Abstract
The utility model relates to a base plate specially used for a low-cost cardanol modifying electronic circuit board, which is widely taken as the base plate of the electronic circuit board of low-grade electronic products such as a domestic appliance, an electronic toy, a telephone set, a light fitting and the like. The base plate is a laminated product which comprises 10-200 layers of bleached wood pulp paper (1); and the bleached wood pulp paper (1) is soaked with cardanol modified phenolic resin (2). The base plate specially used for the low-cost cardanol modifying electronic circuit board is lower in production cost, high in mechanical and dielectric performances and better in high-temperature-resistance and insulation property.
Description
Technical field
The utility model relates to a kind of backing plate.The electronic circuit board that is widely used in low-grade electronic products such as household electrical appliance, electronic toy, telephone set, light fixture is made backing plate.Belong to the insulating materials technical field.
Background technology
In recent years, along with the develop rapidly of electronics industry, also increasing as the consumption of the backing plate in the electronic circuit board manufacturing process.The backing plate that uses is directly to make with the PVC plate now.Its shortcoming is: resistance to elevated temperatures and insulating properties are relatively poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the special-purpose backing plate of the low-cost electronic circuit board of modified by cardanol of a kind of resistance to elevated temperatures and good insulation preformance is provided.
The purpose of this utility model is achieved in that the special-purpose backing plate of the low-cost electronic circuit board of a kind of modified by cardanol, described backing plate is a kind of laminated product, this laminated product includes 10 ~ 200 layers of bleached wood pulp paper, and described bleached wood pulp paper is soaked with modified by cardanol phenolic resins.
The beneficial effects of the utility model are:
1, the utility model is in the phenol formaldehyde resin system, add substituted phenol-anacardol and carry out modification with chain alkyl, pentadecyl phenol phenol-formaldehyde resin modified between the anacardol chemistry is by name, since in the chemical constitution of anacardol therebetween the position pentadecyl long-chain is arranged, therefore use modified by cardanol phenolic resins, be well suited for doing backing material, and cost reduces greatly.
2, the utlity model has high machinery and dielectric properties, and resistance to elevated temperatures and insulating properties are better.
Description of drawings
Fig. 1 is the section structure schematic diagram of the special-purpose backing plate of the low-cost electronic circuit board of the utility model modified by cardanol.
Reference numeral among the figure:
Bleached wood pulp paper 1, modified by cardanol phenolic resins 2.
The specific embodiment
Referring to Fig. 1, Fig. 1 is the section structure schematic diagram of the special-purpose backing plate of the low-cost electronic circuit board of the utility model modified by cardanol.As seen from Figure 1, the special-purpose backing plate of the low-cost electronic circuit board of the utility model modified by cardanol, described backing plate is to soak the laminated product that forms with 2 pressings of modified by cardanol phenolic resins by 10 ~ 200 layers of bleached wood pulp paper 1.
Claims (1)
1. the special-purpose backing plate of the low-cost electronic circuit board of a modified by cardanol, it is characterized in that: described backing plate is a kind of laminated product, this laminated product includes 10 ~ 200 layers of bleached wood pulp paper (1), and described bleached wood pulp paper (1) is soaked with modified by cardanol phenolic resins (2).
