Abstract
white carbon black, anti-aging agent, an adhesive, an activating agent, a vulcanizing agent, an accelerator and an anti-scorching agent. The invention is characterized in that the adhesive is the HMMM of which the pass percent is 5%. By adding the HMMM adhesive into the cord fabric rubber instead of the HMT (hexamethylenetetramine) adhesive, the test data displays that the hardness of the cord fabric rubber with the HMMM adhesive is enhanced by 2 degrees, the product of tensile strength and elongation is enhanced by 8.5%, the generation of heat is lowered by 22.8%, and the adhesive force is enhanced by 18.5%. The adhesive is green and environment-friendly, and can be widely popularized in industry.
Description
Technical field
The present invention relates to a kind of cord fabric sizing material, specifically a kind of cord fabric sizing material containing hexamethylolmelamine pregnancy ether.
Background technology
In cord fabric sizing material, the performance of tackiness agent directly affects the bounding force between sizing material and cord, determines the whether superior in quality of the cord produced.Vulkacit H (HMT), as one of the required component of methylene radical donor resorcinol-formaldehyde adhesion system, is the important tackiness agent introducing all-steel load-bearing radial tire at first.But HMT tackiness agent can discharge toxicity formaldehyde in binder resin reaction, can slow oxidation be formic acid in atmosphere, certain corrosive nature can be had to steel wire, therefore not recommendation in steel wire adhesive formula afterwards.
Hexamethylolmelamine pregnancy ether (HMMM), chemical formula C

6, molecular weight 390.4353, be colourless or light yellow viscous liquid under normal temperature, be dissolved in alcohols, be partially soluble in water, its structural formula is as follows:
。
HMMM is also the main source of formaldehyde and methylene radical donor in resorcinol-formaldehyde adhesion system, and the methylene radical that HMMM discharges in binder resin formation reaction can form methylene radical adhesive bond on the spot in sizing material, nontoxicity, is a kind of tackiness agent of very advantageous.
Summary of the invention
The object of this invention is to provide a kind of cord fabric sizing material containing hexamethylolmelamine pregnancy ether.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of cord fabric sizing material containing hexamethylolmelamine pregnancy ether, described cord fabric sizing material is mixed in proportion by rubber, white carbon black, anti-aging agent, tackiness agent, promoting agent, vulcanizing agent, promotor and scorch retarder and processes, and it is characterized in that: described tackiness agent to be mass percent be 5% hexamethylolmelamine pregnancy ether.
The invention has the advantages that: the present invention adopts HMMM tackiness agent to replace HMT tackiness agent to add in cord fabric sizing material, the cord fabric sizing material of HMMM binding agent is added in testing data display, hardness improves 2 degree, Qiang Shenji improves 8.5%, heat-dissipating reduces by 22.8%, bounding force improves 18.5%, and this tackiness agent environmental protection, industrially can magnify and apply.
Embodiment
Technical spirit of the present invention and beneficial effect can be fully understood in order to make the public; applicant will embodiment describe in detail below; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the present invention's design all should be considered as protection scope of the present invention.
Two comparative formula of the present invention in following table 1, in comparative example 1, tackiness agent is HMT, and test adhesive of the present invention is HMMM:
。
Test above-mentioned cord fabric sizing material formula, its physical and mechanical properties test-results is as shown in table 2:
。
Associative list 1 and table 2 known:
1, sizing material hardness improves 2 degree;
2, aging front Qiang Shenji improves (4321-3952)/4321=8.5%;
3, the heat-dissipating of sizing material reduces (24.5-18.9)/24.5=22.8%;
4, the bounding force of sizing material and steel wire improves (717.5-585)/717.5=18.5%.
