of producing same description, its quality, performance differ greatly, often because the inferior carpet that causes of adhesive quality is defective.Secondly, the adhesive system instability easily precipitates, layering, flocculation and agglomeration phenomena, so the backing tackiness agent that uses in the carpet actual production all is matching while using.Moreover the tackiness agent that uses needs behind the backing gluing to carry out drying under the temperature about 120 ℃ at present, and energy consumption is big.
It is stable the purpose of this invention is to provide a kind of tackiness agent, storage time is long, in storage, transportation and use, do not precipitate, layering, flocculation, coalescent and rotten, vulcanization curve is smooth, binder for carpet backing that the coating glue film physical and mechanical properties is good and manufacture method thereof.
It is 60-75%(weight that binder for carpet backing adopts total solids level) concentrated natural latex carry out the prevulcanized latex that prevulcanized makes and count 100.0 with butt weight, adding the stablizer casein is 0.5-1.5, potassium oleate is 0.1-0.5, diffusant methylene sodium dinaphthalenesulfonate 0.5-2.0, peregal-0 is 0.2-0.5, tertiary sodium phosphate, trisodium phosphate, sodium polyphosphate, in four sodium-metaphosphates one or more are 0.2-0.5, ammoniacal liquor is 0.2-0.4, permeate agent dibutyl sodium disulfonate 0.05-0.15, accelerant zinc dibutyl dithiocaarbamate or dimethyl, diethyl, the sizing material that in the zinc salt of the dithiocarbamic acid of dibenzyl one or more are made for 0.2-0.5 is a base-material glue.Binder for carpet backing goes out base-material glue, weighting agent, tinting material, thickening material and makes, in butt weight: base-material glue is 100.0, weighting agent is 50.0-300.0, it is 2.0-5.0 that tinting material adopts titanium dioxide, the thickening material carboxymethyl cellulose is 1.5-5.0, the thickening material ammonium polyacrylate is 1.0-2.0, the thickening material gelatin is 0.5-1.5, and the thickening material sodiun alginate is 1.0-3.0.
