Abstract

The embodiment of the invention discloses latex. The latex comprises the following components in parts by weight: 100 parts of natural latex, 0.4 parts of zinc oxide, 2.5 parts of solid paraffin, 0.5 part of casein, 0.4 part of potassium hydroxide, 0.8 part of an accelerant PX, 3 parts of an anti-ageing agent DBH, 5 parts of sulfur and 3 parts of paint, wherein the components are 115.6 parts in total; the technical conditions are that the total solid content is 50% to 52%, the chloroform number is 2 and the viscosity is 20+/-5mpa's. By using an improved formulation process, the latex disclosed by the invention can be used for increasing the flexibility and pigmentation degree of a latex finished product.

Description

A kind of latex

Technical field

The invention belongs to latex preparing technical field, particularly a kind of latex.

Background technology

Latex is widely used in various technique and industrial production, especially as greatly extensive in the application on mask, headgear, cartoon figure and various toy at American-European holiday gift.The technology that in tradition, latex generates is exactly that natural emulsion adds some promotor and pigment, the traditionally formula of emulsion technique, and its product made also exists following deficiency: a) hardness is comparatively large, and snappiness is not strong, easily tears; B) do not have the shake sense of muscle during motion, fidelity is poor; C) tinctorial property is bad, easily fades.

Therefore, for the above-mentioned defect existed in currently available technology, be necessary to study in fact, to provide a kind of scheme, solve the defect existed in prior art, avoid causing above emulsion products Problems existing.

Summary of the invention

For solving the problem, the object of the present invention is to provide a kind of latex, being added snappiness and the degree of staining of latex finished product by the Recipe improved.

For achieving the above object, technical scheme of the present invention is:

A kind of latex, the component of this latex is:

Natural emulsion 100 parts, 0.4 part, zinc oxide, solid paraffin 2.5 parts, casein 0.5 part, 0.4 part, potassium hydroxide, promotor PX0.8 part, antioxidant DBH 3 parts, 5 parts, sulphur, pigment 3 parts, add up to 115.6 parts, technical qualification are total solids level 50%-52%, in chloroform value two, and viscosity 20 ± 5mpa's.

Compared with prior art, beneficial effect of the present invention is as follows:

(1) decrease the content of solid paraffin, overcome the problem that latex finished product is partially hard;

(2) reducing zinc oxide content for strengthening solubility, raising sulfur content and overcoming the painted problem easily falling paint of latex finished product;

(3) add anti-aging agent, promotor, significantly enhance the toughness of latex finished product, overcome the problem that goods are easily torn.

Embodiment

In order to make object of the present invention, technical scheme and advantage clearly understand, below the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

On the contrary, the present invention is contained any by the substituting of making on marrow of the present invention and scope of defining of claim, amendment, equivalent method and scheme.Further, in order to make the public have a better understanding to the present invention, in hereafter details of the present invention being described, detailedly describe some specific detail sections.Do not have the description of these detail sections can understand the present invention completely for a person skilled in the art yet.

The latex that the embodiment of the present invention provides, its component is as follows: natural emulsion 100 parts, 0.4 part, zinc oxide, solid paraffin 2.5 parts, casein 0.5 part, 0.4 part, potassium hydroxide, promotor PX0.8 part, antioxidant DBH 3 parts, 5 parts, sulphur, pigment 3 parts, add up to 115.6 parts, technical qualification are total solids level 50%-52%, in chloroform value two, and viscosity 20 ± 5mpa's.By latex product prepared by above component, advise 90 newton by U.S.A, maintain the tensile test of 10 seconds, reliably painted, the varnished 1mm drawn by cutter ²* 100 lattice, be the PASS test that miter angle oppositely firmly tears up with 3M gummed paper, due to good with skin avidity, effect is true to nature, painted reliable good characteristics.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
