Abstract
A composite damping sheet is composed of a damping sandwich layer consisting of a dampin layer prepared from the mixture of asphalt and elastomer and the additive chosen from damping increaser, strength increaser and filler and a reinforcing fibre layer made of metallic fibre fabric, non-metal fibre fabric, or high-molecular fibre fabric, and an external film layer made of plastic film, metallic film, or composite film.
Description
(1) technical field
The present invention relates to a kind of damping sheets, be particularly useful for aspects such as building, plant equipment, the vehicles.
(2) background technology
Existing various damping sheets, its damping ratio generally only are about 0.20, and price height, low, the poor durability of intensity.For damping layer material is when containing the elastomer blend of pitch, and cold flow (also flow deformation) and phenomenon such as aging can take place at pressurized or when being heated.
(3) summary of the invention
The objective of the invention is to solve existing damping material is when containing the elastomer blend of pitch, cold flow (also flow deformation) and shortcoming such as aging can take place easily at pressurized or when being heated, and provide a kind of can effectively avoiding to issue raw and cold flow phenomenon and prevent the damping sheets that damping layer is aging when the excessive condition of overhigh temperature of ambient pressure.
For this reason, the present invention takes following technical scheme:
A kind of composite damping sheets comprises damping layer material, and sandwich is compounded with one deck fiber-reinforced layer at least in the described damping layer material, and the damping layer appearance is coated with thin layer, and described thin layer is totally-enclosed film, and described damping layer material contains additive; Described damping layer material can be one of the following: the 1. elastomeric blend of pitch and SBS, 2. the elastomeric blend of pitch and APP, 3. the elastomeric blend of pitch and EVA, the 4. elastomeric blend of pitch and CPE, 5. pitch and two or more above-mentioned elastomeric blend.
Further, the additive in the described damping layer material include following one or more: 1. damping reinforcing agent, 2. intensity reinforcing agent, 3. packing material.
Described damping reinforcing agent can be one of the following: 1. mica sheet powder, 2. lead powder.
Described intensity reinforcing agent can be one of the following: 1. durafiber, 2. polyester staple fiber, 3. glass fiber short fiber.
Described packing material can be one of the following: 1. talcum powder, 2. rubber powder, 3. wood chip.
Described fiber reinforcement layer material can be one of the following: 1. metal fibre interlacement, 2. non-metallic fibers fabric, 3. macromolecular fibre fabric.
Described thin layer material can be one of the following: 1. plastic sheeting, 2. metallic film, 3. laminated film.
Advantage of the present invention is: the sheet material outer surface is coated with the thin layer of sealing, thereby can avoid issuing raw and cold flow phenomenon and preventing that damping layer is aging when the excessive condition of overhigh temperature of ambient pressure; Sandwich is compounded with fiber-reinforced layer in the damping layer, and damping layer material contains multiple additives, thereby makes it to have following characteristics: high damping, high strength, price are low, good endurance, can conveniently process.
