Abstract
The invention belongs to the technical field of rubber stocks, and relates to a natural rubber stock capable of preventing adhesion to cement, which comprises the following components in parts by weight: 100 parts of constant-Mooney-viscosity natural rubber CV60, 3.0-8.0 parts of zinc oxide, 1.0-2.0 parts of stearic acid, 60-80 parts of carbon black N550, 5.0-8.0 parts of oleamide, 10-25 parts of DOP (dioctyl phthalate), 1.0-2.0 parts of anti-aging agent RD, 1.0-2.0 parts of 4010NA, 1.5-2.5 parts of sulfur, 1.5-2.0 parts of accelerator CZ and 0.1-0.4 part of accelerator TMTD (tetramethyl thiuram disulfide). The natural rubber stock has favorable comprehensive physical properties, satisfies the requirements for capsules for cement precast slabs, and has the advantages of favorable antisticking effect, high work efficiency, long service life and environment friendliness.
Description
Technical field:
The invention belongs to rubber size technical field, relate to a kind of natural gum sizing material with cement adhesion that prevents, the adhesion problems of capsule and cement in cement pre-fabricated panel making processes can be solved with capsule prepared by this natural gum sizing material, increase work efficiency, extend capsule work-ing life.
Background technology:
Natural rubber have good springiness, tensile strength high, tear-resistant, with canvas bond strength advantages of higher, therefore, most capsule natural gum sizing material makes, but when applying in some field, there is serious defect, such as, at building material industry, when making cement pre-fabricated panel, with natural gum capsule as hollow support, after cement solidification, be sticked together with capsule, capsule is difficult to take out, and existing way is at capsule surface spraying releasing agent, but effect is still undesirable, releasing agent can cause certain corrosion to capsule on the one hand; On the other hand, stripping result is bad, and easily tear when capsule is extracted out, and capsule surface is stained with cement, is difficult to clean out, easy adhesion during use, each capsule can only be reused within 5 times.
Summary of the invention:
The object of the invention is to the shortcoming overcoming prior art existence, seeking to design provides a kind of natural gum sizing material with cement adhesion that prevents, the capsule made of this sizing material can solve the adhesion problems of capsule and cement in cement pre-fabricated panel making processes, increases work efficiency, and extends capsule work-ing life.
To achieve these goals, the present invention selects the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60, and in its natural gum sizing material, the weight part of each component is:
Compared with prior art, its comprehensive physical is functional in the present invention, and meet the requirement of cement pre-fabricated panel capsule, anti-adhesion effects is good, and application working efficiency is high, long service life, environmental friendliness.
Embodiment:
Below by embodiment, the invention will be further described.
Embodiment 1:
The present embodiment selects the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60, and the natural gum sizing material comprehensive physical of acquisition is functional, has the sizing material of anti-adhesion effects well, and the weight part of its each component is:
Embodiment 2:
The present embodiment selects the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60, and the natural gum sizing material comprehensive physical of acquisition is functional, has the sizing material of anti-adhesion effects well, and the weight part of its each component is:
Embodiment 3:
The present embodiment selects the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60, and the natural gum sizing material comprehensive physical of acquisition is functional, has the sizing material of anti-adhesion effects well, and the weight part of its each component is:
The test result of the natural gum sizing material of the present embodiment is as shown in table 1.
Table 1:
Claims (1)
1. prevent the natural gum sizing material with cement adhesion, it is characterized in that selecting mooney viscosity ML1+40 be 60 permanent Mooney natural rubber CV60, in its natural gum sizing material, the weight part of each component is:
