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 the rubber size technical field, relate to a kind of natural gum sizing material that prevents with the cement adhesion, can solve the adhesion problems of capsule and cement in the cement pre-fabricated panel making processes with the capsule of this natural gum sizing material preparation, increase work efficiency, prolongation capsule work-ing life.
Background technology:
Natural rubber have good springiness, tensile strength height, tear-resistant, with canvas bond strength advantages of higher, therefore, most capsules are made of the natural gum sizing material, but when in some field, using, there is serious defective, for example, at building material industry, when making cement pre-fabricated panel, use the natural gum capsule as hollow support, after the 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, and releasing agent can cause certain corrosion to capsule on the one hand; On the other hand, stripping result is bad, and capsule tears when extracting out easily, and capsule surface is stained with cement, be difficult to clean out, and easy adhesion during use, each capsule can only be reused in 5 times.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists, seeking to design provides a kind of natural gum sizing material that prevents with the cement adhesion, the capsule of making of this sizing material can solve the adhesion problems of capsule and cement in the cement pre-fabricated panel making processes, increases work efficiency prolongation capsule work-ing life.
To achieve these goals, the present invention selects the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60 for use, and the weight part of each component is in its natural gum sizing material:
The present invention compared with prior art, its comprehensive physicals is good, satisfies the capsular requirement of cement pre-fabricated panel, anti-adhesion effects is good, uses high efficiency, long service life, environmental friendliness.
Embodiment:
Below by embodiment the present invention is further described.
Embodiment 1:
Present embodiment is selected the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60 for use, and the comprehensive physicals of natural gum sizing material of acquisition is good, has the sizing material of anti-adhesion effects well, and the weight part of its each component is:
Embodiment 2:
Present embodiment is selected the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60 for use, and the comprehensive physicals of natural gum sizing material of acquisition is good, has the sizing material of anti-adhesion effects well, and the weight part of its each component is:
Embodiment 3:
Present embodiment is selected the permanent Mooney natural rubber CV60 of mooney viscosity (ML1+40) 60 for use, and the comprehensive physicals of natural gum sizing material of acquisition is good, 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 present embodiment is as shown in table 1.
Table 1:
